I cannot understand why nobody is not answering to me. Seems very strange that such an important function doesn’t work. So I wrote here to understand if is there an easy workaround for it.
From my point of view, the only workaround is to create a Script Report, but I think that a function like this should work also with Report Builder or Query Report. Another workaround is to use the ORDER BY clause in the SQL but if you click on the Column Label it orders in the wrong way.
I already have a support contract. I opened this post because I thought that could be useful for the community and I wrote that because I was amazed because such a function had not attracted the attention of other users or developers.
