Issue while Making UOM Mandatory on AR Invoice Page

Summary:

Hi Team,

We have a Requirement to Make UOM Mandatory on AR invoice Page.

While doing the same through Sandbox the validation is checking all the lines and asking to fill-up UOM for All Lines.

When user Creates New Transaction By default System shows 10 Lines and user will enter data in 1-2 Lines and Remaining Lines are not required.

System shows Error Message stating UOM is Required and now allowing user to complete the transaction.

So User have to Manually Delete Addition 8 Lines Before Completing invoice.

So we want to Check is there any way we can configure Sandbox to Make UOM Mandatory Based on Description Value ?
