Did you manage to solve the sorting issue, if you for example click on “Customer Group” the “same item” will not stay together as each row is sorted independently.
We have some items which are located in multiple warehouses and had the idea to show only Warehouse and Quantity fields so it’s easy to see it’s the same item…but sorting does not work then.
Actually i didn’t realize ,this issue until you pointed it out , Thanks,
Well for that we are just added a filter on top , and search for each group on that.
You can always do order by group in query if you want it by default.
Still no solution for Sr no though , seems its in the report interface class in the framework itself.
