SAP ABAP SYNTAX FOR ADD CORRESOPONDING

ADD-CORRESPONDING

Basic form

ADD-CORRESPONDING rec1 TO rec2.

Effect

Interprets rec1 and rec2 as field strings. If, for example, rec1 and rec2 are tables, executes the statement for their header lines.
Searches for all sub-fields which occur both in rec1 and rec2 and then, for all relevant field pairs corresponding to the sub-fields ni , generates statements of the form

ADD rec1-ni TO rec2-ni.
The other fields remain unchanged.

With complex structures, the complete names of the corresponding field
pairs must be textually identical.

Example

DATA: BEGIN OF VECTOR,

        X      TYPE I,

        Y      TYPE I,

        LENGTH TYPE I,

      END   OF VECTOR,

      BEGIN OF CIRCLE,

        VOLUME TYPE P

        Y      TYPE P,

        RADIUS TYPE I,

        X      TYPE I,

      END   OF CIRCLE.

...

ADD-CORRESPONDING VECTOR TO CIRCLE.

The sub-fields X and Y occur in both the field strings VECTOR and CIRCLE . Therefore, the ADD-CORRESPONDING statement is equivalent to both the following statements:

ADD VECTOR-X TO CIRCLE-X.

ADD VECTOR-Y TO CIRCLE-Y.
