Ranking unique values by giving same rank to all duplicates

[ksrini]

Hi,

I have to rank/index unique values in column which has year-week combination which goes like 2015-01, 2015-02..... 2015-52, 2016-01...to say 2020-30. Per each week, there are several entries, so i need to assign same rank irrespective of the number of duplicates. I tried RankEQ but i could not get it. Can you please suggest any ideas ? 

Thanks,

Srinivas

Hi @ksrini ,

You may try to use RANKX function. Since you have a year-week combination, there may be a column for the number of weeks and a column for the number of years. I will use these two columns for sorting. If not, it doesn't matter, you can follow the steps below.

1.I have a dataset which has the Date column and the Sales column. Create calculated columns as follows to get year-week combination.

WEEKNUMBER = WEEKNUM([Date],2)

YEAR = YEAR([Date])

YEARWKKE = [YEAR]&"-"&[WEEKNUMBER]

2.Now create other calculated columns to get ranking.

RANKYEAR = RANKX(ALL('Table'),[YEAR],,ASC,Dense)

RANKWEEK = RANKX(ALL('Table'),[WEEKNUMBER],,ASC,Dense)

RANKXYEAR&WEEK = RANKX ( ALL ( 'Table' ), [RANKWEEK] + [RANKYEAR] * 100,, ASC, DENSE )

You can check more details from here.

Brilliant solution @Anonymous. Really appreciate for the details and the example. It worked perfectly across all duplicates. I did try Rankx earlier itself but we need to standardize the two fields Year, Weeknum to get correct rank. Thanks for your help.
