Message text: Wrong type of conversion-relevant component &1
Type of component &v1& is different in CNV_INDX_STRUC(&v2&) than in
directory(&v3&) and this component is relevant for conversion.
This generally shouldn't happen, because it means that knowledge
gathered in CNV_INDX_STRUC doesn't comply with the real RELID
structure.
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
Update knowledge in CNV_INDX_STRUC table.
There is a program in development class CNV_21500, which compares RELID
structures in directory and in CNV_INDX_STRUC table. It might be
helpful to find out the actual structure of a RELID.
