Default Vendor becomes unselected when adding UOM

This appears to be a bug unless someone can help explain what is happening (and possibly how to avoid)

 

I am attempting to add a 2nd UOM for a group of items purchased from our default vendor. Typically we might buy an item in a 100 unit case but the default vendor offers the same item in a 200 unit case as well. 

 

When I add the new UOM on the Vendors tab of the Stock Item and click save, the new UOM will be listed with the original one and only the old UOM will have the Default (for Vendor IsDefault) checkbox checked. However, if you refresh the page you will discover that neither row has the default checkbox selected!

The item no longer has a default vendor?! How? and why? 

 

If you try to add the new UOM from Vendor Inventory (PO201000), you get an error “An attempt was made to add a duplicate entry.” even though that page is capable of displaying and editing multiple entries

 

Is there an easier way to load this data without removing default vendors from our items?

​@kyle90 TThis behavior appears to be unusual. It may be worth creating a support case with Acumatica. Based on my understanding, this could be occurring because the same vendor is being used multiple times with different UOMs. Please check with Acumatica support to confirm whether this is the expected native behavior or an issue that needs to be addressed.

    Hi ​@kyle90 ,

    Please review the following steps, which may help address the issue.

    1. Ensure that the Multiple Units of Measure feature is enabled in Acumatica.
    2. Navigate to the Stock Items (IN202500) form.
    3. In the Units of Measure section, specify the additional UOM you wish to add.
    4. Define conversion rules between the current and new UOM to ensure accurate quantity calculations.
    5. This process allows you to add a second UOM without removing default vendors.

     

    Hope this helps.

    Thank You,
