I have an issue wherein SSRS Report in AX 2012 keeps on loading and encounter timeout in production environment. But in non-production environment, it can be generated within 1-2 minutes. Code and data is the same in both environments. I also conducted trace in both environment and compared them but couldn't find anything that could lead to the issue. I also tried to deploy the SSRS report, refresh caches via Tools > Caches (Refresh dictionary, data, elements, report server). The SSRS report uses SRSReportDataProviderBase
Any suggestions will be highly appreciated. Thanks.
