Study Notes

Authority Check in ABAP

AUTHORITY-CHECK validates user permissions for specific objects and IDs with given field values.
Return code is 0 if the user is authorized for both 'CNTRY = 'DE' and 'ACTVT = '03'.
Program termination occurs if the user is not authorized for either condition.

Sorting Internal Tables

Standard tables can be sorted using SORT itab ASCENDING or SORT itab BY field1 field2.
Sorted tables can be sorted in descending order or by multiple fields.

Changing Row Contents in Internal Tables

Use the MODIFY statement to change the contents of a row in an internal table.

Access Control Object Clauses

Key clauses include WHERE (access conditions), DEFINE ROLE (specifies role name), and GRANT (identifies the data source).

ABAP Open SQL Statement Structure

The "INTO TABLE @gt flights" clause should be placed after defining the SELECT statement, specifically on line #8.

Predicate Condition for CAST

Use "IS INSTANCE OF" to ensure that the CAST will work correctly.

Logical Expression Evaluation

The order of operations is: NOT (highest priority), AND (medium priority), OR (lowest priority).

Database Table Definition

Essential components include Field list and Semantic table attributes.

CDS View Value Help Binding

Bind a CDS view to create value help in Data model view, Service definition, and Metadata extension.

Incomplete ABAP Types

Incomplete types include Character types (C) and Table types (T).

Integration Frameworks for ABAP Cloud Development

Frameworks available include OData services, Business events, and SOAP consumption.

Valid Statements in Given Code

Instance methods can be called using the newly created object or via referencing another instance.

RESTful Application Programming Object Creation Order

Objects are created in the order: Database table, Data model view, Service definition, and Service binding.

Core Data Services Benefits

CDS are preferred for their ability to avoid unnecessary data transfer and implement code pushdown.

Ensuring Uniqueness of a Semantic Key

Validation is the feature used for ensuring the semantic key's uniqueness.

Contextual Statements About Exceptions

Predefined names may exist within the code; references to previous exceptions and raising exceptions are actions performed.

Loop Control Variables in ABAP

The implicit loop counter during a DO...ENDDO loop is stored in sy-index.

Actions Causing Database Table Conversion

Changes to field labels or shortening domain lengths can cause indirect changes necessitating table conversion.
