Power BI Measure - Summarize distinct values

[Thumper369]

I am trying to find the sum for defective effort but I need it to only sum distinct WorkItemId where Links.TargetWorkItem.WorkItemId is not blank

Measures I currently have:

Defective Effort = CALCULATE(SUM('Work items with direct links'[Effort]),NOT(ISBLANK('Work items with direct links'[Links.TargetWorkItem.WorkItemId])))

For the Sum in the table below (and in the chart) I am wanting the total to be 31 not 35, The Effort for ID 10829 is Getting counted twice

Thanks for the help.  I have searched for a few hours and can not find one that is workign for me.

The problem I was having turned out to be the relationship betwen two tables.  Created a table with only one entry for each sprint # then tied all the tables back to that table with a 1:many instead of many:many.  This resolved the problem.  

Thanks everyoe for your help.

Hi @Thumper369 ,

Here's the solution.

1.The dummy data I created.

2.Create a measure to calculate the Defective Effort.

Defective Effort =
CALCULATE (
    SUM ( 'Work items with direct links'[Effort] ),
    FILTER (
        ALLSELECTED ( 'Work items with direct links' ),
        [ID] = MAX ( 'Work items with direct links'[ID] )
            && [Links.TargetWorkItem.WorkItemId] <> BLANK ()
    )
)

3.You can see that the total in the table is incorrect, so we just need to create a new measure to add them correctly.

4.The new measure.

Total = 
VAR _table =
    ADDCOLUMNS (
        VALUES ( 'Work items with direct links'[ID] ),
        "DE", [Defective Effort]
    )
RETURN
    SUMX ( _table, [DE] )

If you're still confused, please provide some dummy data and expected results.

@Thumper369 , Try a measure like

sumx(summarize('Work items with direct links','Work items with direct links'[Links.TargetWorkItem.WorkItemId],'Work items with direct links'[Effort]), [Effort])

or

sumx(summarize('Work items with direct links','Work items with direct links'[Links.TargetWorkItem.WorkItemId],"_1", max( 'Work items with direct links'[Effort])), [_1])

Sorry, neither of those work.  I tried them on their own, but they did not constarin it to only rows that had  targetworkItem.WorkItemId.   
I tried them in my measurement but they still do not exclude the duplicate of 108829
