Diagnosis
When you assign the EH&S value assignment type Total Solids to acharacteristic, the unit of the characteristic and the unit of the totalsolids have to belong to the same dimension.
(Environment parameter for the Total Solidsvalue assignment type: FRML_ESTCAT_TOTAL_SOLID)
Example:
Unit of characteristic = %, unit of total solids = % --> permitted,sinceboth units belong to the Proportion dimension.
Unit of characteristic = g, unit of total solids = % --> not permitted,since the units belong to different dimensions.

Procedure
Check the unit of the characteristic and adjust it if necessary.
