QUESTION: 12

What are some features of a unique secondary key?
Note: There are 2 correct answers to this question.

It is created when a table is filled.
It is updated when the modified table is read again.
It is created with the first read access of a table.
It is updated when the table is modified.

Answer(s): C,D

Explanation:

A unique secondary key is a type of secondary key that ensures that the key combination of all the rows in a table is unique. A unique secondary key has two purposes: firstly, to speed up access to the table, and secondly, to enforce data integrity.
It is created with the first read access of a table: This is true. A unique secondary key is created when an internal table is filled for the first time using the statement READ TABLE or a similar statement. The system assigns a name and an index to each row of the table based on the key fields.
It is updated when the modified table is read again: This is false. A unique secondary key does not need to be updated when the internal table content changes, because it already ensures data uniqueness. The system uses a lazy update strategy for non-unique secondary keys, which means that it delays updating them until they are actually accessed.
You cannot do any of the following:
It is created when a table is filled: This is false. As explained above, a unique secondary key is created only with the first read access of a table.
It is updated when the modified table is read again: This is false. As explained above, a unique secondary key does not need to be updated when the internal table content changes.

QUESTION: 13

Refer to the exhibit.

Which of the following types are permitted to be used for <source> on line #4?
Note: There are 2 correct answers to this question.

A database table from the ABAP Dictionary
A CDS DDIC-based view
An external view from the ABAP Dictionary
A database view from the ABAP Dictionary

Answer(s): A,B

Explanation:

The <source> clause in the CDS View Entity Data Definition can be used to specify the data source for the view entity. The <source> clause can accept different types of data sources, depending on the type of the view entity.
A database table from the ABAP Dictionary: This is a valid type of data source for a CDS View Entity Data Definition. A database table from the ABAP Dictionary is a table that is defined in the ABAP Dictionary using the keyword TABLE or TABLE OF. The name of the database table must be unique within its namespace and must not contain any special characters. A CDS DDIC-based view: This is also a valid type of data source for a CDS View Entity Data Definition. A CDS DDIC-based view is a view that is defined in the Core Data Services using the keyword DEFINE VIEW ENTITY. The name of the CDS DDIC-based view must be unique within its namespace and must not contain any special characters.
You cannot do any of the following:
An external view from the ABAP Dictionary: This is not a valid type of data source for a CDS View Entity Data Definition. An external view from the ABAP Dictionary is a view that is defined in an external application using any language supported by SAP, such as SQL, PL/SQL, or Java. The name of the external view must be unique within its namespace and must not contain any special characters.
A database view from the ABAP Dictionary: This is not a valid type of data source for a CDS View Entity Data Definition. A database view from the ABAP Dictionary is a view that is defined in an external application using any language supported by SAP, such as SQL, PL/SQL, or Java. The name of the database view must be unique within its namespace and must not contain any special characters.

QUESTION: 14

When processing a loop with the statement DO... ENDDO, what system variable contains the implicit loop counter?

sy-linno
sy-labix
sy-subrc
sy-index

Answer(s): D

Explanation:

When processing a loop with the statement DO... ENDDO, the system variable that contains the implicit loop counter is sy-index. The loop counter is a numeric value that indicates how many times the loop has been executed. The loop counter is initialized to 1 before the first execution of the loop and is incremented by 1 after each execution. The loop counter can be used to control the number of loop iterations or to access the loop elements by index. The loop counter can also be accessed or modified within the loop body, but this is not recommended as it may cause unexpected results or errors.
For example, the following code snippet uses the loop counter sy-index to display the numbers from 1 to 10:
DO 10 TIMES. WRITE: / sy-index. ENDDO.
The output of this code is:

1 2 3 4 5 6 7 8 9 10

QUESTION: 15

Which patterns raise an exception?
Note: There are 3 correct answers to this question.

DATA: gv_target TYPE p DECIMALS 2. CONSTANTS: go intl TYPE i VALUE 3. gv_target -U EXACT (2 gcojntl).
DATA: gv_target TYPE string. CONSTANTS: gco_string TYPE LENGTH 16 VALUE 0123456789ABCDEF*. gv_target = EXACT # gco_string+5 (5) ).
DATA: gv_target TYPE c LENGTH 5. V CONSTANTS: ECO string TYPE string VALUE 0123456789ABCDEF". gv_target - EXACT (gco_string + 5 (6) ).
DATA: Ev target TYPE p DECIMALS 3. CONSTANTS: gcojntl TYPE i VALUE 2. Ev_target -U EXACT #2 / gcojntl ).
DATA: gv_target TYPE d. s/ CONSTANTS: gco_date TYPE d VALUE '20331233*. gv_target EXACT ( geo_date).

Answer(s): A,C,E

Explanation:

The patterns that raise an exception are those that use the constructor operator EXACT to perform a lossless assignment or calculation, but the result cannot be converted to the target data type without data loss. The following are the explanations for each pattern:
A: This pattern raises the exception CX_SY_CONVERSION_LOST because the result of the calculation 2 * 3 is 6, which cannot be assigned to a packed number with two decimal places without losing the integer part. The operator -U is used to perform a lossless calculation with the calculation type decfloat.
B: This pattern does not raise an exception because the result of the substring expression gco_string+5(5) is `6789A', which can be assigned to a string without data loss. The operator EXACT # is used to perform a lossless assignment with the data type of the argument.
C: This pattern raises the exception CX_SY_CONVERSION_LOST because the result of the substring expression gco_string+5(6) is `6789AB', which cannot be assigned to a character field with length 5 without losing the last character. The operator EXACT is used to perform a lossless assignment with the data type of the target field.
D: This pattern does not raise an exception because the result of the calculation 2 / 2 is 1, which can be assigned to a packed number with three decimal places without data loss. The operator -U is used to perform a lossless calculation with the calculation type decfloat.
E: This pattern raises the exception CX_SY_CONVERSION_ERROR because the constant gco_date contains an invalid value `20331233' for a date data type, which cannot be converted to a valid date. The operator EXACT is used to perform a lossless assignment with the data type of the target field.
