Add backlog value before calculate

[Alain06]

Good morning

I'm trying to calculate a ticket backlog starting at 01/01/23, with open ticket, closed ticket and balance....
everything is ok for that, there are various examples ....

My problem is that my balance was greater than 120 on 01/01/23 and I can't add that to my automatic calculation

Can you help me

With the Data ....

I would like to add 120 to my starting backlog

Tickets Créés = CALCULATE(COUNT('DataRM_GIDN'[TicketRM]),USERELATIONSHIP('DataRM_GIDN'[Créé],'TBCal'[Date]) )

Tickets Cloturés = CALCULATE(COUNT('DataRM_GIDN'[TicketRM]),USERELATIONSHIP('DataRM_GIDN'[Fermé],'TBCal'[Date]),not(ISBLANK('DataRM_GIDN'[Fermé])))

 

Backlog =

CALCULATE(

    COUNTx(

        FILTER(

            'DataRM_GIDN',

            'DataRM_GIDN'[Créé]<=max('TBCal'[Date]) && (ISBLANK('DataRM_GIDN'[Fermé])

            || 'DataRM_GIDN'[Fermé]>max('TBCal'[Date]))

        ),

        ('DataRM_GIDN'[TicketRM])

    ),

    CROSSFILTER(

        'DataRM_GIDN'[Créé],'TBCal'[Date], None

    )

)
