    Ans:

    According to the ABAP Dictionary, cluster and pooled tables are particular types. A table pool or table cluster can hold data from several tables. Seated as pooled tables or cluster tables belong to a table pool or cluster. A table pool should be used, particularly for storing data related to internal controls. The control data can be program settings, screen sequences, transient data, and ongoing texts like documentation. Transparent tables are used to contain data with commercial importance.

    36. What is the primary distinction between transparent tables and pool tables?

    Ans:

    The primary distinction between transparent and pool tables is that the latter has a one-to-one link with the database table. In contrast, the former have a many-to-one relationship.

    37. Describe the ABAP Data Dictionary.

    Ans:

    Data definitions (metadata) are created and managed using the ABAP Dictionary. Redundancies in the essential descriptions of all the data utilized in the system can be avoided thanks to the ABAP Dictionary. All of the system’s components automatically receive new or updated information. This guarantees data accuracy, data consistency, and security. Table types and user-specified data items can be defined using the ABAP Dictionary. These data definitions can generate connected items (tables or views) in a simple relational database. The logical structure of the objects used in application development is described in the ABAP Dictionary. Through tables or views, these items demonstrate how they are connected to the underlying relational database.

    ABAP Data Dictionary

    39. Could you describe a few key terms in the ABAP Dictionary?

    The following are a few of the most important object types in the ABAP :

    Tables : Tables are defined separately in the database’s ABAP dictionary. Opinions

    Views : Views are logical perspectives on many tables. The ABAP Dictionary defines the view structure. This structure can be used to build a database overlook.

    Types : In ABAP programs, the type structure can be declared globally. Any applications that use a type automatically become aware of any changes made to it.

    Lock objects : Lock objects are used to synchronize different users’ access to comparable data.

    40. How does the ABAP Data Dictionary define structure?

    Ans:

    The structure is a data item composed of different data types individually stored in memory as components. Structures are similar to a user-defined data type. It can be accessed from ABAP programs and functions similarly to a table for the Data Dictionary. Runtime data is stored in the structure.

    41. What are the work area and internal tables?

    Ans:

    Runtime data is stored in internal tables and work regions, which are types of temporary memory. These are examples of internal tables and database tables. An object of the standard data type is the Work Area. These tables are only present while the program is running. Table operations on subsets of database tables are carried out using it to rearrange database table contents to suit user needs better.

    42. What is an ITS? What benefits does ITS offer?

    Ans:

    In the database, a transparent table has a one-to-one relationship. The dictionary table is identical to the R3 table regarding name, number of fields, and field names. Application data (Master and Transaction) are displayed in a clear table.

    53. What kinds of LUWs are there?

    Ans:

    Two categories of LUW exist :

    DB LUW : The database uses a technique called a database LUW to guarantee data consistency. A database commit marks the conclusion of the linked series of database activities. Following a successful database LUW execution, the database will be steady. Any databases affected by an error in a database LUW will also be affected. As a result, the database is restored to its initial state.

    SAP LUW : It is a coherent unit made up of conversational steps. These modifications to these steps are recorded in a single database. A LUW is known as a SAP LUW. There can be multiple dialogue steps in an SAP LUW. It can be carried out using several distinct work procedures.
