Prevent the Cancel of a PO if an un approved invoice exists

Update the IDEA name to align with the Case file how IBM would solve this problem.

We have a PO that has been canceled that has an invoice that is approved. We need to reverse the invoice as it was invoiced in error.

When we try and approve the REVINVOICE we get the following error message

BMXAA2013E - Could not change invoice 99133 status to APPR.
BMXAA3268E - The status of the purchase order should be Approved or In Progress.

PO 41918 rev 1 is in CAN Status
PO 41918 rev 0 is in REVISD status

Invoice 62761 is in APPR status (Type Invoice)
Invoice 99133 is in PENDREV status (Type REVINVOICE)

This has been confirmed to be a scenario that is not accounted for and I have been asked to create an IDEA for this.
