Introduction :-

SAP clients who are hoping to execute SAP HANA in the SAP BW climate have a few decisions to make concerning the best method for completing that sending. Clients with an adult SAP BW climate normally think about an OS/DB Migration. Different clients see a SAP HANA sending as a chance to scrub a current climate by setting up another scene and physically moving the arrangements from a current execution to another establishment. The two choices have their advantages and their difficulties.

About the Technology :-

• SAP HANA is a SAP information base innovation that is intended for superior execution. The SAP HANA’s unique trademark is its in-memory approach: all information is put away in the primary memory. Handling enormous information volumes is consequently considerably more productive than it is with customary information bases that initially need to stack the information from the optional memory (hard plate) with fundamentally longer access times. Be that as it may, SAP HANA isn’t as it were a simple in-memory arrangement.


• Customary information bases as of now have fitting storing techniques that can likewise be utilized to get to areas of the dataset productively. SAP HANA gives another capacity: the utilization of the in-memory innovation in mix with extra creative 1 Introduction to SAP BW on SAP HANA 18 programming advances. This incorporates section based information dealing with, the use of refined pressure and access methods, and the dividing of information base tables. Area 1.4 talks about this in more detail. SAP HANA machine Notwithstanding these creative programming innovations, the use of an proper equipment stage is one of the interesting attributes of SAP HANA. To synchronize the product and equipment parts in an ideal way, you can work SAP HANA only on guaranteed equipment stages (SAP HANA machine).


• This approach guarantees that the equipment utilized has the necessary assets (primary memory, store size, number of processors, and so forth) to process however many assignments as could be expected under the circumstances in equal. Presently, just two working frameworks (SUSE Linux Enterprise and Red Hat Enterprise Linux) can be utilized with SAP HANA, which takes into account extra calibrating among programming, equipment, and working framework. So when you buy a SAP HANA machine, the equipment is conveyed with streamlined working framework boundaries and pre-introduced SAP HANA programming.


• Next to each other approaches At the point when SAP HANA was reported in spring 2010 and carried out by chosen clients in November of that very year, the main decisionmakers previously perceived that this innovation could wipe out basic execution issues inside the SAP framework scene. At that time, notwithstanding, nobody was prepared to trade a demonstrated information base arrangement of an extremely youthful SAP HANA innovation.

• Consequently, next to each other methodologies became famous: SAP HANA was utilized in equal, or next to each other, to as of now existing frameworks. The idea of this approach is to ceaselessly imitate the information from a somewhat sluggish data set to the SAP HANA information base and to involve SAP HANA for a high execution information investigation. As a general rule, one might recognize the information shop and the gas pedal methodology.


• The danger appeared to be excessively high that the business could be impacted by potentially juvenile programming. Hence, one next to the other methodologies became well known: SAP HANA was utilized in equal, or next to each other, to as of now existing frameworks. The idea of this approach is to ceaselessly imitate the information from a fairly sluggish data set to the SAP HANA information base and to involve SAP HANA for a high execution information investigation.


• As a general rule, one might recognize the information shop and the gas pedal methodology. Side-by-Side and Integrated Approaches Information shop approach (left side) delineates with a SAP ERP framework, the information shop approach persistently reproduces the information from any data set (frequently called AnyDB in writing) to the SAP HANA information base. Explicit investigation instruments can then straightforwardly get to this information utilizing new points of interaction, like SAP Group.


• At the point when SAP HANA was reported in spring 2010 and carried out by chosen clients in November of that very year, the main decisionmakers previously perceived that this innovation could kill principal execution issues inside the SAP framework scene. At that time, notwithstanding, nobody was prepared to trade a demonstrated information base arrangement of an exceptionally youthful SAP HANA innovation. The danger appeared to be excessively high that the business could be impacted by conceivably youthful programming.


