DAX Calculate IN

[Anonymous]

Hello, I'm pretty new to writing DAX.

I've created Measure that CALCULATE SUM of VALUE IN specified PERIOD

Here is a formula:

Plan III'18 = CALCULATE(
   SUM(Table[Plan]);
   Table[Quarter] IN { "III'2018" }
)

Its calculate sum of values from PLAN = III'2018

This formula works fine, when user selected in slicer Quarter = IV'2018 he could find values of PLAN for Selected QUARTER and see values for Prev Quarter

But I want to change behaviour of this Measure to calculate always sum of values from Previous Quarter

For example, if user selected in slicer III'2018 (instead of IV'2018) it will show him values for II'2018 (-1 QUARTER)

What I have in "Table"

Columns names

• Subject (char)
• Quarter (char)
• Plan (int)
• Quarter Prev (char) 

Thanks in advance

Hi @Anonymous,

One sample for your reference.

1. Create a calculated table as below.

Table = UNION(VALUES(Table1[Quarter]),VALUES(Table1[Quarter Prev]))

2. Creat a measure to get the result as we need.

Measure = 
VAR _sele =
    SELECTEDVALUE ( 'Table'[Quarter] )
VAR _pre =
    SWITCH (
        _sele,
        "IV'2018", "III'2018",
        "III'2018", "II'2018",
        "II'2018", "I'2018",
        "I'2018", "IV'2017"
    )
RETURN
    IF (
        ISBLANK ( _sele ),
        BLANK (),
        CALCULATE ( SUM ( Table1[Plan] ), FILTER ( Table1, Table1[Quarter] = _pre ) )
    )
