    souces table:
    1001 3 300 20

    Target table:
    InvNo Type Measures
    1001 QTY 3
    1001 SALES 300
    1001 DISC 20

    I think we can use the sql statement with union of 3 sql statement like this format:

    select InvNo, 'QTY'AS TYPE,QTY from sourcestable
    select InvNo,'SALES' AS TYPE, SALES from sourcestable
    select InvNo,'DISC' AS TYPE, DISC from sourcestable

    But I think thgis is not the better solution since sql with union will be slower.
    May I know any tool in the data flow able to cater this situation?How to use the related tool?
    Thanks in advance.

    I just have a solution for this case.
    Unpivot tool at the data flow component will be very helpful for this case.
