MULTIPLY-CORRESPONDING (ABAP Keyword)

MULTIPLY-CORRESPONDING is a keyword used in SAP ABAP programming.This tutorial covers its introduction & syntax details.

MULTIPLY-CORRESPONDING

Basic form
MULTIPLY-CORRESPONDING rec1 BY 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 generates,
for all field pairs corresponding to the sub-fields ni , statements of
the form

MULTIPLY rec1-ni BY rec2-ni.

The other fields remain unchanged.

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

Example

DATA: BEGIN OF MONEY,
VALUE_IN(20) VALUE ‘German marks’.
USA TYPE I VALUE 100,
FRG TYPE I VALUE 200,
AUT TYPE I VALUE 300,
END OF MONEY,
BEGIN OF CHANGE,
DESCRIPTION(30)
VALUE ‘DM to national currency’.
USA TYPE F VALUE ‘0.6667’,
FRG TYPE F VALUE ‘1.0’,
AUT TYPE F VALUE ‘7.0’,
END OF CHANGE.
MULTIPLY-CORRESPONDING MONEY BY CHANGE.
MONEY-VALUE_IN = ‘National currency’.

The above MULTIPLY-CORRESPONDING statement is equivalent to the following three statements:

MULTIPLY MONEY-USA BY CHANGE-USA.
MULTIPLY MONEY-FRG BY CHANGE-FRG.
MULTIPLY MONEY-AUT BY CHANGE-AUT.

Note
All
fields with identical names are multiplied, whether numeric or not. The
conversions performed are similar to those for MULTIPLY and the same
runtime errors can also occur.
