Symptoms

When there's picking work with multiple license plates in one location, the quantity is not valid for the ea unit and you receive the following error message:

The quantity is not valid for unit 1%.

Resolution

Verify that the Unit sequence group ID and Unit conversions fields on the released product or product variant are set correctly.
