Edit a purchase bill

Goal

Correct a purchase bill while it is still editable.

Purchaser / AP clerk (purchasing.manage).

Draft bills are editable.
Posted bills are normally immutable. Day-to-day corrections use a debit note, not silent edits. Elevated document-edit policy (super-admin snapshot) may allow limited posted edits without re-posting GL/stock.

Open the bill from Purchase bills.
If status is draft, choose Edit, fix header/lines (supplier, costs, tax, warehouse), and save.
If status is posted, do not expect free edits — create a debit note from the bill or debit-notes list.

Draft changes are saved, or you are on the correct correction path for posted bills.
