In the Part Maintenance program, the checkbox “Use Part Rev” is selected by default, and when selected tells Epicor to use the “most current” revision when MRP runs REGARDLESS of the revision selected in Sales Order Entry (“most current” means the one with the most recent Effective Date).
LIMITATIONS:
This only works for the top-level assembly part number, and only for MRP-created make-to-order jobs . Out of the box, MRP will ALWAYS select the most recent revision of any manufactured subassembly. If you want to specify any other revision for a subassembly, this will require some sort of BPM(s) and Customization(s).
From the system help:
Use Part Rev
Select this check box if the Material Requirements Planning (MRP) should use the highest (most current) revision available of the part. If the check box is selected, an entry of the part number automatically specifies the most current revision.
If you clear this check box, you can manually create demand in MRP for different revisions of the same part, and the Epicor application honors the different revisions.
This option does not apply to requirements for stock. This check box has no effect if you do not use MRP.
