What causes this issue?

The Quantity Conversion Interface (QCI) calculates a set of target
quantities based on a source quantity and source UoM and a set of
quantity conversion parameters (density, heating value, reference
pressures and temperatures) for a given list of target units of
measure. Before the calculation can take place, the set of target UoM is
checked. This check failed, since at least one of the target UoM in the
internal table is not defined .

System Response
