Error: Unique Constraint Violated: Table (xxxx)

Dear all,

firstly this is the error I get when activating a .hdbtim,

ERROR      playpen/db/ZGS.hdbtim

           Repository: Internal error during statement execution, please see the database error traces for additional details An error occurred when inserting data from csvfile to table. CSV-file: playpen.db:ZGS. Target Table: playpen.db::ZGS Exception:: unique constraint violated: Table(playpen.db::ZGS) at ptime/query/plan_executor/trex_wrapper/trex_wrapper_body/trex_update.cc:1391

The error is caused after I joined my ZGS table to the M_TIME_DIMENSION table in my Att View. Before the join, when there was no join in the Att View, everything worked fine.

I have deleted the records in the M_TIME_DIMENSION, and I only have 1 record in my ZGS.csv file, but still no good.

thanks in advanced
