Reverse a Purchase order Line Type J

Hello,

We have a Purchase Order Flow like this:

Requisition (OU) --> PO Request (OR) --> Purchase Order (OB) --> Invoice(OF)

* OU is a Self Service Purchase Order

* OR is a Typical Purchase order but without Approval process.

* OB is a Typical Purchase order but with Approval process.

* OF is a Purchase Order created from "Order Release P43060" from previous OB. There is an approval route setup here to approve services invoices.

Our problem is that if there is a mistake with partial Order Release, we don't know if we can reverse this Partial Order Release from OF to Ob.