• In this way, one next to the other methodologies became well known: SAP HANA was utilized in equal, or one next to the other, to as of now existing frameworks. The idea of this approach is to consistently repeat the information from a somewhat sluggish data set to the SAP HANA data set and to involve SAP HANA for a high execution information examination. By and large, one might recognize the information shop and the gas pedal methodology.

Types :-

SAP HANA supports 7 categories of SQL data types and it depends on the type of data you have to store in a column.

• Numeric
• Character/ String
• Boolean
• Date Time
• Binary
• Large Objects
• Multi-Valued

Tools :-

The agenda instrument computerizes the check of best practice rules for activities and requirements for relocation of a current SAP BW arrangement to the SAP HANA stage and to SAP BW/4HANA. This was the main apparatus of this series that I created and it currently incorporates very nearly 300 different really take a look at schedules. It’s the most effective method for really looking at your SAP BW framework (regardless of whether you intend to moved to SAP HANA yet).




Today, SAP HANA is a developed item, and on second thought of next to each other approaches, coordinated methodologies lay down a good foundation for themselves, in actuality. Contrasted with the information shop and gas pedal methodologies, the principle distinction is that SAP HANA doesn’t run in corresponding to a current information base arrangement; all things considered, SAP HANA is coordinated into the accessible design andreplaces the old information base.






Thusly, information should be neither imitated nor held repetitively. In view of the case of a current SAP ERP framework, shows how SAP HANA replaces the old information base at the point when the coordinated methodology is utilized. Prophet, DB2, MSSQL, or any other data set is supplanted with SAP HANA inside the extent of a specialized relocation. Because of the presentation qualities of SAP HANA, this trade as of now prompts an extensive speed increase in the relating applications.

History :-

In light of your every day work with SAP BW, you might know a few limitations that the SAP BW framework has, and have wished, once, for a innovation to keep away from them. Coming up next are a few vital limitations for SAP BW: Low execution and significant delays in revealing Extensive time and exertion for change and burden processes Repetitive information maintenance and resolute information displaying High organization exertion for the SAP BW framework and the IT foundation Low execution what’s more long pausing times One of the significant limitations of SAP BW is the somewhat low exhibition during the execution of reports and examinations.






Contingent upon the sum and intricacy of the information, the handling of individual investigation steps in the SAP BW framework might require a few minutes and subsequently sluggish down the cycles in the different business divisions altogether. In one year, this can add up to various hours that representatives need to stand by.The conceivable symptoms of this incorporate a decreased nature of work. Change and load processes Change and load processes additionally require a ton of time in SAP BW.

Scope :-

• Subsequently, the comparing processes run around evening time or toward the end of the week. This ought to guarantee that the framework assets are mostly accessible for examinations and are not impacted by running foundation processes. The time periods that are accessible for the change and burden processes become progressively more modest: because of the worldwide climate, it is at this point not adequate when a worldwide SAP BW framework is accessible for revealing just between 6 a.m. furthermore 8 p.m. EST.





• To assess functional undertaking information, SAP HANA gives new approaches. It considers detailing and examinations regardless of whether you use a SAP BW framework. For this reason, the framework makes individual information models (SAP HANA sees) inside SAP HANA that can be straightforwardly gotten to by examination apparatuses.


• For instance, assuming a SAP ERP framework runs on SAP HANA, you can assess information straightforwardly in SAP Lumira or SAP Analysis Edition for Office utilizing the comparing SAP HANA sees. Furthermore, on the off chance that you use SAP BusinessObjects Design Studio, you can likewise make dashboards that depend straightforwardly on SAP HANA sees.


• The benefit is that all information is accessible for assessments continuously, and you no more need to repeat the information to a SAP BW framework in a tedious cycle. The weakness, in any case, is that the information from various SAP frameworks can’t be just consolidated or orchestrated inside the extent of the investigation. For this reason, an extra SAP BW framework is important.

