I found that it is nor possible to have horizontal scroll bar for dimensions but our client insists us to have it as we have many dimensions.
Please specify if there is any way to have horizontal scroll bar for the dimensions also.
It may be in the form of custom code also or any add-in that we can do.
There is currently no way to force a horizontal scroll bar. However, it you have more than 6 dimensions on your view, the dimensions may have started to have combined. You can increase the number of labels for a row without that happening by going to Analysis>Table Layout>Advanced... Then, increase the row labels.
Hope this helps a bit!
