This depends on how your MRP/ERP system has been implemented and the
philosophy of your Configuration Manager. As long as the supply chain
knows where to find the correct parts list for the assembly they are
assembling it does not matter.

Subject: [DC] Assembly Documentation Question

The company I work for is going thru some documentation change
discussions.
Below are the documents that are revisable. (The parts list contains all
the IC's, cap, res. etc. and documents.)
The feedback I'm getting is the the parts list and the assembly drawing
should ALWAYS be the same revision (becasue thats the way its always
been).
Everywhere I've every worked, these are independent documents.

Here are my scenerio case: (All documentation released at Rev. A)

Scenerio (Rev: B): A  part number change, of a 1K, 5%  resistor to a 1K,
1% resistor.
In this case, the part list and schematic would change, but it has no
effect on the assembly (because no part number or value is on the
assembly
drawing).

PL1234567-1             Rev:    B       Parts List
        AW1234567       Rev:    A       Assy Dwg
        DS1234567       Rev:    A       Drill Dwg
        PC1234567       Rev:    A       Artwork
        PA1234567       Rev:    B       Schematic

Scenerio (Rev: C): The length of the screw holding the stiffener bar is
changed from 3/8 in. to 1/2 in.
The change is to the parts list only, the assembly drawing stays the
same.
(no 3D view or side view)

PL1234567-1             Rev:    C       Parts List
        AW1234567       Rev:    A       Assy Dwg
        DS1234567       Rev:    A       Drill Dwg
        PC1234567       Rev:    A       Artwork
        PA1234567       Rev:    B       Schematic


The current discussion and question is;
-Can the parts list be independently revisible, from the assembly
drawing?
-What do most of the assembly houses usually like?


Thanks for any response to this question.
