Oracle Error Message
ORA-26691: operation not supported at non-Oracle system
Reason for the Error
The apply process attempted an operation that is either not supported by the non-Oracle system or by the Oracle transparent gateway through which the apply is being done. Some kinds of DML (like procedure and function calls) and all DDL will cause this error to be raised.
Solution
Do not attempt to apply such LCRs to non-Oracle systems. If possible, filter out such LCRs before applying.
