Hi
Have you maintained the clearing account configuratiion for payment request? the location in Spro is as below. Also do you see whether the system states the payment request crated in the posting log in TBB1, which normally is the case?
IMG: Financial Supply Chain Management è Treasury and Risk Management è Transaction Manager è General Settings è Payment Management è Payment Requests èDefine Clearing Account for Payment Requests
Hope that this helps.
Kind regards
