Comment 2 for bug 1966096

Working branch user/jeffdavis/lp1966096-delete-lineitem-perm-check has a fix:

https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/jeffdavis/lp1966096-delete-lineitem-perm-check

If the line item is attached to a purchase order, this branch will check if you have the CREATE_PURCHASE_ORDER perm at the PO's ordering agency; otherwise, if the line item is attached to a picklist, it will check if you have CREATE_PICKLIST at the picklist's org unit. Either way, acquisitions staff will be able to delete each other's line items, which is new behavior.

No pullrequest yet since the branch needs a bit of testing.
