ADD-CORRESPONDING (ABAP Keyword) introduction & Details

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.

Note
All fields with the same name are added,
whether numeric or not. The same conversions are performed as with ADD and
similar runtime errors to those possible with ADD can also occur.
