Hi Abdul,
When you set the parameter in F110, please go to the Free Selection Tab. Then in the field name select the option OTHER. It will give you three options
1.Document
2. Vendor Master Record
3. Cust. Master Rescord
Select the option Document and then from the list select the option Payment Method. Now it will be shown in the Field Name field. Then in the Values field enter the payment method which should not be considered. Then check the box Exclude Values. Now create the proposal and check.
Please let me know the result.
Regards,
Pintu
