Suppier Bank Account End Dated

Hi Oracle support,

When a Supplier Bank Account#  '001' is End dated in a particular Site  A , we get the message:

Warning = This bank account is attached to 9 documents payable. Would you like to replace the bank account in the documents payable with other available bank account as per priority?

at for ap_invoices_all. I see 9 rows updated Last_update_date

But only 4 out of those 9 Invoices belong to the Site A.  the thing is that the same Supplier Bank Account#  '001'  exists under Site B.

When I query at Invoices form, the system only did the Bank Account change at the 4 AP invoices of site A, which is fine. The 5 Invoices at site B  are not changing its Bank Account#,  but the record  history reflects  Last_update_date for   Today.
