MAA - Calculation

[Anonymous]

Dear all,

I'm trying to calculate the MAA (Moving Annual Average) value - but I would need your help on this KPI & DAX language.

Data are like this:

-> Conformity level (Grade A = OK/NON OK per scan/factory/etc.).

So I would need to calculate the average of grade A on the last 13 periods. 

year	CONFORMITY	Period	Factories
2020	OK	P13	RCA
2020	OK	P13	RCA
2020	OK	P13	RCA
2021	OK	P01	RFT
2021	WRNG_NOK	P01	RFT
2021	OK	P02	RNI
2021	OK	P02	RNI
2021	OK	P02	RNI
2021	OK	P02	RNI
2021	OK	P02	RNI

% Grade A from the last 13 periods -> Total Count OK/(Conform + WRNG + NON OK)*100 from the last 13 periods

Above is an exemple (the 13 periods are missing) -> expected results = 90 %

Thanks for your help

Hi @Anonymous ,

The basis for processing the same ranking, skip stands for sparse ranking, and the next ranking is equal to the number of all previous rankings + 1; dense stands for dense ranking, which only accumulates the ranking, regardless of the number. Use skip by default. ASC stands for ascending order, DESC is used by default.

I did a test, it can be used as a reference:

M1 = RANKX('Table',[Value],,ASC,Dense)

M2 = RANKX('Table',[Value],,ASC,Skip)

For specific formulas, please refer to the blog link provided by me:RANKX – DAX Guide

Hello

If you take my example above, what do you mean by "value"?

Thanks

Hi @Anonymous ,

The "value" field is the column I need to sort.

Hello,

And more baiscally can I use this formula:

YTD 2021 = Divide(CALCULATE(COUNTROWS(rclms_qa), FILTER(rclms_qa,rclms_qa[CONFORMITY]="OK"&&rclms_qa[Mars Year]=2021)),CALCULATE(COUNTROWS(rclms_qa), FILTER(rclms_qa,rclms_qa[Mars Year]=2021)))*100

And get the results (adding a DAX formula) of the last 13 periods (from today until the last 13 periods).

Thanks

Hi @Anonymous ,

Yes, your formula is also a good way. If the problem has been solved or my reply provided you with help, you can mark it as the correct answer to to help the other members find it more quickly.😊

@Anonymous , First create a separate year period table with period rank column and join both on yearperiod combine column

Period Rank = RANKX(all('Period'),'Period'[year period],,ASC,Dense)

Then you can measure like
This Period = CALCULATE([% Grade A ], FILTER(ALL('Period'),'Period'[Period Rank]=max('Period'[Period Rank])))
Last Period = CALCULATE([% Grade A ], FILTER(ALL('Period'),'Period'[Period Rank]=max('Period'[Period Rank])-1))

Last 13 Period = CALCULATE([% Grade A ], FILTER(ALL('Period'),'Period'[Period Rank]>=max('Period'[Period Rank])-13 && 'Period'[Period Rank]<=max('Period'[Period Rank])))

Hello,

What does it mean -> ASC,Dense?

Thanks