• By the by, it is useful to utilize functional investigation with SAP HANA in chose execution situations. All things considered, it turns out to be more what’s more important to stretch out these time periods to guarantee access from different nations and time regions. In the event that the information from more locales and nations is midway converged in SAP BW, the information volume likewise increments. Therefore, it becomes more diligently to settle this contention with the current IT foundation.

Advantages :-

In light of your every day work with SAP BW, you might know a few limitations that the SAP BW framework has, and have wished, once, for a innovation to keep away from them. Coming up next are a few vital limitations for SAP BW: Low execution and significant delays in detailing Extensive time and exertion for change and burden processes Repetitive information maintenance and rigid information displaying High organization exertion for the SAP BW framework and the IT foundation Low execution what’s more long pausing times One of the significant limitations of SAP BW is the somewhat low presentation during the execution of reports and investigations.




Contingent upon the sum and intricacy of the information, the handling of individual examination steps in the SAP BW framework might require a few minutes and in this manner slow down the cycles in the different business offices altogether. In one year, this can add up to various hours that workers need to pause. The conceivable results of this incorporate a diminished nature of work. Change and load processes Change and load processes likewise require a ton of time in SAP BW. Thus, the comparing processes run around evening time or toward the end of the week.






This ought to guarantee that the framework assets are basically accessible for examinations and are not impacted by running foundation processes. The time periods that are accessible for the change and burden processes become progressively more modest: because of the worldwide climate, it is presently not adequate when a worldwide SAP BW framework is accessible for announcing just between 6 a.m. furthermore 8 p.m. EST. All things considered, it turns out to be more also more important to stretch out these time periods to guarantee access from different nations and time regions.




Assuming the information from more locales and nations is halfway converged in SAP BW, the information volume likewise increments. Therefore, it becomes more earnestly to address this contention with the current IT framework. One shortcoming first-presented with functional investigation was that pre-SAP HANA Live characterized information models and reports would disappear, driving clients to make them manually. Today, default information models for the most significant SAP HANA items are given SAP HANA Live. Similar to SAP BW content, a virtual information model is presently accessible that joins SAP HANA sees in various layers. Contingent upon your permit, you can likewise adjust or expand the SAP HANA sees exclusively.

SAP HANA information Models :-

• You may wonder why information models are important in SAP HANA at all. To address this inquiry, we should investigate. Sadly, the information that should be dissected is seldom given in just one table; e.g., ace information and the relating texts are normally put away independently. Assuming a report should list material texts notwithstanding explicit material properties, then, at that point, the different tables should be connected to one another.





• The significant key figures are likewise frequently given in explicit tables. If you need the framework to assess these key figures utilizing various qualities, the reconciliation of additional tables is required. The outcome is a complicated design of tables, otherwise called a star pattern, in the SAP BW region.


• Notwithstanding, you can in any case connect the different tables with one another utilizing the relating SQL orders to take into account an assessment. Notwithstanding, it is more proficient to utilize the generally referenced SAP HANA sees in light of the fact that they are SAP HANA modules (e.g., OLAP Engine) improved to perform computations at a high velocity to recover information impressively quicker. Section gives more data on this.


• SAP HANA sees are displayed in SAP HANA Studio. This device depends on SAP HANA Studio Overshadow and is the focal turn of events and organization apparatus. SAP HANA Studio upholds clients with a graphical demonstrating view for the production of SAP HANA sees.


• Like SAP BW protests, the made SAP HANA sees should in any case be enacted or conveyed at the finish of the cycle. A while later, they are accessible in different examination apparatuses, like SAP Lumira, SAP Analysis Edition for Office, or SAP BusinessObjects Design Studio. The turn of events and demonstrating climate of SAP HANA Studio is point by point examines the organization choices of the SAP HANA data set.

