SAP Script : Calculations with text elements

[Former Member]

Dear All,

How can I do calucations in SAP Script.

Actually I have 2 text elements Total and tax. And I would like to display Sub Total which is Total - Tax.

I wonder how can I do that directely in SAP Script without Editing printprogram

Thank you for your inputs.

You cannot do any calculation in script.

Why you want to do in the form instead of print program.

If the print program is standard and if you decided not to change that program you can call a subroutine from the

form, In that form u can do the necessary calculations.

Hope this helps..

Thanks,

Hi...

On your SAP script write:

/: PERFORM subrutine IN PROGRAM Zprogram

/: USING &PAR1&

/: CHANGING &PAR2&

/: ENDPERFORM

PS: You can use as many USING AND CHANGING as you need.

And the zprogram goes;

FORM subrutine TABLES t_in STRUCTURE itcsy

t_out STRUCTURE itcsy.

data: par1 type n.

• Read the value on PAR1

READ TABLE t_in WITH KEY 'PAR1'.

CHECK sy-subrc = 0.

PAR1 = t_IN-value.

• DO WHATEVER YOU NEED TO DO

ADD 1 TO PAR1.

....

• SEND THE VALUES BACK

READ TABLE t_OUT WITH KEY 'PAR2'.

t_sal-value = PAR1 .

MODIFY t_OUT INDEX sy-tabix.

ENDFORM.
