# PO Suggestion Quantity and Supplier UOM Conversion

I have a purchased part that has a min order quantity. When I try and add an entry for this part to Supplier Price List and specify a supplier UOM, something unexpected is happening with the PO suggestions that are generated.

It is rounding down the min order quantity from 8000 to 7999.999999, and then since that PO is not sufficient to bring us above minimum, it writes another, for 7999.999999.

Why is it not just writing the PO in the min Order Qty in my UOM?

What is your default for POs at the Company level?

On the Supplier Price List?

I tried unchecking Default UOM thinking that might help and got the same result.

It definitely seems like it is starting out with the correct OUR Quantity, figuring out the supplier quantity, but then for some reason it is going back from the supplier quantity and re-writing our quantity, or something like that. Frustrating.

That is weird. I would think that Default UOM would work.

Do you have any price breaks? What is the UOM there?

Or see what happens when you create a new Price List for a Supplier and you change the Supplier UOM?

No price breaks.

I really appreciate the help, but Iâ€™m not quite sure what this means.

It seems like if I use a supplier UOM that has a round conversion factor, it shakes out ok.

A conversion with a decimal, it does the thing I donâ€™t want it to.

My conversion factor here is 1 LM = 16.5 SQFT

Start out at 16000 / 16.5 you get 969.6969696969697.

Ok cool, write the PO for that.

But it doesnâ€™t stop there, it rounds the supplier quantity (fine) and then does the math back the other way to change our quantity.

If you set the lot multiple in part > site > planning does it change the Supplier quantity? I know it changes suggestions for us.

What is the PUM on the Part?

@hackaphreaka and I are in this problem together so Iâ€™ll answer both questions.

@gpayne, I just updated the lot multiple to 8,000 SQFT and no change.

@jkane, the purchasing UOM was SQFT, like the inventory UOM. I was using the override checkbox in supplier price list to inform the PUM, but I just ran MRP again with the PUM set to LM and no improvement. Denied!

Itâ€™s as @hackaphreaka said, it looks like itâ€™s doing the conversion to get the supplier quantity and then turning around using that number to calculate a new â€śour quantityâ€ť. It only doesnâ€™t work because the two donâ€™t convert cleanly without a remainder. You change the number by performing the calculation.

I just submitted a ticket with Epicor to see if they can shed some specific knowledge on whatâ€™s happening in the background and whether or not this is intended behavior.

I was going to say that next. Iâ€™ve come across this before, just canâ€™t remember the outcome.

I just saw a this KB that suggests unchecking allow decimals, but I donâ€™t know if .5 should be allowed.

https://epiccare.epicor.com/epiccare?id=epiccare_kb_article&table=kb_knowledge&sys_id=b28d70ecdb2d14547a572a9b8a96198a&searchTerm=po%20suggestion%20regeneration%20lot%20mult%20uom

Yeah, we were discussing the possibility of removing decimals from the SQFT UOM.

However, it seemed like an overcorrection to do so, especially before we knew if there was some other problem happening.

If we do decide to turn off decimals on that UOM (or if Epicor replies), Iâ€™ll post back here with the results!

They should reword this KB to say concession rather than resolution. I wonder what we are supposed to do if turning off decimals is not really an option for us.

If you could not turn off decimals you would be forced to alter the quantity on the suggestion which can be done in POSugg.GetRowsPlant as the workbench loads them.

I guess not understanding why these are my only options are what Iâ€™m having a hard time with.

Is it because I am creating an impossible situation? I want to write a PO for exactly 8000 sqft, but the moment I want to include a supplier quantity on my PO alongside that, if the math doesnâ€™t work out, I have to write the PO in some other quantity, not exactly what I want?

There are possibly other options, I am just quick to put in a fix and move on and not willing to explore other ways to deal with it.
