Let say that we need the following transformation in SSRS report:
One of the tools to do this is List.
I will explain only the tricky part and will give the .rdl in the end.
Drag-and-drop List in the report body:
Right click the top left corner of the list –> Tablix Properties…:
Attach to the dataset that feeds the report:
Open Group Properties in Row Groups:
Add the group:
Sort the report:
Add two textboxes and the table to the list:
The .rdl (built in Visual Studio 2019):
