How to calculate total 2 weeks from a calculated measure?

milkynight — Thu, 15 Jul 2021 13:00:18 GMT

Hi all,

I have 2 tables:

Table 1: Week, National SOM (National SOM is a calculated measure)

Table 2: Week, Sort

I want to calculate total of every 2 weeks, for eg:

Jul21 W1 + Jul21 W2 = 4.5+4.6 = 9.1

Jun21 W4 + Jul21 W1 = 4.6+4.5=9.1

My current calculation doesn't work for National SOM as a measure (col Total 2W in the first screenshot). I appreciate your help to advise me what I can do in this situation? Thank you.

Total 2W = CALCULATE ( 'Table 1'[National SOM], FILTER ( ALL ( 'Table 2'), 'Table 2'[Sort] >= MAX ( 'Table 2'[Sort] ) -1 && 'Table 2'[Sort] <= MAX ( 'Table 2'[Sort] ) ) )

// You must have proper relationships // in place, e.g., the table with weeks // must be connected to your fact in a // one-to-many fashion. [Total 2W] = var MaxWeekVisible = MAX( Weeks[Sort] ) var Result = CALCULATE( // You must never precede a measure // with the name of the table it's // hosted in. On the other hand, columns // must always be preceded by the // table name. [National SOM], MaxWeekVisible - 1 <= Weeks[Sort], Weeks[Sort] <= MaxWeekVisible, ALL( Weeks ) ) return Result // If the above does not work, you have // to show what your [National SOM] measure // looks like because it seems to be flawed // as it does not aggregates across many // weeks, which stems from the measure's values // you've shown. Please show the measure // and the model. And please name your objects // something that is meaningful. Also, // it should not be 'Sort' but something like // WeekID. In formulas do not calculate the // same things many times over because this // has the potential to slow down the code. // If you have a value and need to use it in // different places---see for example: // MAX ( 'Table 2'[Sort] )---capture the value // in a variable and use the variable from then // on wards (variables are static, they don't // change once they've been evaluated). // Please read this guide and follow it: // https://www.sqlbi.com/articles/rules-for-dax-code-formatting/