Feature :-

In the wake of providing you with an outline of SAP HANA, this part portrays which current difficulties in the SAP BW climate persuade more and more undertakings to utilize SAP BW on SAP HANA. This segment initially dissects how the overall conditions have changed, and afterward it represents the burdens of social data sets according to the specialized point of view. Due to these inconveniences, before, information was frequently kept in different frameworks, every one of which were streamlined for a specific reason. A disseminated and excess information idea, nonetheless, presents new business difficulties to ventures. These difficulties are depicted toward the finish of this segment.

Certification :-

• Ensured equipment is required especially for the useful utilization of SAP HANA. SAP has effectively affirmed a few servers from most SAP equipment accomplices for use with SAP HANA. The confirmation interaction really looks at the equipment parts for their presentation; this includes the speed of processors, the fundamental memory, and their proportion.
• For a SAP BW on SAP HANA framework, for instance, the important proportion is 16GB per processor center when utilizing a 8-center processor. Also, the speed of the organization interface and hard drives is considered.



• At the second, support is given for servers Intel processors as it were. Servers that have passed this cycle effectively are recorded in the Product Availability Matrix (PAM). They are partitioned into servers that are run with SUSE Linux Enterprise Server for SAP Applications or with Red Cap Enterprise Linux.
• Some of them additionally support virtualization by means of VMware vSphere for live activity. Custom-made server farm mix The custom-made server farm joining is another option. Here, you can exclusively gather the equipment bundle, which is typically conveyed in an apparatus, in collaboration with your equipment accomplice.
• To get to the particular information records productively, social data sets use data set lists. This record structure speeds up the inquiry cycle and arranging by specific credits in the data set. Be that as it may, the formation of these sorts of lists is tedious.
• Moreover, you should refresh the list structure subsequent to embedding another information record. The SAP BW framework likewise utilizes records inside for execution streamlining. For instance, an InfoCube might have a record to speed up read gets to.
• At the point when new information records are imported to the InfoCube, this file must additionally be refreshed; be that as it may, especially in the event of enormous information sums, this may postpone the heap cycle. It is quicker to erase the list prior to setting off the heap interaction and afterward make it once again after consummation of the heap process.

Pre-requisition :-

The course of memory portion is proceeded up to a predefined limit, alluded to as worldwide assignment limit. If more fundamental memory is needed past this breaking point, involved memory should be delivered once more. For this reason, information base tables are “dumped,” at the end of the day, eliminated from the fundamental memory. Then, at that point, they are accessible just on the hard circle and never again benefit from the principle memory’s speed. For this situation, SAP HANA attempts to dump information that has not been utilized for quite a while, and it is fit for eliminating as it were portions of tables from the principle memory. It is likewise conceivable to predefine tables that should be dumped first in such a case.




In a SAP BW framework, this basically concerns information from PSA tables and compose improved DSOs, which are not utilized for assessment or investigation in standard activity. Adequate dimensioning of equipment preferably forestalls the dumping of tables. Exemptions include exercises with an especially high principle memory use, for instance, information base updates. This is a normal model for one of the numerous improvements that SAP created in participation with different equipment accomplices.




Fundamental memory factors It is not difficult to distinguish a primary memory deficiency; in any case, it is fairly hard to decide the genuine fundamental memory utilization of SAP HANA. For this reason, we’ll examine primary memory the board in more detail. It shows a few principle memory factors that happen in the course of information base activity.

Conclusion :-

The dimensioning of equipment, just as the data set developments of SAP HANA, satisfy their potential especially when you send the programming that was created on this premise. Existing items like SAP BW have been adjusted for this reason. Furthermore, a whole item arrangement of local SAP HANA applications emerges. We should now talk about the question of how to work them mutually. The first working idea of SAP HANA incorporated a devoted (that is, sole) activity of the data set on the server. It was not delivered for useful frameworks to utilize a few applications on a SAP HANA machine or a few data sets on a server. Meanwhile, the guidelines are impressively more adaptable and grow further. Therefore, we can give just a preview that outlines the extra choices that open up and where you can acquire data on the important subjects.
