When user create a PO, using procurement categories (no physical or financial inventory maintained). Processed the PO by posting confirmation and receipted and PO is due for invoicing.

At this stage user updated unit price of the PO line through request for change process which has been approved, and PO was confirmed again.

Making changes after product receipt causing inconsistencies in accounting distributions and reconciliation differences in accrual account between receipt and invoicing.

Technically FinOps should stop user updating the unit price or net amount once receipt is posted. This looks like a limitation in the product and needs to be addressed. We were able to replicate the issue while 3-way matching is in place. 

Hopefully this will get reviewed and addressed as a defect soon.
