Help with RANX formula and date buckets

[indyb]

Hi all, 

I have a table containing complaints recieved. These have a date attached to them which has been broken down in the table in a heirarchical structure. 

I am trying to bucket these dates into the following buckets :

0 - 4 weeks 

4 - 8 weeks 

8 + Weeks 

I have taken the month number and Ranked them using the following formula : 

T_Date = RANKX(DateTable,[Month Num],,ASC,Dense)-1

From there, I have bucketed them using the following : 

Open Complaints Buckets = If(DateTable[T_Date]=1, "0 - 4 Weeks",

If(DateTable[T_Date]=2, "4 - 8 Weeks", "8+ Weeks"))

Unfortunately when doing the above, i get the following :

Please can you advise where I have gone wrong and how to correct this? 

Regards, 

Indy

Hi @indyb 

Please check If this result is expected.

Create a new table

date =
ADDCOLUMNS (
    CALENDARAUTO (),
    "year", YEAR ( [Date] ),
    "month", MONTH ( [Date] ),
    "monthno", FORMAT (
        [Date],
        "yyyymm"
    ),
    "monthname", FORMAT (
        [Date],
        "Mmm yyyy"
    )
)

Add calculated columns

rank = RANKX(FILTER('date','date'[Date]<=TODAY()),[monthno],,DESC,Dense)-1

rank bucket = SWITCH([rank],1,"0~4 weeks",2,"4~8 weeks","8+weeks")

Best Regards
