This might be a stupid question but does anyone know of a way to change the part UOM Conversion Factor on a part that already has a part transaction in the system? When the part originally got put in the system it was put in with the wrong conversion factor and now I am trying to fix this issue so t…

You are going to have to: Make a new part specific UOM for Class OTHER, and add it to Part’s UOM list. Set the Conversion OTHER.LB to inactive. Update the Reports that use the UOM. Preferably change them to use the Symbol.

What is the exact error message you get when trying to change the conversion factor?

@Jonathan where you specify the UOM Conversion Factor is grayed out so i can’t change it.

So you mean below fields are disabled? I enabled this by marking the Part Specific box on the UOM Class. I will check if there is any other validation to disable the ConvFactor besides this. [image] [image]

@Jonathan this is what it looks like for me. [image]

Found it, looks like these fields are disabled when PartUOM.HasBeenUsed is true. There is also a field UOMConv.HasBeenUsed but that is more general. You can update this to false at your own risk. As mentioned before the factor is pulled from the setup when a transaction needs it so there is a risk…

@Jonathan thanks but with how many different parts that are messed up @ckrusen way seems like it will work but there will be alot of code changing to get it to work. it does however seem like the best solution.

Before yopu dive into the really hard way, make sure there is zero QOH of the part before trying to change that Part Specific UOM conversion. A half-assed test I did showed that those are disabled when there QOH. And they re-enabled when the QOH went to zero.

AND ALSO if there are previous transactions at this level, and now you’re adding NEW transactions at a different level, your Finance department may come looking for you to share their government-supplied accommodations. Make sure you know the full extent of what you’re doing before messing with this…

I have tried closing all sales orders, closing all jobs and zeroing out QOH and it still will not let me change the UOM conversion factor for a part that needs to be changed. I have probably under 100 parts that need to be changed so I will give the options to my boss and let them make the decision …

FWIW - It appears that just using the part and UOM on a PO locks the Part’s UOM conversion factor. I did some testing on a part with a Part Specific UOM. After several different transaction types, I was still able to change the conversion factor. Created parttrans via Qty Adj, could still chang…
