ABAP_SYNTAX_OBS
ADD-CORRESPONDING struc1 TO struc2.
SUBTRACT-CORRESPONDING struc1 FROM struc2.
MULTIPLY-CORRESPONDING struc1 BY struc2.
DIVIDE-CORRESPONDING struc1 BY struc2.

What does it do?
These statements, which are forbidden in classes, add, subtract, multiply, or divide structures by component. Structures must be specified for struc1 and struc2 . All identically named components in struc1 and struct2 are processed in pairs and the result is assigned to the respective component of struct2.
The names are compared, as in the statement MOVE-CORRESPONDING. For each identically named component pair comp, the statement

ADD struc1-comp TO struc2-comp.

SUBTRACT struc1-comp FROM struc2-comp.

MULTIPLY struc1-comp BY struc2-comp.

DIVIDE struc1-comp BY struc2-comp.
is executed internally, and the appropriate conversions are performed, if necessary. In complex structures, the names of the field pairs in question must be completely identical at all hierarchical levels.



Latest notes:
These statements are error-prone because, particularly in complex structures, it is not easy to check that identically named components have the data type and content necessary for a numeric operation.

Example ABAP Coding

The components x and y occur in both structures and are added. After the addition, the results are in struc2-x and struc2-y.
