Message type: E = Error
Message class:  CNV_20110 - Pre-analysis for chart of accounts conversion 
Message number: 026
Message text: Value &1 in set class 0000 is relevant for conversion
In table SETLEAF, value &V1& (which corresponds to a G/L account or
cost element) was found for set class 0000, set name &V2&.
With regard to the fact that entries for set class 0000 are cross-chart
of accounts, you should check if this value is relevant for the
conversion. If necessary, add it to the mapping in phase "Maintain
mapping tables", step "Maintaing duplicate cost element groups / profit
center account groups / intervals / sets".
Note: This is necessary only if the value &V1& is really relevant for
the conversion.
