There needs to be a way to delete a manually packaged PO without also deleting all the POLs associated with that PO. I can understand not allowing this if the PO is closed, but if the PO is only in "sent," then it should be allowable to either delete that PO without also deleting all the associated POLs OR allow editing that PO to attach additional POLs to that PO. This would essentially be the same logic when manually creating an invoice in Alma: it's possible to add as many POLs as needed when creating an invoice in Alma by editing the invoice and adding POLs. It should be the same when manually creating POs. This would benefit users by not forcing them to recreate POLs for every purchase within the same manually packaged PO if a mistake had been made with the PO and it needs deleted. The amount of work to do this is quite high.
