Have you installed one of the new Report Builders-- version 2 or version 3-- and can't get AX to launch it?
This posting addresses the issue and walks you through the steps to point AX to the new version.
The first step is that you will need to get Report Builder 2.0 or 3.0 installed on your report server. You should be able to access the Report Builder through the Internet Explorer first. In addition, you should already be able to access Report Builder 1.0 from AX. If you don't have this working you will need to revisit the installation guides. Once you have Report Builder 1.0 working through AX and the newer version of Report Builder working outside of AX than you can make the following changes.
Try this in a Test Environment prior to performing this on a production environment and as always make sure you have good backups.
Get into Dynamics AX and access the AOT.
1) Locate the SRSConfiguration class (Classes >>SRSConfiguration).
2) Edit the getReportBuilderUrl method with the following changes:
3) Save the method.
4) Locate the SRSReportBuilder class (Classes >> SRSReportBuilder).
5) Edit the Invoke method to have the following changes:
6) Save the Method.
7) Compile the changes and test.
