Hi Nikolaos,
Probably I did not explained myself so well. How Can I link them in a way the each row will be releated to the row of the prodId.
More specifically I have this example:
I change a little bit the logic. Instead of getting all the OprId fixed, I will group maximun 10 operation Numbers (10 groups), so group column 1 will be OprNum 10, Column2 = OprNum 20, 30...till OprNum 100.
How do I make the Query in order to link each ProdRoute Datasource with the main ProdTable Datasource?

I think Is the first time I try to do something like this in dynamics
I am using a FormListPage by the way.
I really appreciate you help.
thanks a lot!
later I can think of grouping the column by color as you suggested, I don't know if its possible.
