External bank imported successfully for a supplier but will not appear in Bank Detail section unless

 We need to update their bank accounts for large number of existing AP Suppliers; ( paid before by check and now need to make bank transfers ).

I used the external bank acct import document from note (Doc ID 948993.1);  (Documentation on Importing Internal and External Bank Account In R12: Bank API's And Q/A.)

populated the tables, then ran request : "Supplier Sites Open Interface Import";  and it worked successfully.

The problem now in application, when navigating to this supplier, i click on bank Details section, but the account is NOT there.  

I have to click ADD button, search for it and select so it appears for this supplier, then save.
