Which Approval attribute should be used to check if any or all lines are cancelled in a PO

Summary: Business requirement: When any or all lines in a PO are canceled as part of a Change order, it should go for approval for Purchasing admin group.

Content (required): We used the attribute Entity Change Type = Canceled, to check if any/all lines in a PO are canceled.

But the attribute is failing to generate approval hierarchy when in the same PO, one line is canceled and a new line is added.

Is there any other attribute we can use to achieve this use case?

We need the PO Change order to go for approval if any/all line is canceled. If in a PO, a new line is added, or an existing line is modified, and along with that, at least one line in a PO is canceled in the same change order, the approval should go to Purchasing admin group.
