3120942 - Change Service UoM Leads to Error: 'Maintain conversions between UoMs ABC and XYZ'

Symptom

Services were created with incorrect unit of measurement (UoM) data. They were e.g. migrated with UoM "ABC" instead of "XYZ". When trying to change the UoMs, the following error occurs:

Error: 'Maintain conversions between UoMs ABC and XYZ' (where ABC and XYZ represent UoMs)

Environment

SAP Business ByDesign

Reproducing the Issue

  1. Go to Products work center
  2. Go to Service view
  3. Edit the related service
  4. Select View All
  5. Go to e.g. General tab
  6. Change UoM ABC to XYZ
  7. Error: Maintain conversions between UoMs ABC and XYZ

Cause

The service is already active. Generally, when you switch from one UoM to another, the system expects that you maintain the conversion between the two UoMs. This is the expected system behavior

Resolution

A suggestion would be to block this service and create a new one. A backend correction is not possible in this case.
