Multiple LE Invoice Lines in Single Invoice with multiple Trade Operations (Different BU)

There is a scenario where Single Invoice has multiple lines referring to different Legal Entities, but at invoice header level only one LE is entered.

As part of LCM process, these invoice lines needs to be updated with Charge Reference detail under Landed Cost tab in Invoice and requires to be associated with Trade Operation.

When we try to associate Invoice lines to TO charge lines, it gets associated with the only TO charge line where TO BU is same as Invoice header BU. But, invoice lines are facing NO MATCH where charge reference TO BU is different from Invoice header BU.
