Message number: 210
Message text: Irrelevant "Priority" flag set for one of the fields of table &1.
"Prioritiy" flag was set for one of fields of table &V1&, however the
the duplicate processing type is '&V2&' and setting the "Priority" flag
doesn't make sense.
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
"Priority" flag should only be set if the CNVTABLES-SUMUP value for a
table is 'A'.
Check whether you want to use duplicate priority handling scenario and
depending on the result
delete the unnecessary "Priority" flag or
change the CNVTABLES-SUMUP value for table &V1& to 'A'.
