I'm doing operation on a dataset containing data from a sql table named Test_1 and then get the updated records using the DataSet.GetChanges(DataRowState.Modified) function. Then i try to save the dataset containing the updated records on a different table than the source one (the table is names Test and has the same structure as Test_1) using the following statement: sqlDataAdapter.Update(changesDataSet,"Test");

I'm getting the following error : Update unable to find TableMapping['Test'] or DataTable 'Test'

I'm new to ado.net and don't even know if it"s something possible. Any advice is welcome.

Just to provide a bit of context. ETL jobs are importing data in temp table with same structure as the original but with _jobid suffix. Right after a rule engine is doing validation before updating the original table.
