Hi,

i am working on script

i need to subtract two values (MSEG-ERFMG - MSEG-LSMNG)

i am passing these variables in the perform

PERFORM GET_MAT_DESCREPANCY IN PROGRAM ZMM_SUB_GRN_REJPRINT

USING &MSEG-ERFMG&

USING &MSEG-LSMNG&

CHANGING &P_DIS&

ENDPERFORM

and in the form i am using

FORM GET_MAT_DESCREPANCY TABLES T_IN STRUCTURE ITCSY T_OUT STRUCTURE ITCSY.

READ TABLE T_IN WITH KEY NAME = 'MSEG-ERFMG'.

MOVE T_IN-VALUE TO P_ERFMG.

i want to subract MSEG-ERFMG - MSEG-LSMNG values

Hi Divya,

I assume you are getting errors because of using "," as a decimal sign. You may try

translate t_in-value using ',.. '.
condense t_in-value no-gaps.
move t_in-value to p_erfmg.

I hope this helps. Best regards,
