問題 #65
For the assignment, gv_target = gv_source.
which of the following data declarations will always work without truncation or rounding? Note: There are 2 correct answers to this question.

答案:B,C

解題說明:
The data declarations that will always work without truncation or rounding for the assignment gv_target = gv_source are B and C. This is because the target data type string is a variable-length character type that can hold any character string, including those of data types c (fixed-length character) and d (date). The assignment of a character or date value to a string variable will not cause any loss of information or precision, as the string variable will adjust its length to match the source value12.
You cannot do any of the following:
A . DATA gv_source TYPE string, to DATA gv_target TYPE c.: This data declaration may cause truncation for the assignment gv_target = gv_source. This is because the target data type c is a fixed-length character type that has a predefined length. If the source value of type string is longer than the target length of type c, the source value will be truncated on the right to fit the target length12.
D . DATA gv_source TYPE p LENGTH 8 DECIMALS 3. to DATA gv_target TYPE p LENGTH 16 DECIMALS 2.: This data declaration may cause rounding for the assignment gv_target = gv_source. This is because the target data type p is a packed decimal type that has a predefined length and number of decimal places. If the source value of type p has more decimal places than the target type p, the source value will be rounded to the target number of decimal places12.


問題 #66
What RESTful Application Programming feature is used to ensure the uniqueness of a semantic key?

答案:C

解題說明:
The RESTful Application Programming feature that is used to ensure the uniqueness of a semantic key is determination. A determination is a type of behavior implementation that defines a logic that is executed automatically when certain events occur, such as create, update, delete, or activate. A determination can be used to calculate or derive values for certain fields, such as semantic keys, based on other fields or external sources. A determination can also be used to check the uniqueness of a semantic key by comparing it with the existing values in the database or the transaction buffer. A determination can use the ABAP SQL or the EML syntax to access and manipulate data. A determination can be defined using the DETERMINE action clause in the behavior definition of a CDS view entity or a projection view. A determination can also be annotated with the @ObjectModel.determination annotation to specify the event, the timing, and the scope of the determination12 The other RESTful Application Programming features are not used to ensure the uniqueness of a semantic key, but have different purposes and effects. These features are:
Validation: A validation is a type of behavior implementation that defines a logic that is executed automatically when certain events occur, such as create, update, delete, or activate. A validation can be used to check the consistency and correctness of the data, such as mandatory fields, data types, value ranges, or business rules. A validation can use the ABAP SQL or the EML syntax to access and manipulate data. A validation can be defined using the VALIDATE action clause in the behavior definition of a CDS view entity or a projection view. A validation can also be annotated with the @ObjectModel.validation annotation to specify the event, the timing, and the scope of the validation12 Action: An action is a type of behavior implementation that defines a logic that is executed explicitly by the user or the application. An action can be used to perform a specific business operation, such as creating, updating, deleting, or activating an entity instance, or triggering a workflow or a notification. An action can use the ABAP SQL or the EML syntax to access and manipulate data. An action can be defined using the ACTION clause in the behavior definition of a CDS view entity or a projection view. An action can also be annotated with the @ObjectModel.action annotation to specify the name, the description, the parameters, and the visibility of the action12


問題 #67
How do you make class sub1 a subclass of class super1?

答案:C

解題說明:
Comprehensive and Detailed Explanation From Exact Extract:
In ABAP, inheritance is declared in the class DEFINITION using the keyword INHERITING FROM. The RAP documentation shows this exact syntax in multiple class definitions, for example:
* "CLASS lcl_local_event_consumption DEFINITION INHERITING FROM
cl_abap_behavior_event_handler." This proves the inheritance clause belongs to the DEFINITION section, not the IMPLEMENTATION, and uses the form INHERITING FROM <superclass>.(Back- End Developer - ABAP Cloud study areas: RAP handler/event classes use standard ABAP OO rules; architecture shows inheritance declared in DEFINITION with INHERITING FROM.)


問題 #68
Which function call returns 0?

答案:A

解題說明:
The function find_any_not_of returns the position of the first character in the string val that is not contained in the string sub. If no such character is found, the function returns 0. In this case, the string val contains only the characters A, B, and a, which are all contained in the string sub, so the function returns 0. The other functions return positive values, as follows:
Count_any_of returns the number of occurrences of any character in the string sub within the string val. In this case, it returns 8, since there are 8 A's and B's in val.
Count returns the number of occurrences of the string sub within the string val. In this case, it returns 2, since there are 2 AB's in val.
find_any_of returns the position of the first character in the string val that is contained in the string sub. In this case, it returns 1, since the first character A is in sub. Reference: String Functions - ABAP Keyword Documentation, Examples of String Functions - ABAP Keyword Documentation


問題 #69
What are some features of ABAP SQL?
Note: There are 2 correct answers to this question.

答案:A,D

解題說明:
Comprehensive and Detailed Explanation From Exact Extract:
ABAP SQL (also known as Open SQL):
* Is fully integrated in the ABAP language and supports embedded use with host variables, making Option B correct.
* Is first processed by the ABAP Database Interface, which translates Open SQL into the database- specific native SQL. Hence, Option A is also correct.
* Option C is incorrect because ABAP SQL is not directly executed on HANA or any database; it is interpreted and adapted by the ABAP layer.
* Option D is incorrect because ABAP SQL is not restricted to HANA; it is database-agnostic and works across different supported DBs.
Reference: ABAP CDS Development User Guide, section 2.2 - ABAP SQL processing and database abstraction concepts.
