How to handle drawing revisions after a BOM is issued

Revisions after issue are normal in facade work. The failure is a second Excel BOM that never quite replaces the first. Spectr keeps a project-bound product record so a drawing change updates the same twin — instead of creating a parallel universe of part numbers.

Key facts

Generic ERPs often want a formal ECO circus for a mark that moved two inches.
The shop will fabricate the paper on the wall if the system is a week behind.
Already-cut material needs a decision: rework, scrap, or use on another mark.
Field and shop must see the same revision, or you will hang last week’s panel.

How shops handle this

Freeze who can issue
One issued set. Not three PDFs in three chats.
Update the product record
Change the twin. Do not clone a thousand SKUs.
Tell the floor what is already cut
Inventory and WIP have to be visible or the revision is fiction.
Tell the field what not to hang
A crate can be right for an old revision. Labels should make that obvious.

Common questions

Should we wait to issue until drawings are “final”?

They are never final. Issue in phases that match the elevation you are allowed to build.

How do we prove what we built?

The issued revision on the product record is the story you will need months later.
