1.   I was wondering what the 'NAME' drop down menu in the Transformation tab of the Transform Data task is suppoed to do? I mean whats the differnce between <none selected> and DTS_Transformation_1?

2. Again under the Transform Data when one goes under Destination tab, whats the differnce between Populate from Source,which will set the type of the column to not quotable and the Execute, which will set the column to quotable?

    1. the 'NAME' dropdown is where you can select which of the transformations you want to edit. Each column-to-column mapping in the list below is a seperate transformation, and you can choose to edit one of these. If you click on the transformation itself, it will automatically select the correct value in the dropdown. It has no meaning when you save the task, it is simply a method of selecting a particular transformation before you click on the Edit or Delete button.
    2. When you set up a Transform Data task with a text file as the destination, you need to specify the format of the output file.
    WHen you click on the "Populate From Source" button the DTS designer checks the source table you are using and proposes a file format based on this. It populates these into a grid with each column that exists in the source table. For numeric fields it proposes that you create these as non-quoted fields, while it propses that all text type fields are quoted. You can then edit this proposed output by clicking any of the fields to remove (ignore) them, by changking the quoted/unquoted option
    Once you click on "Execute" you have accepted whatever was in the dialgo box, and htis is what will then be used as the output.
