Distinct Count when looking at multiple fields in table

[efowler]

Hello...  I have a long standing challange to properly calucate what I call "Distinct Repair".   I have a sample data table attached which shows the overall data and column E shows what would be considered a Count = 1.  My notes are below and this data is related to repair data on a product. 

Goal = To count distinct repairs in which there are more than one rows (unique Claim #) for the same product on the same date with same repair part. 

Challange = A single repair can show in the data set as two rows each with a unique claim #.  When the Product Serial #, PFP, and Repair Date are all the same between the two row it should be counted a Distinct Repair = 1

Any ideas on how to write the DAX for this?

Hi, @efowler 

Please check if formula below could help:

Result =
VAR min_Claim =
    MINX (
        FILTER (
            ALL ( 'Table' ),
            'Table'[Product SN] = EARLIER ( 'Table'[Product SN] )
                && 'Table'[PFP] = EARLIER ( 'Table'[PFP] )
                && 'Table'[Repair Date] = EARLIER ( 'Table'[Repair Date] )
        ),
        'Table'[Claim #]
    )
RETURN
    IF ( 'Table'[Claim #] = min_Claim, 1, BLANK () )
