Earlier is not 0

[Anonymous]

Is it possible using earlier with something like "not null" instead of using -1 or -2 etc.

I dont want that it writes just the data wich is in the previous field , but I want that it writes the first previous data wich is not 0 for example.

My Formula should be something like this, but it doesnt work, cause I can`t reference to its own ("Downtime"

Downtime = IF('runtime nagios_statehistory (2)'[eventtype]=2;2; IF('runtime nagios_statehistory (2)'[eventtype]=3;3; (CALCULATE(MAX('runtime nagios_statehistory (2)'[Downtime]);FILTER('runtime nagios_statehistory (2)';'runtime nagios_statehistory (2)'[object_id]=EARLIER('runtime nagios_statehistory (2)'[object_id])&&'runtime nagios_statehistory (2)'[Group Ranke]=EARLIER('runtime nagios_statehistory (2)'[Group Ranke]) -1)))))

Someone has an idea?

HI @Anonymous ,

AFAIK, current power bi does not support add DAX formula and invokes its previous result for calculating. I'd like to suggest you split this formula to multiple columns to do formatting on 'Type' value.

TypeGroup =
IF (
    'Table'[eventtype] IN { 2,3 };
    'Table'[eventtype]
)
	
Downtime =
IF (
    'Table'[TypeGroup] <> BLANK ();
    'Table'[TypeGroup];
    CALCULATE (
        MAX ( 'Table'[TypeGroup] );
        FILTER (
            'Table';
            'Table'[object_id] = EARLIER ( 'Table'[object_id] )
                && 'Table'[Group Ranke]
                    = EARLIER ( 'Table'[Group Ranke] ) - 1
        )
    )
)
