hi all,  newbee question here but i can't seem to find an answer.   I am trying to create a timechart table grouped table that has product as the parent and error codes as the child.     I can't seem to get any sort of multiple column grouping where i can have separate calculations for each column variant.   so the structure would losely be:                                      Product1                                                                                                                                Product2                200         201       300       ......and so on                           200         201       300       303         ......and so on date1      34             23      22                                                                 43           23         76         23 date2        2             43        45   .....and so on.   it would be fine to coalesce the prod and error code , but i can figure that out either i.e. 200Prod1    201Prod1     200Prod2    201Prod2   Is this something that is logically doable? ...
