Hi @Chalut, Mylène - ITSLM/GCSTI ,
Please make sure that the Error Output has data in your package.
If you are using isnull
expression to check the null value, it will not return error data from my test.
Why not load the flat file data into a staging table and then use TSQL command to select the valid columns and invalid columns, and then load them to the destination.
