Residue Monitoring: When you enter data for an active substance, an error message is returned, stating that it is not possible to enter the maximum residue level, to select a regulation and/or the ARfD value for an active substance. However, a statutory maximum residue level exists. What is the reason for this?

Check whether the residue definition of the active ingredient is a sum definition. In the QS database, the entry of maximum residue levels and the selection of the regulation for active substances with a sum definition is only possible for the sum value. These entries cannot be made for the individual active substances of the sum definition and result in an error message.
