If - Then Statement

[arobinson]

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,

If

(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,

IF

(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,

If

(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))))))))))))

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 )
    )

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.
