Hi
Your question is not clear.
I hope your requirement is as below:
May be it's relating to Accounts Payable
Invoice created in SAP - details of the invoice sends to the 3rd party system - 3rd party makes the payment.
I will explain the step wise solution for the above scenario:
1) Invoice created in SAP - It will update the Tables: BKPF, BSEG, BSIK
2) Do the payment for the Invoice posted in step-1 - It will update the Tables: BKPF, BSEG, BSAK : It is required otherwise, always the vendor balances shows red, that means unpaid. Here, the payment can be made using different payment method based on availability of the vendor bank details.
3) Create an outbound program, which will send the details of the payment to the 3rd Party: Details should include vendor name, vendor address details, vendor bank details, etc. Look up the Tables: LFA1, LFB1, LFBK, BSAK, BKPF.
4) 3rd party will pay the amount based on the payment method (check / bk transfer).
