Hi Experts,

We have a requirement that for 2 different groups of BUs, we need to direct the approval process into 2 different sets of approvers.

This is regarding changes made only supplier's bank accounts under Supplier Site level.

I.e. for BUs in Group_A, the approvers to be 1→2→3; and for BUs in Group_B, the approvers to be 4→5→6.

I thus configure the "Internal Supplier Profile Change Approvals" by distinguishing by Procurement BUs.

However, in a single Supplier, the bank account info is applied to all the BUs within both Group_A and Group_B; thus, when the bank information is changed, it somehow includes all the BUs configured in all the Supplier Sites into 1 single Profile Change Request, and causing a chaos: not only both Group_A's approvers and Group_B's approvers are both included, but also, they are repeated.
