Dear Manish,
1- Remittance transfer is when a emigrant who works in KSA for example want to send money to there home land, they go to foreign currency exchange company who operate remittance transfer to send the money to the other country, my question is in which area it's handled in SAP TRM
2- regarding the second question, i already made the link between the business partner and the on time customer but still it needs to be authorized in TBI6 on the financial instrument which he will use and it shows error when changing the Business partner as it has no name or master data.
Thanks and Regards,
Ahmed Samir
