Purchase Order SAPscript - Looping problem.

Question

Dear Friends,
I am using a PO Z-form which is a copy of MEDRUCK and print program is Standard SAPLMEDRUCK Program.
I have got a Scenario something like this.
I have to display some classification details of material ( from material master ) in PO.
A material will have 2 or 3 Classes, Each class has got some details.
I have to loop for each class and display the details.
Since I am using Standard Print Program, I Can't Change that.
Is there any workaround method for the above requirement.
Regards,
Hari.

Hi Hari,
             There is not need to use that WRITE_FORM FM,
Instead write the PERFORM statement in the window where you need to display the classification values and after immediately give the variables which holds the classification values.
Example
/:PERFORM GET_COMCODE IN PROGRAM ZM_RFQ_REJECTION
/:USING &EKKO-BUKRS&
/:USING &EKKO-SPRAS&
/:CHANGING &SADR-NAME1&
/:CHANGING &SADR-NAME2&
/:CHANGING &SADR-NAME3&
/:CHANGING &SADR-PSTLZ&
/:CHANGING &SADR-NAME4&
/:ENDPERFORM
B &SADR-NAME1&,, &SADR-NAME2&,,&SADR-NAME3&,, &SADR-PSTLZ&,, &SADR-NAME4&
as in above example you pass the Material no in USING field and in CHANGING fields DEFINE variables for classification and pass
