Message type: E = Error
Message class:  CNV_20100 - Messageclass for chart of account conversion 
Message number: 104
Message text: Report &1 (&2): Global variable &3 is not defined or has '*' as value
Table CESETS and CEFORMF contain report painter data. Report painter
definitions can (among others) contain G/L account numbers (RACCT) or
cost elements (KSTAR).
The system found that for FIELD = &V2& the global variable &V3& from
report (APPLCLASS,SUBCLASS,TABNAME,FORM) = &V1& is not defined or has
the value '*'.
As a result, the report &V1& may not be converted correctly.
Reports should always be checked for logical consistency after the
conversion. This is particularly important if complex selection
characteristics are used.
After the conversion, check report &V1& manually for semantic
correctness.
Go to transaction GRR3. Choose the library, to which the report belongs
to.
The library is indicated in the third value: &V1&
The report name is indicated in the fourth value: &V1&
Check the correctness of the indicated G/L accounts / cost elements
manually
&ADDITIONAL_HINTS&
If you want to convert tables CEFORMF and CESETS independent of org.
units, call the transaction CNV_PARAMS and set the parameter
CNV_20100_CEFORMF_ORGINDEP to X.
