Average Last 6 months accumulated

[Syndicate_Admin]

Hello dear community, I come to you so you can help me with this DAX calculation.

I need a Calculated Column that shows me:

• the average of the last 6 months accumulated for each collaborator (in case the collaborator appears > = 6 times in the year);
• or in case the collaborator in the period of the current year appears less than 6 months, which shows the average based on the number of months that the collaborator has been in the company in the current period, for example:

Filtered Year: 2021
Current month: May2021 (5)
Age of the collaborator to May2021: 3 months (that is, the collaborator appears 3 times until May, if in June he becomes active, the collaborator when we are in June then will appear 4 times, and so on)

Then the average will be = (Sea + Apr + May)/3

Also consider, I already have a calendar table in my Power BI.

Here I have an example sample of what exactly I want (column "Average Last 6 months), you can download the file here:

I also leave the estracto here:

I read them, I hope you can help me as soon as possible. and thank you very much in advance.

Please create the following measure:

Measure = CALCULATE(AVERAGE([Compensation]),FILTER(ALLSELECTED('Table'),[Date]<=MAX([Date])),DATESINPERIOD('Table'[Date],MAX([Date]),-6,MONTH))

@Syndicate_Admin , Try a measure with date table, that would be better

Rolling 6= CALCULATE(Average(Table[compensation]),DATESINPERIOD('Date'[Date ],MAX('Date'[Date ]),-6,MONTH))

or

Rolling 6= CALCULATE(AverageX(values('Date'[Month year]),calculate(sum(Table[compensation]))),DATESINPERIOD('Date'[Date ],MAX('Date'[Date ]),-6,MONTH))
