My requirement is i have a sapscript "F110_IN_AVIS" (Driver program:RFF0EDI1 This is a standard sap driver program)and it should be converted to Smartform with all the windows as it was present in sapscript. I have migrated the sapscript to smartform (as you all know that only the layout will be copied and not the logic). Now how to identify the table names and the corresponding field names related to each of these windows. Kindly suggest how to proceed with the driver program. Also Kindly send any document or any sample program for Payment remittance advice to vendor. Full pints will be rewarded to valuable answers. Thanks in advance.
