How Can I Apply Dynamic Sorting For Columns In Matrix Reports

Hi,

We have a matrix report which displays columns in a default sorting order. This report columns vary dynamically depending on the user input.

e.g. If user wants to see the report for column Alfa, Beta , Gama then a report will be genarted with column Alfa, Beta , Gama sorted in alphabetical order.

Alfa
Beta
Gama

Y
10
4
5
6
However the users want the Columns to be sorted in the order which they provide the inputs e.g. if the user entered Gama, Alfa, Beta the report should display the columns in the same order instead of applying the default sorting order.

Gama
Alfa
Beta

Any thoughts on ways to achieve this in SSRS matrix report would really help.

Cheers,
Viv
