Hi there, I'm starting with stream [col A, col B]. Based on filter on [col A], I merge I merge some rows [col A=x] with other set [col C] and calculate left over [col A!=x] in another [col fxA]. Then I want to UNION these streams again which I can't because one stream has [col A, B, C] and the other has [col A, fxA]. I don't mind null values - all I want not to manually adjust the order and names of the columns. I could do this in Excel PowerQuery. Is there a way of doing it in Pentaho?
