Parameter _reportName cannot be null or empty.

Recently came over a problem with running SSRS reports from AX 2012 (R2).

 This Infolog error message was presented immediately when trying to run a report:

Parameter _reportName cannot be null or empty.

 

The [CLASSNAME].[METHODNAME]() reflection API could not create and return the SrsReportNameAttribute object.

 

In this specific case it looks like an earlier full compile did not finish.

 

If you encounter this problem I would suggest that you first compile the class mentioned in the error message and see if this solves the problem. Then you should schedule for a new full compile of the application.
