Is The CAGE Code (DAI) column really still required on modern engineering assembly drawing parts lists?
Commercial world and/or Military, most of the books and standards I have say it is a mandatory column in a parts list. My people are talking about eliminating it as we now mostly commercial applications, we really still do some military jobs too. If they want to go to two different systems so be it, I am not recommending it, but it is not my choice. I just want to know if you guys have any insight on this?

It's mandatory on everything here, but I don't know who mandates it.

Do you actually fill in Cage Codes or use a general note like: "see note 1" and say a note in the general note that says: "1. vendor item-see source or vendor item control drawing"?
Thank you,
Frank
Merry Christmas to you all, you guys have helped me out many times!

It depends on the customer's documentation requirements. Sometimes it's sufficient to just enter the manufacturer's CAGE code and part number on the B/M.

In an assembly there could be two different parts with the same base part number, but different makers. The CAGE is the only way to distinguish them.
Perhaps they are thinking that since the procurement system already records this and since the drawings aren't deliverable, as they might be under a military contract, that they are covered. True, but it leaves them open to synchronization errors where there is no way to discover when there is a lack of synch. The joke, a man with one watch knows the time; a man with two watches is never sure? The inverse of that is that a man with one watch doesn't know anything about how well his watch performs; a man with two watches can compare them and see what causes one to slow or run faster than the other and is better equipped to spot problems.
The alternative to using a CAGE on the PL is to assign in-house numbers to purchased parts and make drawings of those purchased parts that call out the maker name and address. In fact, most defense contracts prefer this because that independent drawing can have all the information that is critical to using the part, allowing inspection to verify that, over time, the part maker doesn't alter the construction of the part. And yes, suppliers change the functionality of parts with no change to the base number all too often.
In addition, the separate drawing allows for the case where the original part goes out of production and an alternate is required. Without knowing the important characteristics of the part, it is an expensive operation to retrieve that info for the purposes of either designing an in-house replacement or locating a new supplier.

Guys,
I was under a little different impression, I thought I read last night the CAGE Code was NOT needed to be entered in the parts list it was the same as on your drawing CAGE (basically your parts). It also does not need to be in if it is defined by a nationally recognized standard part.
I thought it was to be added if the item specified was a Source or Vendor Item Control Drawing that was controlled by an outside design activity, therefore, NOT your own CAGE Code.
Historically, we have all the Mil spec parts and all purchased parts on Control Drawings under our own part numbers. I was trying to advocate moving away from that. From 3DDave’s comments I am getting the impression that there are good reasons to do just that.
Basically, if you are saying you are following ASME Y14 or MIL-STD-100 are you actually in non-conformance at audit time, if you do not follow this particular practice?

It is typically assumed that the CAGE on the drawing is indicative of the default CAGE for all parts that either don't have one or have a related specification. OTOH I had one whiny Doc control person complain that dash numbers in a weldment drawing PL were insufficient to describe the parts and the parts all needed the drawing number prefix, mostly because they were too stupid to figure out what to enter into the ERP system.
I'm not sure what you mean by "there are good reasons to do just that." I'm hoping it is keeping the control drawings. I've seen the ugly results from those occasions when people try to cut the drawing count by just using the vendor number, only to have the supplier change some critical item or stop selling the part.
