SAP ABAP — Control Statement

Case Control Statement

The CASE control statement is used when we need to compare two or more fields.

No logical expressions can be used for the <field> field.

The field strings used in the CASE statement are treated as type C variable.

CASE VARIABLE.
WHEN VALUE1.
………
WHEN VALUE2.
………
WHEN OTHERS.
………
ENDCASE.
DO.

Example :

REPORT Z_ABAP_DEVELOPER_TEST.

DATA: A TYPE I VALUE 5.

CASE A.
WHEN 3.
WRITE:/ A, ‘Equals’, 3.
WHEN 4.
WRITE:/ A, ‘Equals’, 4.
WHEN 5.
WRITE:/ A, ‘Equals’, 5.
WHEN OTHERS.
WRITE:/ ‘Not Found’.
ENDCASE.
