Purchasing Unit of measure for alternative vendor on an item

Hi Miro1,

I appreciate the steps you've made to resolve the error.

You may have incorrectly set the unit of measure for the product. You can verify this by going to the Items & Inventory page.

Let me walk you through the steps:

1. From the Edit menu, then select Preferences.
2. Select Items & Inventory.
3. Go to the Company Preferences tab.
4. Check the Unit of Measure section.

Also, can you share with me the exact error message you get when atttempting to add an alternative vendor for an item? So, I can provide the correct solution based on the error.

Feel free to check this article that has information about measure of unit: Use single and multiple units of measure for items.

You can always visit us here again if you have other questions. We'll be happy to help anytime.

Thanks for the reply.

Set up as "Multiple U/M per Item"

The error that comes up is simply "Go to the field in red font and fix the error" - with the Purchase U/M being the only text in Red.

I'm not the administrator so I'll forward this information but also "accept as a resolution".

Thanks, I hope it will work

Hello Miro, 

Please let us know! And if you have any issues, we will be here ready to help! Take care for now! 

Still not working correctly

The administrator followed the previous instructions and the issue persists.

I can add the vendor as alternative to an item in item edit however no further actions can be taken.

If I go to the Vendor Center then Manage Vendor Items, any edit to the item (adding cost, vendor part) errors out while saving with the message "Enter a valid value in the Purchase U/M".

No value will work in the Purchase U/M; the original PU, the wanted PU, or leaving blank.

Conversely, I cannot go directly to the Vendor Center/Manage Vendor Items to add an item as an alternate at all. Errors upon saving with the same message "Enter a valid value in the Purchase U/M".

Hi Miro1,

I appreciate your update about your situation with your units of measure. I would recommend having a screen-sharing session with our QB Desktop Support so they can pinpoint the cause of the error. I wish I could, but such an option is not available in the Community yet.

1. Click on Help.
2. Choose QuickBooks Desktop Help.
3. Choose Contact us.
   
4. In the description field, enter a summary of the scenario and hit Continue.
5. Click Message an agent.

I also want to add this article as a reference Use single and multiple units of measure for items.

If you have any other concerns, please don't hesitate to go back to this thread.

You could enter a different related unit for the second supplier meaning the exact same? Like for sup 1, box, for sup 2 carton...

Thanks for joining this thread, jaapkrijger.

Yes, you can enter different related units for a second supplier that are the exact same as your previous supplier's related units. Units are defined by the number of base they contain. For example, if your base unit is an inch, a related unit might be a foot, which is defined as containing 12 inches. Another related unit could be a yard, which is defined with 36 inches.

Related units make it possible to show quantities of the same item in different measurements. They allow you to purchase items, count them in measurements, then sell them by measurement.

I've also included a detailed resource about working with related units which may come in handy moving forward: Use single & multiple units of measure for items

If there's any additional questions, I'm just a post away. Have a great day!
