ePro Change requests and errors

Hello,

We are on PS 9.2 PUM 39 and Toolset 8.58.11. We are currently using ePro Classic.

We allow our users to create Change requests through the Manage Requisitions page for certain instances. We're seeing something with pricing changes for Amount Only requests or, more specifically, instances where the requestor neglects to check the Amount Only flag on the Req line and the Buyer flags the line as such once the PO is created. 

What we're seeing is that, when the requestor attempts to add money to the line later in the year, the line routes for approvals as expected but the change generates a processing error because the PO line is not the same as the Req line.
