Recommendation on 1 purchased part that breaks into 2 parts used to manufacture product

We have a situation where we will be purchasing 1 part and that one part will break into 2 different parts that are used to manufacture a product. What are best practices for setting this up in Epicor?

• Make 3 parts. The purchased part and two manufactured parts.
• Make a BOM for one of the two mfgâ€™d parts. With the other mfgâ€™d part a co-part.

Does anyone know if you could make a BOM for other the Mfgâ€™d part (the one that is the co-part on the first BOM), with that first Mfgâ€™d part being the co-part on the second.

Ex:

• Part PUR-001 - Purchased part to be split into parts MFG-001(qty 1) and MFG-002(qty 4)
• Part MFG-001 - Mfgâ€™d part from PUR-001
• BOM consists of (1) PUR-001, and also makes (4) of co-part MFG-002
• Part MFG-002 - Mfgâ€™d part from PUR-001
• BOM consists of (0.25) PUR-001, and also makes (0.25) of co-part MFG-001
• With mfg qty to be multiple of 4, so 4 of PUR-001 makes 4 MFG-002 and 1 MFG-001

Does MRP create jobs to meet demand for co-parts? Like if part MFG-002 didnâ€™t have a BOM, would it make a job for MFG-001, knowing it would get MFG-002 out of it?

And if MFG-002 did have the BOM (with MFG-001 as a co-part), would MRP just make a job for MFG-002?

Havenâ€™t tested, but I would imagine that if there is any demand for either MFG-002 or MFG-001, youâ€™re going to be told to buy PUR-001, and run as many of those as you need to get the correct number of end items.

Hope that they are used in proportional quantities!

Thanks so much! If Iâ€™m following with the copart idea, we can achieve the two following steps.

1.) PUR-001 are received and stocked in inventory
2.) A job for sellablePN-001 would
-Pull 1 @ PUR-001 from inventory
-Create 1 @ MFG-001 and 1 @ MFG-002
-Could it also consume 1 @ MFG-001 and 1 @ MFG-002

Iâ€™m not sure if 1 job could create and consume an MFG-001 and a MFG-002.

Definitely pay close attention to your costs when you test. We have lot of issues with co-parts and costs, but we take 1 part and make numerous co-parts.

Do we have to buy a module to use CoParts?

Where I used to work, we had a â€śBoxâ€ť that we sold. (lets call that â€śBox1â€ť)â€¦ We found that we could purchase the box, but it had a â€śTerminal Blockâ€ť attached to it (lets call this TB1). Box1 didnâ€™t need the terminal block, BUT, we needed TB1 for another product. Sooâ€¦ we created three parts:

1. BOX1 - the sellable part (this had additional manufacturing on it as well)
2. TB1 - the terminal block
3. BOX2 - the PURCHASED PART that included the terminal block.

we would sell BOX1â€¦ this would create a JOB for BOX1. the BOM for BOX1 called out a BOX2 on the BOM. the Material Detail tab in engineering workbench we entered the SALVAGE part number of TB1. The result was a purchase order demand for BOX2â€¦ a job for BOX1, and when we finished the operation to cut off TB1, we â€śSalvagedâ€ť the part from the job. This is easier than coparts, becauseâ€¦ wellâ€¦ it just is.
