RANKX seems to be ranking on absolute value

eeurton — Fri, 31 Jan 2020 18:05:11 GMT

I am using the formula below to create a ranking measure

Rank AvT = RANKX(

FILTER(

ALL('Fact - CIM Food Usage Summary'),

'Fact - CIM Food Usage Summary'[CONCEPT] = EARLIER('Fact - CIM Food Usage Summary'[CONCEPT])

&& 'Fact - CIM Food Usage Summary'[YR_MO_NBR] = EARLIER('Fact - CIM Food Usage Summary'[YR_MO_NBR])

&& 'Fact - CIM Food Usage Summary'[CNT_TYP_CD] = EARLIER('Fact - CIM Food Usage Summary'[CNT_TYP_CD])

&& 'Fact - CIM Food Usage Summary'[AVT_INCL_FLG] = "Y"

[AVT_PCT_USE],,ASC,Dense)

It is not quite working as expected, the issue is that it seems to be ranking on absolute value rather than the actual value (see below) I would expect the -1.3% to be ranked first, not third, can someone offer a solution?

Hi eeurton ,

I love RANKX questions (I don't know why, I just like the logic I guess :P) but they are very hard to trouble shoot without having any data to replicate the issue. For example, you are using a measure to rank rows in a calculated column (I assume based on your EARLIER() statements), but you didn't give us the DAX of said measure.

If at all possible, would you be able to share either the original PBIX or (if that contains confidential information) a PBIX with dummy data that still reflex your issue? If you don't want to share publicly, you can share by PM and I will have a look tomorrow. I'm sure I can figure this out for you 🙂

Kind regards

JarroVGIT thanks for responding to my post! The measure that I am ranking (AVT_PCT_USE) is a calculated column in one of my tables, the formula is below:

if [CNT_TYP_CD] = "PERIOD" then (([OVRD_VAL_VRNC_AMT] + [SAP_COGS_EXP_AMT] - [VAL_ACT_UNIT_USED_AMT] - [SAP_SE_AMT] - [ROCK_SE_TOTAL_FOOD_COST]) / [SAP_COGS_EXP_AMT]) else [OVRD_VAL_VRNC_AMT] / [VAL_ACT_UNIT_USED_AMT])

if we need a pbix with data I will need to get back to you on Monday as I will need to restrict the model down to a historical period that is not sensitive and then refresh the data.

JarroVGIT , thanks again for responding to my post, I was able to finally figure out the issue (user error). The problem was that the measure I am ranking was mistakenly set as a "text" data type, once I changed that to a decimal number data type the RANX measure started working as expected.
