Hi Sara,
I am not in front of the system. We do not link the bank account to PTRA, In OT83, please complete all the steps, from accounts symbols, masking, posting rule, posting rules asignment, transaction type.
Mostly particularly, please ensure you have completed the last folder in OT83, where you maintain the bank key. Hope you must have completed.
All the configuration is within OT83 only.
Best Regards,
Ravi
