    Hi,

     

    This calculated column formula in Table1 works fine

     

    =CALCULATE(MIN(Table2[Repair_Date]),FILTER(Table2,Table2[Serial_Number]=EARLIER(Table1[Serial_Number])&&Table2[Repair_Date]>EARLIER(Table1[Call_Date])))

    Hi,

     

    Try this calculated column formula

     

    =if(ISBLANK(COUNTROWS(FILTER(Table1,Table1[Serial_Number]=EARLIER(Table1[Serial_Number])&&Table1[Call_Date]>EARLIER(Table1[Call_Date])))),CALCULATE(MIN(Table2[Repair_Date]),FILTER(Table2,Table2[Serial]=EARLIER(Table1[Serial_Number])&&Table2[Repair_Date]>EARLIER(Table1[Call_Date]))),if(CALCULATE(MIN(Table1[Call_Date]),FILTER(Table1,Table1[Serial_Number]=EARLIER(Table1[Serial_Number])&&Table1[Call_Date]>EARLIER(Table1[Call_Date])))-[Call_Date]<=30,BLANK(),CALCULATE(MIN(Table2[Repair_Date]),FILTER(Table2,Table2[Serial]=EARLIER(Table1[Serial_Number])&&Table2[Repair_Date]>EARLIER(Table1[Call_Date])))))

     

    Hope this helps.

Hi Ashish_Mathur, Thanks a Lot!
Your calculated column formula works.

 

Taking the opportunity.

In your formula, Is it possible I can insert a conditional, to not return duplicates [Repair_Date] where the last [Call_Date] is smaller than 30 days?

Like the Example below:
