Please help me in this regard. please seee the code ..as I am a new-bie, I might making some silly mistake. Please look at this problem and suggest me.
I have been suggested by my friend to use ..Move but I am not sure ..how to do that. Please kindly spare some time.
/: PERFORM GET_SUBTOTAL IN PROGRAM ZGET_SUBTOTAL
/: USING &BSEG-WRBTR&
/: USING &BSEG-WMWST&
/: CHANGING &S_SUBTOTAL&
FORM GET_SUBTOTAL TABLES INT_COND STRUCTURE ITCSY
OUT_COND STRUCTURE ITCSY.
DATA : W_WRBTR TYPE BSEG-WRBTR, " Total
W_WMWST TYPE BSEG-WMWST. " Tax
READ TABLE INT_COND INDEX 1.
W_WRBTR = INT_COND-VALUE.
READ TABLE INT_COND INDEX 2.
W_WMWST = INT_COND-VALUE.
OUT_COND-NAME = 'S_SUBTOTAL'.
OUT_COND-VALUE = W_WRBTR - W_WMWST.
MODIFY OUT_COND INDEX 1.
