RANX Issues

[KeatonO]

Hello there, this is my first post. I have spent hours trying to figure this out. I have watched videos and tried all kinds of variations myself. For some reason, I can only get a 1 or a 2 to return on my rank. My assumption is that my sum formula is too complex or that there is an issue because my filter is a lookup from another table. 

I need to rank based on sum revenue, sum dials, and sum talktime, all separate. Looking at revenue specifically, here is my formula.

Revenue Rank = RANKX(ALL('Invoiced Sales Data - ZCA_ProfitabilityAnalysis'[Role]),[Rep Revenue])

Role is a lookup from a roster table 

Rep Revenue is a calculate sum with multiple filters.

 Name is also a lookup from the roster table

I am trying to produce 

Name            Revenue        Rank

John Doe        5,000             1

Alex Danger    4,000             2

etc 

and highlight the bottom 20%

I can stack rank the revenue to show what I need but need a rank so I can later add the rankings and divide by total ranks to get a productivity score. the issue is, I am stuck on step one and cannot for the life of me return anything other than a 1 or 2 for every entry. Joe and Alex will both be a 1 or a 2. 

I have tried 

Revenue Rank = RANKX(ALLSELECTED('Invoiced Sales Data - ZCA_ProfitabilityAnalysis'[Role]),[Rep Revenue])

Revenue Rank = RANKX(ALL('Invoiced Sales Data - ZCA_ProfitabilityAnalysis'[Role]),[Rep Revenue],,DESC, Dense)))

Revenue Rank = RANKX(ALL('Invoiced Sales Data - ZCA_ProfitabilityAnalysis'[Role]),CALCULATE([Rep Revenue]))

Revenue Rank = RANKX(ALL('Invoiced Sales Data - ZCA_ProfitabilityAnalysis'),[Rep Revenue])

And just about every variation between these possible I can think of.

This is taking much longer than I expected and am now nearing my deadline, please help.

Difficult to troubleshoot without example data. Perhaps this will help: https://community.powerbi.com/t5/Quick-Measures-Gallery/To-Bleep-with-RANKX/m-p/1042520#M452

The most important parts are:
1. Sample data as text, use the table tool in the editing bar
2. Expected output from sample data
3. Explanation in words of how to get from 1. to 2.

Thank you for the valuable links. Hopefully this will help you further. I did try the suggestions you provided with the "what the hell ranx" formulas to no avail.

Sorry, the invoiced sales data is also a line by line detail of who placed what order and the amount the order was sold for. This is the current formula being displayed in the image above.

I FIGURED IT OUT!!!!! Oh my gosh, such relief right now, it was such a simple fix. 

I changed the grouping from role to name and then added a filter to the visual for the group I was looking for. Thanks for all of your help. 🙂
