Help with Time difference between multiple rows & Index

[gunner]

Hi guys, I had previously marked this as solved but I have noticed something which is throwing off my calculations. I am using an
index field to calculate the difference between the times of an item being acquired and it being released.

The query language for the index is from earlier in this thread and it wokrs fine until an item is acquired and released at the
exact same time for a user. The Index assigns both actions the same value, which throws out the calculations quite substantially.

Example in the image below, where the last 2 lines an item is acquired and released at same time and both are assigned the same
index value (17). Ideally i want the index to assign the value of 17&18, or even just disregard this altogether as the
corresponding time value would be zero. I have tested it by manually deleting those last 2 entries from the datasource and the
calculations are perfect. I need same values to be removed, or assigned the correct index value. Thank you if you can help.

Index Query:

Index = 
IF (
    OR ( 'OpenLicenseUsage-9601427'[Action] = "Released", 'OpenLicenseUsage-9601427'[Action] = "Acquired" ),
    RANKX (
        FILTER (
            ALL ( 'OpenLicenseUsage-9601427'),
            OR ( 'OpenLicenseUsage-9601427'[Action] = "Released", 'OpenLicenseUsage-9601427'[Action] = "Acquired" )
                && 'OpenLicenseUsage-9601427'[User] = EARLIER ( 'OpenLicenseUsage-9601427'[User] )
        ),
        'OpenLicenseUsage-9601427'[Timestamp (UTC)],
        ,
        asc
    )
)

Hi @gunner,

I would suggest you add an index in the Query Editor and then make a little change of your formula. 

Index = 
IF (
    OR ( 'OpenLicenseUsage-9601427'[Action] = "Released", 'OpenLicenseUsage-9601427'[Action] = "Acquired" ),
    RANKX (
        FILTER (
            ALL ( 'OpenLicenseUsage-9601427'),
            OR ( 'OpenLicenseUsage-9601427'[Action] = "Released", 'OpenLicenseUsage-9601427'[Action] = "Acquired" )
                && 'OpenLicenseUsage-9601427'[User] = EARLIER ( 'OpenLicenseUsage-9601427'[User] )
        ),
        'OpenLicenseUsage-9601427'[Index],
        ,
        asc
    )
)

Best Regards,
