We are testing MiniMRP for purchasing/receiving duties, not for inventory. We will sometimes outsource welding and machining, and always outsource painting. How would you recommend handling sub-contracting?

Thanks

Not sure what you mean by 'duties'.

But lets say you have a product that includes a bunch of parts that you assemble and a sheet of metal that you send out to a sub contractor. The contractor cuts the sheet of metal, shapes it, welds it and returns it to you.

The metal, welding etc would be a sub assembly.

The top level assembly is, for example part number A001 and there's a few parts P001, P002 and P003 and your raw 'lump' of metal M001

The metal, once it's been welded and returned to you has a part number "WM001". You'd need to make this into an assembly as well so you 'BOM' for A001 would look like this.

P001
P002
P003
WM001
.. M001
.. WELDING


So, in the above example as well as a sheet of metal (M001) you have an inventory item with part number "WELDING". You see that the M001 and WELDING are offset to the right - that's just the way I write things to indicate that they are components of the WM001 sub assembly.

If you created an assembly like that and created a work order and built it you'd see the onhand inventory for P001, P002, P003, M001 and WELDING would all be reduced. That WELDING doesn't actually exist as a physical inventory item but if you look in the item detail you see 'Type'. Change that the MISC. Now when you build the finished product the cost of welding will be included but it won't be taken out of the inventory.

I could go on but have a play and see if what I've written makes sense

I want to add that I'm just a user like you. Not support. and the way I described is how we do it. In our case the sheet of metal is supplied to the sub contractor who stamps it out and folds and tacks it together to make a steel box and paints it and sends it back to us. I just have a part number for the raw sheet, a part number for the LABOR and another part number for the finished box.

Thanks for your reply.
We are looking to migrate from Part & Vendors that we have used to issue RFQ's and PO's. Since what we do is custom "one off's" we don't build assemblies, or manage inventory in the database. I want to avoid investing in any digital data beyond the drawings if possible. I was wondering if there is a recommended simple method to handle things like sub-contracts or outsourcing that did not involve creating assemblies in the inventory "item master".

MiniMRP can issue RFQ's and PO's

But how did p&v issue an RFQ or a PO if there was no inventory.

P & V has an "other" option when adding items to a RFQ/PO. you can make a PO using any number of "other" parts and enter unique descriptions for each line item.

This method allows you to keep track of "non-inventory" and "one off" items without adding them into your item master. It has been a useful work around for us.

You can also add a "non-stock item" to MiniMrp when creating a PO.

When you create a new Purchase Order (or RFQ) you bring up the list of items that can be added to the PO and the top two rows are "New Item" and "Non Stock Item"

If you add either of those to the order you can freely edit the part number and description.

A "New Item" will be added to the inventory when it's received. The "Non Stock Item" exists only in the purchase order so can be ordered and received but does not go into the inventory.

So I guess PV's "Other" is the same as MiniMRP's "Non Stock Item". Just terminology.
