I have a table
as below
Art PP No ArtDate ArtQty OPDate OPQTY
102844 1100023223 02-09-2015 0 31-08-2015 0
102844 1100023766 03-11-2015 0 05-11-2015 1
102844 1100023766 03-11-2015 1 05-11-2015 149
102844 1100023766 03-11-2015 149 05-11-2015 1
I need to group by
and expected answer
Art PP No ArtDate ArtQty OPDate OPQTY
102844 1100023223 02-09-2015 0 31-08-2015 0
102844 1100023766 03-11-2015 150 05-11-2015 151
How to achieve this?
