Same bank Account in Multiple Sites

Hi all,

I have created a new supplier with two supplier sites, Each site has been assigned to 2 Operating Units.

I am trying to add/create supplier bank details at supplier site level.

After adding the bank details and when i hit save/apply button i get the below error.

1. The external bank account already exists
2. One of the assignment of this bank account is related to operating unit (XX Operating Unit).

Please share some suggestions.....

Thanks In Advance.
