INSPECT VERB IS USED TO REPLACE THE OCCURANCES OF SINGLE OR GROUP OF CHARACTERS IN DATA FIELD ?

  1. True

  2. False


Correct Option: A

AI Explanation

To answer this question, we need to understand the purpose of the INSPECT verb in programming.

The INSPECT verb is used in some programming languages, such as COBOL, to manipulate data fields. It allows you to search for specific characters or character groups within a data field and replace them with other characters.

Therefore, the statement "INSPECT verb is used to replace the occurrences of single or group of characters in a data field" is true.

The correct answer is A) True.

"OVERFLOW" AND "NOT ON OVERFLOW" OPTIONS CAN BE USED WITH COBOL STRING VERB?

  1. True

  2. False


Correct Option: A

The String moves data from Left to Right just like alphanumeric fields are moved ?

  1. True

  2. False


Correct Option: A

What is the Transaction code for Menu painter?

  1. SE51

  2. SE41

  3. SE38

  4. SE37


Correct Option: B

If a table does not have MANDT as part of the primary key,then it is considered as

  1. A structure

  2. Client Independent

  3. Invalid

  4. Client Dependent


Correct Option: B

AI Explanation

To answer this question, we need to understand the concept of primary keys and client dependency in database tables.

A primary key is a column or a set of columns in a table that uniquely identifies each row. It ensures that each row in the table is uniquely identifiable. The MANDT column is typically used as the primary key in SAP tables to identify the client.

In the given question, if a table does not have MANDT as part of the primary key, it means that it is not dependent on the client. This implies that the table is client independent.

Let's go through each option to understand why it is correct or incorrect:

Option A) A structure - This option is incorrect because a structure is a data type that does not have primary keys or dependencies.

Option B) Client Independent - This option is correct because if a table does not have MANDT as part of the primary key, it means that it is not dependent on the client. Hence, it is considered as client independent.

Option C) Invalid - This option is incorrect because the absence of MANDT as part of the primary key does not make the table invalid. It only indicates that the table is not dependent on the client.

Option D) Client Dependent - This option is incorrect because if a table does not have MANDT as part of the primary key, it means that it is not dependent on the client. Hence, it is considered as client independent.

The correct answer is B) Client Independent. This option is correct because if a table does not have MANDT as part of the primary key, it means that it is not dependent on the client.

In regard to CALL, which of the following is NOT a valid statement?

  1. CALL FUNCTION

  2. CALL SCREEN

  3. CALL TRANSACTION

  4. CALL PROGRAM


Correct Option: D
Explanation:

To understand this question, the user needs to know about CALL statements in programming. CALL statements are used to call other programs or functions within a program.

Now, let's go through each option and explain why it is right or wrong:

A. CALL FUNCTION: This is a valid statement in programming. It is used to call a specific function within a program.

B. CALL SCREEN: This is also a valid statement in programming. It is used to call a specific screen within a program.

C. CALL TRANSACTION: This is a valid statement in programming. It is used to call a specific transaction within a program.

D. CALL PROGRAM: This is NOT a valid statement in programming. The correct statement is CALL FUNCTION, which is used to call a specific function within a program.

Therefore, the answer is: D

Mapping of 1:1 relationship to database table is a

  1. Transparent

  2. View

  3. Cluster

  4. Pooled


Correct Option: A

AI Explanation

To answer this question, we need to understand the concept of mapping a 1:1 relationship to a database table.

Option A) Transparent - This option is correct because when we map a 1:1 relationship to a database table, it is done in a way that is transparent to the user. This means that the relationship is represented in a straightforward and easily understandable manner, without any additional complexity or confusion.

Option B) View - This option is incorrect because a view in a database is a virtual table that is derived from the data stored in one or more tables. It is not specifically related to mapping a 1:1 relationship.

Option C) Cluster - This option is incorrect because clustering in a database refers to the physical arrangement of data on disk to optimize data retrieval. It is not directly related to mapping a 1:1 relationship.

Option D) Pooled - This option is incorrect because pooling in a database refers to the concept of reusing resources (such as database connections) to improve performance. It is not directly related to mapping a 1:1 relationship.

The correct answer is A) Transparent. This option is correct because mapping a 1:1 relationship to a database table is done in a way that is transparent and easily understandable to the user.

What is the system field for the current date?

  1. SY-SDATE

  2. SY-DATE

  3. SY-DATUM

  4. SY-DATID


Correct Option: C

The SAP service that ensures data integrity by handling locking is called

  1. Enqueue/Dequeue

  2. Spool

  3. Update

  4. Dialog


Correct Option: A

AI Explanation

To answer this question, you need to understand the concept of data integrity and locking in the context of SAP.

The SAP service that ensures data integrity by handling locking is called Enqueue/Dequeue.

Option A) Enqueue/Dequeue - This option is correct. The Enqueue/Dequeue service in SAP is responsible for handling locking mechanisms to ensure data integrity. It manages the locking of resources, such as database entries or shared memory objects, to prevent conflicts and maintain consistency.

Option B) Spool - This option is incorrect. The Spool service in SAP is responsible for managing the output of reports and printing jobs.

Option C) Update - This option is incorrect. The Update service in SAP is responsible for managing the updating of database records.

Option D) Dialog - This option is incorrect. The Dialog service in SAP is responsible for managing the interaction between the user and the SAP system.

The correct answer is A) Enqueue/Dequeue. This option is correct because it accurately identifies the SAP service that ensures data integrity by handling locking.

Which keyword adds a line anywhere within an internal table?

  1. insert

  2. append

  3. add

  4. modify


Correct Option: A

AI Explanation

To answer this question, you need to understand how to manipulate internal tables in ABAP.

Option A) insert - This option is correct because the "insert" keyword is used to add a line anywhere within an internal table. It allows you to specify the position where the line should be inserted.

Option B) append - This option is incorrect because the "append" keyword is used to add a line to the end of an internal table. It does not allow you to specify the position of the line.

Option C) add - This option is incorrect because the "add" keyword is not used to add a line within an internal table. It is used for arithmetic operations.

Option D) modify - This option is incorrect because the "modify" keyword is used to modify existing lines in an internal table, not to add new lines.

The correct answer is A) insert. This option is correct because it is the keyword used to add a line anywhere within an internal table.
