Is it possible to develop or customize SSRS report in 2012 without Visual Studio installed? (If so, we'd like to use Report Bulider instead.)
You can modify the existing SSRS Reports with Report Builder but, You can't create the new SSRS Reports without Visual Studio.
What Alvin says, plus;
- You can modify reports in another environment where you have Visual Studio installed and move the modified report between environments using XPO Export and Import.
- You can update an existing SSRS Report by uploading a new RDL directly in the Report Server Manager Web interface, (but the AOT will be unaware of the changes and a redeploy from AX will overwrite).
I strongly recommend making sure all AX related SSRS reports are represented within the AOT with the latest revision of any changes.
