Hi Rableen,
As from the error the SUM is trying to create and existing index.
EGT231 "'KEY_ZIC_C031U'," 4 EGT231 "'KEY_1009411'," 4 EGT231 "'KEY_1009412')" 2 ED0314 invalid index name: column list already indexed
he SQL statement was not executed 2EEDI006 Index " " could not be created completely in the database 2EEGT082 "Index" "/BIC/E100941-P" could not be created 2 EGT067 Request for "/BIC/E100941" could not be executed
So try to delete the index and re-run the phase. This may resolve the issue. Just check if its an primary index you may need to take precaution before deleting just get all required details of the index.
Regards,
Ram
