Be careful, don't confuse between the key column into a schema and Expression key column into tMap.

Check the Key column from a schema will not improve performance into tMap, yet set an Expression key into one of your lookup will do.

Ok I define a key on my second TMap. I will send the results after.

Thx.

Have you tried to load a temporary table as output in the first job ?
Then you could map it with the output table in the 2nd job.

Hi,
Make sure that the metadata schema in yout tMap and in your tAccessOutput match exactly (including datatype) with the schema in your final database
