Vera’s Day

Always use variable when trying to modify table, or else you’ll get randomly unexpected results.. well, at least that’s what happened to me with SAP/R3 4.6D.

For example, you’ve got a transparent table you wish to manipulate named: ZTXXX.
Create a variable named WA_ZTXXX.

DATA: WA_ZTXXX LIKE ZTXXX.

CLEAR WA_ZTXXX.
SELECT SINGLE * INTO WA_ZTXXX
FROM ZTXXX
WHERE [CONDITION].

IF SY-SUBRC EQ 0.
WA_ZTXXX-FIELD1 = ‘Blabla’.
WA_ZTXXX-FIELD2 = ‘Blibli’.

MODIFY ZTXXX FROM WA_ZTXXX.
ENDIF.
