Co-Parts Setup and Job Quantity

We are trying to set up Co-parts for the first time (we are on Kinetic 2023.1). I haven’t been able to find any good documentation on the Method setup for Co-Parts so I am struggling to get a few things completed. Does anyone have any updated information for the Engineering Workbench? I don’t want to just set up a job, which is the only documentation I can find in Epicor’s help articles.

Issues I am having:
1). Is the material cost factor a % or a whole number split between the two parts?
2). I approved the Method and created a job with a Demand Link for 60 quantity, but both Part A and Part B are showing 60 each also. Shouldn’t it be showing 30 each?
3). When my operators claim parts on the MES, are they claiming 60 parts on the job total, or 30 of each part? I have seen some information about a Co-Parts tab that should be used to claim each part separately.
4). For scrap parts, can someone confirm that we would have to scrap and/or DMR from inventory (not off the job) so we don’t scrap both parts?

That is all the questions I can think of for now. If anyone has any documentation or work instructions they could share, or some time to walk me through this, I would really appreciate the help. Thank you!

If you have access to the (Classic) Education Course documents from Kinetic 2021.2 or previous, the Advanced Production Management course explains Co-parts in somewhat more detail (but the workshops are designed around the Classic UI). To answer your direct questions…

  1. Neither, really… but closer to a percentage. It’s entered as a ratio, so that if the Material Cost Factor for the main part is 1, and the factor for a co-part is 2, then the co-part will absorb 2/3 of the total material cost (2 times the amount of the main part). If there are multiple co-parts, the denominator of the ratio is the total of the values in the material cost factor column.

  2. No, the Production Quantity on a job is the number of items of the MAIN part part number that are being created. Within the MOM of the main part is how many co-parts are being created for each single unit of the main part. Effectively, you are creating a job for X number of main parts, and as a side benefit you are also getting Y number of co-parts. It’s just that with this functionality you can put quantity and value on those Y parts.

  3. On the Co-Parts tab, there is a grid with spaces for part created (completed, nonconform, scrap). This is a BIG change for the operators… and I haven’t personally used it in the Kinetic UI (yet).

  4. On that Co-Parts tab are spaces for nonconform and scrap, so each part can be handled individually. Again, I’ve not seen it in the Kinetic interface, but this is how the Classic UI works and Kinetic SHOULD have the same functionality.


You also need to make sure you have the rev set as sequentially or concurrently depending on how your co-parts are produced.

And if you run Mattec, it has to be Sequential no matter how you make your parts. :person_shrugging:

tell me this isn’t trueeee :sob:

We’ve found that this setting determines whether or not a family link is done. So, IF you have the family job capability where each copart jobs are linked (true for injection molders like us), it must be sequential. If you’re not using family jobs, you’ll be OK.

Okay cool, I probabyl misunderstood the family thing when they said it. I still don’t understand it. But we want concurrent jobs for co-parts and what I am understanding is that they do support it- based on your comment above.

Didn’t mean to scare you. As long as you’re not using the Family Parts modules, you’re good.

I have no clue what that is quite frankly.

That’s a feature in Advanced MES yeah? Not Epicor?

Yes. In AMES, a family job connects other jobs so that they are treated like one job. If you move the schedule, login, etc. it happens on all connected jobs.

Thanks, so more like batching.

For us, it’s often the left and right hand of the part.

us too

Originally, all methods were setup as concurrent. The thing that changes that is the Advanced MES. If you are not using Advanced MES, co-parts that run at the same time should be set up as concurrent.

@mroelandts Hi Michelle,

Sorry I missed your questions, but I was unavailable last week and didn’t get caught up until today.

  1. The material cost factor is a percentage. You need to set up Part A with a percent and Part B with a percent. Those percentages should add up to be 100%.

  2. If you want 30 of Part A and 30 of Part B, you need to make the job for 30. It will “automatically” set the copart demand of each part for 30 each.

  3. Your operators should be claiming 30 of each part. There is a co-part tab in MES where they record the total of each part.

  4. Right now, you can’t scrap parts individually (scrap is for a total of A and B parts scrapped). What we did as a workaround was to take the scrap parts to stock and scrap them from there. Same thing with nonconforming parts. I hear that 2024.1 will have a way to scrap or nonconform parts without having to do that (can do it at end activity).

Hope this helps make things a bit clearer for you!
