Documentation

Definition

The CheckValue or ChkVal function module in a Change module is used to check external data recorded or changed in the document for content correctness. Before this, the external data is transferred to the external data module via the ConvertFromText or ConvertFromTab function modules. After being returned from the CheckValue module, the possibly modified external data is transported back again. If the CheckValue module reports an error, then the GetErr module is called, via which one or more error texts can be transferred.
