Table error when using Unit of Measure Error

Summary:

Hello All,

Our client has a requirement to see Unit of Measure of each item inside demand planning tables.

As we dont have any standard measures to show UoM inside demand planning. I created a new attribute inside levels and attributes under product dimension and I created a new measure and used the attribute inside the measure expression.

Once I add the new measure post plan run in the pivote table it is through table error(I have added the measure in measure catalog). I have attached the screenshot.

Please let me know if anyone have faced this issue also, is there any other way to show UoM of the each items inside Demand planning tables.
