Unable to build SSRS reports in Visual Studio after adding a new field in temp table

Hi All,

I am trying to modify Inventory on hand SSRS report in AX 2012 R2. I need to add one column, so for this purpose I added a new field in temp table, modified the DP class and then refresh the dataset in Visual Studio, added the field in AutoDesign. Now when I am trying to build the project, I am getting the below error in VS:

Error 1 System.InvalidOperationException: Object is currently in use elsewhere.

I already tried to restart SQL server reporting services and AOS but still getting the same error. Can anyone please let me know how to resolve this error, as I have already spent hours and hours trying to resolve this issue.
