C_ABAPD_2507 Exam Questions & Answers

The FIND function in ABAP searches for a substring (sub) inside a string (val) and returns the offset (position) if found, or 0 if not found.

Let's evaluate Option A:

find( val = 'FIND Found found' sub = 'F' occ = -2 CASE = abap_true )

occ = -2: Searches for the second-last occurrence.

CASE = abap_true: Enforces case-sensitive search.

The string contains:

'FIND' matches 'F' (1st occurrence)

'Found' matches 'F' (2nd occurrence)

'found' does not match because of lowercase 'f' and case-sensitive flag.

So, valid case-sensitive matches for 'F' are:

1st: 'FIND'

2nd: 'Found'

Thus, the second-last occurrence is 'FIND'.

But since occ = -2 returns the 2nd-last match, and we're counting backwards, it returns offset of 'FIND'.

Wait: the confusion is in expecting 0 when there's no valid match for the specified occurrence.

But actually:

Option A does return 0 because occ = -2 expects at least 2 valid case-sensitive matches, and:

'Found' contains 'F' match

'FIND' contains 'F' match

So there are two matches.

BUT, occ = -2 is a reverse index.

First-last: 'Found'

Second-last: 'FIND'

It should return match offset for 'FIND' = 1 (NOT 0)

So, correction: A does NOT return 0.

A Recommended to define attributes for message placeholders.

C Inheriting from cx_static_check enforces compile-time checks to ensure exceptions are handled.

E Implementing if_t100_message allows integration with message classes.

B Misleading, design-time warning is about handling, not raising.

D Not a recommended practice in ABAP Cloud (system classes are not extendable).

Behavior Definition (BDEF) is where read-only, mandatory, and transactional rules are enforced across all RAP applications.

Projection view restricts fields per app, not globally.

Metadata extension UI annotations only.

Service definition defines exposure, not behavior.

Therefore, setting field read-only in the behavior definition enforces it globally across all RAP BO usages.

Encapsulation in ABAP OO and ABAP Cloud ensures that internal object details are hidden from outside consumers.

A . Attributes can be changed through public methods Correct, because controlled access is provided through getter/setter or other methods.

B . Attributes can be changed by the client program directly Incorrect, this violates encapsulation.

C . Attributes cannot be changed Incorrect, they can be changed, but only via allowed mechanisms.

D . Attributes can only be changed by the class itself Correct, ensuring business logic consistency.

This aligns with RAP behavior definitions (BDEF) where internal attributes are encapsulated and only manipulated through behavior implementation methods.

In RAP, changes to business object data are performed using Entity Manipulation Language (EML).

It provides ABAP statements such as READ ENTITIES, MODIFY ENTITIES, CREATE, and DELETE for RAP BOs.

EML is the cloud-compliant equivalent of SQL DML (insert/update/delete) but tailored to RAP's transactional consistency.
