SUBTRACT-CORRESPONDING is a keyword used in SAP ABAP programming.This tutorial covers its introduction & syntax details.
SUBTRACT-CORRESPONDING rec1 FROM rec2.
rec1 and rec2 as field strings. If, for example, rec1 and rec2 are
tables, executes the statement for their header lines.
for all sub-fields which occur both in rec1 and rec2 and then
generates, for all relevant field pairs corresponding to the component
fields ni , statements of the form
SUBTRACT rec1-ni FROM rec2-ni.
The other fields remain unchanged.
With complex structures, the full names of the field pairs must be identical.
DATA: BEGIN OF PERSON,
NAME(20) VALUE ‘Paul’,
MONEY TYPE I VALUE 5000,
END OF PERSON,
BEGIN OF PURCHASES OCCURS 10,
MONEY TYPE I,
END OF PURCHASES.
PURCHASES-PRODUCT = ‘Table’.
PURCHASES-MONEY = 100.
PURCHASES-PRODUCT = ‘Chair’.
PURCHASES-MONEY = 70.
LOOP AT PURCHASES.
SUBTRACT-CORRESPONDING PURCHASES FROM PERSON.
The value of PERSON-MONEY is now 4830. The above SUBTRACT-CORRESPONDING statement (executed twice here) is equivalent to:
SUBTRACT PURCHASES-MONEY FROM PERSON-MONEY.
fields of the same name are subtracted, whether they are numeric or
not. Here, the conversions performed are the same as with SUBTRACT and
the same runtime errors can occur.
