Issue:
You receive an Error 13 Type Mismatch when trying to print reports in Dynamics Report Manager.
Resolution:
This error occurs when the parameters in the report do not match the setup in DRM. Open the report and count the number of parameters, and note their data types (string, date, boolean, etc.) in order. Then, in DRM Report Maintenance, make sure you have the same number of parameters set up and that the data types match. If you are using a SQL stored procedure, the SQL stored procedure parameter count must also match, as well as the data types.
