Hi friends,

Can we change two fields with one variable in subroutine pool...

what I mean is......

/:FORM ZFORM IN PROGRAM ZPROG

/:USING &VAR&

/:CHANGING &ABC&

/:CHANGING &CDE&

/:ENDPERFORM.

Can I call like this.......

Yes because you are passing one variable to Form Subroutine

Use this type of declaration

FORM GET_BARCODE TABLES IN_PAR STUCTURE ITCSY

OUT_PAR STRUCTURE ITCSY.

Hi,

No need to write CHANGING for two times, use the key work for single time, using the same key work in FORM is a syntax error.

ex:

FORM ZFORM IN PROGRAM ZPROG

USING V1

CHANGING V2 V3.

ENDFORM.

Is your question answered.

hi,

You can use this. You can include two or maor CHANGING parameters.

In the Called Sub routine there parametrs are stored in a Internal TAble and Return the Value in the internal table so we can give fields like this.

Hope this will help.

Hi,

It will be

/:PERFORM ZFORM IN PROGRAM ZPROG

/:USING &VAR&

/:CHANGING &ABC&

/:CHANGING &CDE&

/:ENDPERFORM.

There Is no such rule for Changing parameters.

Hosmath,

Please check this link

http://www.sap-basis-abap.com/abap/how-to-call-a-subroutine-form-sapscripts.htm

Yes you can change as many fields u want using the subroutine .

/:PERFORM ZFORM IN PROGRAM ZPROG
/:USING &VAR&
/:CHANGING &ASD&
/:CHANGING &ZXC&
/:CHANGING &QWE&
/:CHANGING &CDE&
/:CHANGING &TYU&
/:ENDPERFORM.

CHANGING is nothing but you are importing the values from the subroutine.

You are passing the value VAR and you are importing the other values.

Best reagrds,
