    Have you tried to Preview your Table Input step?

    Is this only a two-step transformation (1x Table Input and 1x Group By)?

    I suspect not. What are details of rest of transformation? Without extra detail, probably hard to get help.

    When you say you've used 'Preview'... are you using Spoon's 'Preview' function on each step, or do you mean you used the 'Preview Rows' function in the Table Input step?
