If - Then Statement

arobinson — Mon, 22 Jun 2020 19:41:38 GMT

I am working on a long IF statement. I am trying to put weights on this statment. When I am running this, it slows the table down to a crawl.

Total % = If

(SELECTEDVALUE('Staffing Name Page'[Region]) = "D1",

(([Communication Total] * .6) + ([Productivity Total] * .4)) / 1,

If(SELECTEDVALUE('Staffing Name Page'[Region]) = "D2",

(([Communication Total] * .6) + ([Productivity Total] * .4)) / 1,

If(SELECTEDVALUE('Staffing Name Page'[Region]) = "D3",

(([Communication Total] * .6) + ([Productivity Total] * .4)) / 1,

(SELECTEDVALUE('Staffing Name Page'[Region]) = "DG1",

(([Communication Total] * .6) + ([Productivity Total] * .4)) / 1,

If(SELECTEDVALUE('Staffing Name Page'[Region]) = "DG2",

(([Communication Total] * .7) + ([Productivity Total] * .3)) / 1,

If(SELECTEDVALUE('Staffing Name Page'[Region]) = "DG3",

(([Communication Total] * .6) + ([Productivity Total] * .4)) / 1,

(SELECTEDVALUE('Staffing Name Page'[Region]) = "A1",

(([Communication Total] * .8) + ([Productivity Total] * .2)) / 1,

If(SELECTEDVALUE('Staffing Name Page'[Region]) = "A2",

(([Communication Total] * .8) + ([Productivity Total] * .2)) / 1,

If(SELECTEDVALUE('Staffing Name Page'[Region]) = "A3",

(([Communication Total] * .8) + ([Productivity Total] * .2)) / 1,

(SELECTEDVALUE('Staffing Name Page'[Region]) = "AH1",

(([Communication Total] * .6) + ([Productivity Total] * .4)) / 1,

If(SELECTEDVALUE('Staffing Name Page'[Region]) = "AH2",

(([Communication Total] * .4) + ([Productivity Total] * .6)) / 1,

If(SELECTEDVALUE('Staffing Name Page'[Region]) = "AH3",

(([Communication Total] * .3) + ([Productivity Total] * .7)) / 1))))))))))))

1) learn how to use variables

2) do not use multiple nested IF, use SWITCH

Create a reference table that holds the [Communication Total] and [Productivity Total] coefficients for each region.

Link that table into your data model and let the data model do all the work.

Hi arobinson ,

Apart from the suggestions below, you can use this simplified version of DAX code.

Measure = VAR _selvalue = SELECTEDVALUE ( 'Staffing Name Page'[Region] ) RETURN SWITCH ( TRUE (), _selvalue = "D1" || _selvalue = "D2" || _selvalue = "D3", ( [Communication Total] * .6 ) + ( [Productivity Total] * .4 ), _selvalue = "A1" || _selvalue = "A2" || _selvalue = "A3", ( [Communication Total] * .8 ) + ( [Productivity Total] * .2 ), _selvalue = "DG1", ( [Communication Total] * .6 ) + ( [Productivity Total] * .4 ), _selvalue = "DG2", ( [Communication Total] * .7 ) + ( [Productivity Total] * .3 ), _selvalue = "DG3" || _selvalue = "AH1", ( [Communication Total] * .6 ) + ( [Productivity Total] * .4 ), _selvalue = "AH2", ( [Communication Total] * .4 ) + ( [Productivity Total] * .6 ), _selvalue = "AH3", ( [Communication Total] * .3 ) + ( [Productivity Total] * .7 ) )
