If you have installed Reporting Services on multiple servers, you must specify which server is the default Reporting Services server. Use the following procedure to do so.
Complete the procedure using your Microsoft Dynamics AX client.
Open the Default Report Serversform ( Microsoft Dynamics AXmenu > Tools> Business Intelligence (BI) tools> Default Report Servers).
Select a default server to publish report models to.
If a report server is not specified in the Destination server IDfield of the Model Generation Optionsform, models will be published to the server that you specify here.
Select a default server for report libraries.
