    Study Notes

    Assignment and Data Declarations

    • gv_target can be assigned without truncation or rounding if gv_source is of type string and gv_target is of type c.
    • gv_target can be assigned without truncation or rounding if gv_source is of type d and gv_target is of type string.
    • gv_target can be assigned without truncation or rounding if gv_source is of type p length 8 decimals 3 and gv_target is of type p length 16 decimals 2.

    RESTful Application Programming

    • Validation is a feature used to ensure the uniqueness of a semantic key.
    • The EML statement that retrieves an object is Get entity.

    ABAP SQL

    • An alias can be assigned to a field from a field list.
    • An alias can be assigned to a group criterion from a group by clause.

    Inheritance in ABAP

    • To redefine a component of a superclass in a subclass, add the REDEFINITION clause to the component in the subclass.
    • The redefined component must be implemented in the subclass.

    Access Controls with CDS Views

    • Access Controls with CDS Views ensure that only data corresponding to the user's authorization is transferred from the database to the application layer.
    • Access Controls with CDS Views eliminate the need to implement AUTHORITY CHECK statements.

    Interfaces in ABAP

    • A class can use an interface.
    • A class can implement an interface.
    • In a class, an interface method can be named if1-ml.

    Exception Handling

    • RAISE EXCEPTION TYPE can be used to raise an exception.
    • A dictionary structure can be used to pass parameters to an exception.
    • The code creates an exception object and raises an exception.

    Join Conditions

    • ON conditions can be used to specify join conditions.
    • ON $projection Carrier = _Source2.Carrier is a valid join condition.
    • ON Z_Sourcel.carrier_id = _Source2.carrier_id is a valid join condition.

    ABAP Types

    • String is an incomplete ABAP type.
    • P is an incomplete ABAP type.

    CDS Views

    • They store information in two dimensions.
    • They can have key fields.

    Class Definition

    • A class can be defined with a method.
    • A method can call a function.

    Internal Tables

    • Target_itab = VALUE #( FOR row IN source_itab ( Field1 = row-field1 Field2 = row-fiel2 Fieldn = row-fieldn ) ) is a valid statement.
    • FOR defines a loop that runs over the content of source_itab.
    • row is only visible within the loop.

    Function Calls

    • Count_any_of returns the number of occurrences of a substring.
    • Count returns the number of characters in a string.
    • Find_any_of returns the position of the first occurrence of a substring.

    Data Modification

    • MODIFY TABLE can be used to change the contents of a row in an internal table.

    RESTful Application Programming

    • A Data model view can be used to organize the display of fields in an app.
    • A Projection view can be used to organize the display of fields in an app.

    Exception Patterns

    • Assigning a date value to a decimal variable raises an exception.
    • Assigning a string value to a char variable raises an exception.
    • Dividing by zero raises an exception.

    Internal Tables

    • A hashed internal table allows unique and non-unique keys.
    • A sorted internal table allows unique and non-unique keys.

    Secondary Keys

    • Secondary keys must be chosen explicitly when reading from an internal table.
    • Multiple secondary keys are allowed for any kind of internal table.
    • Hashed secondary keys do not have to be unique.

    Core Data Services

    • They implement code pushdown.
    • They avoid data transfer completely.

    ABAP SQL

    • The INTO clause allows the use of inline declarations.
    • The INTO CORRESPONDING FIELDS OF clause allows the use of inline declarations.
    • The FIELDS clause allows the use of inline declarations.
