Oftentimes when I press the Refresh button and proceed to select the criteria in the Prompts dialog box, I get the following error:
An internal error occurred while calling 'processDPCommandsEx' API. (Error: ERR_WIS_30270)
If I press the OK button, press the Refresh button again, and select the same criteria again, no error occurs and the report displays properly.
I've not found any pattern for -- nor cause of -- this issue. What could be causing it? How do I resolve it so that my end users don't see it?
