Calculated Column from Related Tables

Hello Everyone,

 

I need your help with this , guys.

 

Lets say I have the following dataset:

 

 

Table1 & Table2 are linked together through Col1 (Many to Many relation)

I want to create a new calculated column in Table 2 that will do the folloiwng for each value in Table 2 ,Col1:[ Sum (Col2,Table 1) / Col2,Table2] * 100%

 

Accordingly, the calculated column (Col3) will look like this:

 

 

Note: I dont know why the defined relation is (Many to Many) even though all values in Col1 , Table2 are unique and not repeated!!!!!!!

 

Is it because of empty cell or null?!

    Hi AZL

     

    You can use the below measure, it is having the check for blanks in the IF statement in the result area.

     

    Col3 = var _sumcol2=CALCULATE(SUM(Table1[Col2]),FILTER(Table1,Table1[Col1]=Table2[Col1]))
var _T2Col2=Table2[Col2]
var _result=_sumcol2/_T2Col2*100
Return 
IF(ISBLANK(_result),0,_result)

    If this helped you, please mark this post as an accepted solution and like to give KUDOS .

    Hi AZL

     

    Your guess about the many to many seems to be 100% accurate, it is because of null or blank values in the table.

     

    You can remove the null values in use the below DAX to create a column

     

     

    Col3 = var _sumcol2=CALCULATE(SUM(Table1[Col2]),FILTER(Table1,Table1[Col1]=Table2[Col1]))
var _T2Col2=Table2[Col2]
Return 
_sumcol2/_T2Col2*100

     

     

    You can see the attached pbix file.

      Thank you so much for the solution.It works well with me.

       

      But I have one more porblem. As you notice in attached file the values for "D & E & F" are empty eventhough it should be zero (since there's no value for these items in Table 1).How can I fix this problem??
