Q & A answers

6. What is the name of the FM generated when the Lock Object is activated?
Answer: Create a lock object in the ABAP dictionary before setting a lock in the ABAP program. When a lock object is created, the system automatically generates two FM pairs for Lock management.
The FM used to set the lock is: enqueue _ <Lock Object Name>. It is used to generate a lock entry in the lock table ). If the lock fails, it will be reflected in return.
The FM used to release the lock is: dequeue _ <Lock Object Name>. It is used to delete a lock entry from the lock table. In the ABAP program, you only need to use the "Call funcition..." statement to call them.
These two locks are executed in a special working process of the SAP system and are specially used for Lock management. It runs on a separate server, which is used to maintain the central lock table of the entire SAP system ).
There are two lock types:
1. Shared lock-read-only lock. When a user is reading data, other users are prevented from changing the data.
2. exclusive lock-write lock. When a user is modifying data, other users are prevented from changing the data.

7. Update FM
Update FM is divided into V1 and V2. Which update type will be executed first? Which mode (asynchronous, synchronous, or local) is used for each type of execution?
Answer: V1 has a higher priority than V2. Therefore, V1 has a higher priority than V2. The V1 execution mode can be asynchronous, synchronous, or local; V2 can only be asynchronous.

8. Modify Assistant)
What is a change assistant?
Answer: Modify assistant is a tool introduced in version 4.5 to simplify the update process. You can use the ABAP editor to trigger the modification Assistant, which records the modifications made to the system. The modification Assistant supports modification through the ABAP Editor, screen painter, menu painter, text element maintenance, function builder, and ABAP dictionary.

9: function module exit)
Which statement should be used in the SAP application when the function module exit is implemented?
Answer: Some SAP applications have function module exits, which allow users to add some features to the SAP program. You can search for "Call customer" to find whether a function module exit exists.

10. Change SAP (changing SAP)
List different methods for users to modify SAP standard functions.
Answer: SAP standard can be changed through personalization, customizing, modifications, enhancements, and custom ABAP programs. Examples of these methods are as follows:
Personalization-personalization technology includes creating variants, setting/obtaining parameters, and activity groups ).
Customizing -- is the most commonly used SAP tool (such as R/3 Reference Model and Implementation Guide) to change the SAP standard. It can be considered that mizmizing is necessary to implement R/3, which is usually executed by the functional team.
Enhancements is usually executed by the development team. The activities include dictionary enhancement, funciton module exits, menu and screen exit, and business add-ins (Badi ).
Custom ABAP program-it can work with SAP objects or custom development objects.
Modifications -- modifications are not recommended for SAP objects. Use sscr (SAP software change registry) to register all manual modifications to sap objects.

 

I. Add Fields
Which two methods are used to add fields to an SAP table?
Answer: The two methods are: append structure and custom include ). The append structure is created when a field is added to the end of the table. The custom include structure is specified by SAP developers so that users can create new fields.

Ii. Modifications)
In the SAP system, how does one define "modification? What are their impacts on the update?
Answer: Modification refers to changes made to the repository object published by SAP.
Modifications must be reviewed during the update period to determine whether new SAP objects should be used and whether further modification is required for future use.

Iii. Concepts of cluster tables and pool tables
Answer:
Pools and cluster Table; they are no longer common tables of various databases and cannot be directly accessed by databases. You can only use your own sap tools for direct access.
Transparent table:
Each transparent table has a corresponding physical table in the database. Physical table name and logical table in Data Dictionary
The name of the definition is consistent. All transactions and application data are stored in transparent tables.
Structure:
The structure does not have any data records in the database. Structure is used to define interfaces between programs or between programs and screens.
Additional structure:
A subset of the additional structure definition field, which belongs to another table or structure, but is used as a single
Unique object.
Storage table:
Storage tables can be used to store control data (such as screen sequence, program parameters, or temporary data ). Several Storage
Table store can be combined into a table database. This table library is consistent with a physical table library in the database. It contains groups
All records assigned to the database.
Cluster kekekey table:
Continuous text, such as documents, can be stored in cluster tables. Several cluster tables can be combined into a table cluster. For this
Table type. Several logical rows in different tables are combined into one physical record. This allows an object to be connected to
To store or access tables in a cluster, at least a portion of the keywords MUST match. Several
The cluster Table is stored in a corresponding table in the database.

4. Authorization object)
What is an authorization object? Which statement is used in the ABAP program for authorization check?
Answer: An authorization object is composed of a group of fields whose values are used for authorization checks. In the ABAP program, use the authority-check statement to perform authorization checks based on the authorization object. In the authority-check statement, all fields of the authorization object must be specified, but with one exception, you can use the dummy keyword to bypass the check of a field.
A maximum of 10 fields can be defined in an authorization object.

5. ABAP memory (ABAP memory) Switching
What are the two statements used for data exchange between programs using ABAP memory?
Answer: Export to memory ID is used to copy data to ABAP memory, and import from memory ID is used to copy data from ABAP memory to program.
Data exchanged between ABAP memory must be declared in both programs and contain the same data declaration. Test my signature
