HI , 
I have report based on data module but function ParamValue or ParamDisplayValue not recognized ? Cognos Analytics 11.1.3 ? is there any solutions ? 
			
			
			
				Both are in the report functions folder of the layout calculation editor.  
Could go elaborate about what problem you are encountering please.
			
			
			
				if my source is data module "Undefined function: 'ParamValue'. This function is neither a registered temporary function nor a permanent function registered in the database 'default'."
