Release Prerequisites
Definition
The release prerequisites indicate the sequence in which a purchase requisition or an external purchasing document must be approved via the release codes. The release prerequisites are defined in the Purchasing Customizing facility (in the release strategy).
The approval procedure for purchase requisitions in an enterprise may be set up in such a way that a department manager must approve a requisition item before the next level of authority (e.g. the cost center manager). In this case, approval by the department manager is a prerequisite for approval by the cost center manager.
