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?
