Message text: For org.unit &, org.unit2 &, new value & there is more than one prio flag
The priority indicator specifies the original value whose field
contents are to be used as target values during a merge of data
records. This is why this indicator must be set for exactly one of the
original values if two or more records are to be merged into a single
one. For the given merge, however, the priority indicator is set for
more than one of the original values.
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
Check the entries for this merge in table CNVRENAME and make sure that
the priority indicator is set exactly once.
