Hi Vijay.
The document is complete as for its title. Its not, nor was intended to be, the FPY1 cookbook.
There are several customization areas that you would have to go through in order to have the payment run fully functional:
- business partner bank accounts (which you can do after you have entered needed bank details and settings)
- incoming and outgoing payment methods (once defined, you need to assign them to the contract accounts)
- clearing accounts and accounts for payment program (again, depending on your business scenario, you might need to use the clearing accounts in order to correctly post clearing and payment documents; you need to have those accounts open in your chart of accounts)
- mark documents for repayment or create documents to retrieve payment for (depending on your type of payment run: incoming or outgoing, you need to have such documents / open items; you could also check the payment terms configuration before doing this)
- payment medium and DMEE files (you said you already covered that part)
- payment run itself (there are sets of parameters that you might need to check in order to get the correct payment run going)
Hope this helps.
