The introduction of an active check using so-called "Smart" filters makes it possible to monitor the selected interval between the DATE_FROM and DATE_TO items during the entry of filtering conditions: If the interval is too lengthy (according to application parameterization), you are made aware of this fact when the filter is applied through the color-distinguishing of the item and a message. A filter with an unauthorized interval cannot be applied. The Smart filter appears on the filter of Invoices Issued.

A passive check is carried out to detect whether the overview made it to its work station upon its last launch by the user or whether the last filter used was successfully applied. If not, the system automatically displays the problematic filter upon the next access to the overview and notifies the user that the filtering conditions need to be changed. Passive checks are implemented on all overview functionalities with the filter.
