Calculating difference in SAP Script

[Former Member]

Hello All,

I have 2 variables &REGUP-WRBTR& and &REGUP-SKNTO& passed to sap script from print program. I want to calculate thier difference in the script and display the value. I am using.

/: DEFINE &NET_AMOUNT& = &REGUP-WRBTR& - &REGUP-SKNTO&

This is not working. Could anyone please suggest how to solve this?

Hi Indrajit,

try it

/: DEFINE &NET_AMOUNT&

&NET_AMOUNT& = &REGUP-WRBTR& - &REGUP-SKNTO&

You only have limited commands in SAPscript, and they do not include arithmatic.

You either have to perform the subtraction in your print program, or call a subroutine from your SAPscript.

Hi indrajit.

You cannot perform any arithmetic operations in Layout set text elements.

But we can acheive this using the PERFORM command.

Eg:

In the window :

/: DEFINE &NET_AMOUNT& = '0'

/: PERFORM F_CALC_DIFF IN PROGRAM ZREP01

/: USING &REGUP-WRBTR&

/: USING &REGUP-SKNTO&

/: CHANGING &NET_AMOUNT&

/: ENDPERFORM

• Net amount = &NET_AMOUNT&

In the program ZREP01 define the Subroutine:

FORM F_CALC_DIFF TABLES INTAB STRUCTURE ITCSY

OUTTAB STRUCTURE ITCSY.

DATA : V1 TYPE REGUP-WRBTR,

V2 TYPE REGUP-WRBTR,

V3 TYPE REGUP-WRBTR.

READ TABLE INTAB INDEX 1.

V1 = INTAB-VALUE.

READ TABLE INTAB INDEX 2.

V2 = INTAB-VALUE.

V3 = V1 - V2.

WRITE V3 TO OUTTAB-VALUE LEFT-JUSTIFIED.

MODIFY OUTTAB INDEX 1.

ENDFORM.

This will give you the solution.
