    untested, but try something like this:

    AVERAGEX(

        	FILTER(
        	    ALL( 'Calendar'[date] ),
        	    'Calendar'[date] >= varReportDate-14&&'Calendar'[date] < varReportDate
       	 	)
    	)
 	VAR Sumplus14=
    	CALCULATE(
        	SUM( 'Sales'[Sales] ),
        	FILTER(
            		ALL( 'Calendar'[date] ),
            		'Calendar'[date] <= varReportDate+14&&'Calendar'[date] > varReportDate
        	)
    	)
 	RETURN DIVIDE(Sumplus14,Summinus14)

Hi jayjay0306 

 

I understand your requirement, but according to your description, your data comes from three tables, I am not quite sure about the table structure of your three tables, can you provide me with this information? You can refer to the following link to provide the data: How to provide sample data in the Power BI Forum - Microsoft Fabric Community

Or show it as a screenshot or excel. Please remove any sensitive data in advance.
