Message type: E = Error
Message class:  CNV_10020 - Message class for package 10020 
Message number: 191
Message text: Conv. path &1: Total of fragm. lngths &2 differs from lngth of TDetObj &3
The length of the target determination object of converter path &V1& is
&V3&. The total length of the fragments defined by the conversion rules
is &V2&, which means that it is different from the length of the target
determation object. This is not possible.
Define the conversion rules so that the following condition is
fulfilled:
Total length of the conversion rules = length of the target
determination object
