Increment variable after condition

[Anonymous]

Hi Guys,

I need a help with the case below:

How to write it in Dax or Powerquery a code like this below:

Expected Result =

VAR V_ID = 1
RETURN

    if('Table'[OverflowAlarm] = 1 && 'Table'[Previus row] = 0, V_ID, 
        if('Table'[OverflowAlarm] = 0 && 'Table'[Previus row] = 1,    V_ID = V_ID +1 ,

           if ('Table'[OverflowAlarm] = 1 && 'Table'[Previus row] = 1, 'Table'[OverflowAlarm],0
)))

I have a table like that:

Time/date	Point_Id	Index	Duration	OverflowAlarm	Previus row
14/03/2018 23:45	PDD11148	78241	15	1
14/03/2018 23:30	PDD11148	78242	15	1	1
14/03/2018 23:15	PDD11148	78243	15	1	1
14/03/2018 23:00	PDD11148	78244	15	1	1
14/03/2018 22:45	PDD11148	78245	15	1	1
14/03/2018 22:30	PDD11148	78246	15	1	0
14/03/2018 22:15	PDD11148	78247	0	0	0
14/03/2018 22:00	PDD11148	78248	0	0	0
14/03/2018 21:45	PDD11148	78249	0	0	0
14/03/2018 21:30	PDD11148	78250	0	0	0
14/03/2018 21:15	PDD11148	78251	0	0	0
14/03/2018 21:00	PDD11148	78252	0	0	0
14/03/2018 20:45	PDD11148	78253	0	0	1
14/03/2018 20:30	PDD11148	78254	15	1	0
14/03/2018 20:15	PDD11148	78255	0	0	1
14/03/2018 20:00	PDD11148	78256	15	1	1
14/03/2018 19:45	PDD11148	78257	15	1	1
14/03/2018 19:30	PDD11148	78258	15	1	1
14/03/2018 19:15	PDD11148	78259	15	1	1
14/03/2018 19:00	PDD11148	78260	15	1	1

And that is the result that I need:

Point_Id	Index	Duration	OverflowAlarm	Previus row	Expected Result
PDD11148	78241	15	1		event 1
PDD11148	78242	15	1	1	event 1
PDD11148	78243	15	1	1	event 1
PDD11148	78244	15	1	1	event 1
PDD11148	78245	15	1	1	event 1
PDD11148	78246	15	1	0	event 1
PDD11148	78247	0	0	0
PDD11148	78248	0	0	0
PDD11148	78249	0	0	0
PDD11148	78250	0	0	0
PDD11148	78251	0	0	0
PDD11148	78252	0	0	0
PDD11148	78253	0	0	1
PDD11148	78254	15	1	0	event 2
PDD11148	78255	0	0	1
PDD11148	78256	15	1	1	event 3
PDD11148	78257	15	1	1	event 3
PDD11148	78258	15	1	1	event 3
PDD11148	78259	15	1	1	event 3
PDD11148	78260	15	1	1	event 3

Any help is welcome!

Thanks

Thanks for your response.

I am not a Power Bi expert, I've been working only few weeks with it. But, I couldn't see it working for me. And the function earlier doesn't work well... too many rows in the table, it runs forever... Any other solution?
