Dear Team

I am setting up the AME for AP transactions for two Operating units. The requirement is as below

I created two different rules for each OU. The setup is as below

TRANSACTION_ORG_ID = UK

For GERMANY

SUPPLIER_INVOICE_TYPE_LOOKUP_CODE in (STANDARD)

SUPPLIER_INVOICE_TYPE_LOOKUP_CODE in (CREDIT)

TRANSACTION_ORG_ID = GER

The Approval Group is same for both OU

The problem I am facing is -
