Today I have small tip. Let me share a scenario. Suppose you have to display Customer group as report level group and customer at detail level who did purchased products from your organization in given period of time.
Serial number on detail level can be achieved by RowNumber(“Scope Name”)
But serial number shown on Group level is tricky because RowNumber not works there. For example in above mention scenario, Client wants serial number on Customer Group instead of Customer at detail level.
I used following single line SSRS expression helps me to achieve this.
