| release code (MM-PUR) |
A two-character identifier with which a person responsible for processing a document can release (approve) an item of a purchase requisition, a complete purchase requisition, or a complete external purchasing document, or cancel a release (that is, revoke an approval).
If a link to SAP Business Workflow has been defined for the release code, the person can refuse to effect release (withhold approval), thus rejecting the item or document.
