I've got a report which shows sales per product(rows) for multiple stores(columns).
I've ran the report for 3 products and all stores, and only one of the products has sales for all 8 stores, the other 2 products have sales for just 7/8 stores. But where the sales cells should be empty for those other 2 products and the 8th store, the sales values from the one product which sold at the 8th store are repeated for the other 2 products. It's like because the cell didn't get a new value for the new product, it's just repeating the last value it had.
When I execute the query in SSMS with the same parameters, the results shown are correct, with no repeating values and nulls where expected, so I'm assuming the issue is in the report.
I can't understand how the sales values can appear for another product when the rows are grouped by the product code
There are no expressions relating to the contents or display of the sales cells, they just contain the sales values straight from the query, and I've tried deleting the .rdl.data file with no effect.
Does anyone have any experience of this happening or suggestions of where to start to troubleshoot it?
Thanks for reading, hopefully it makes sense
