Problem: Donors don't add up to the grand total, like the giving does. This is because a donor's age range is determined for each and every gift, based on the date of that gift, and over the course of a year a donor can cross ranges.

Request: I would like a DAX formula to limit donors to one range. In an ideal world, it would be based on which age range they fall in for the majority of the year, but I would settle for just arbitrarily keeping one of them. I believe in SQL you could go about this by partitioning and ranking. But then it failed in Excel, saying "summarizecolumns cannot have outside filter context. Note: You can partition the MaxAge by fiscal year as well if you like so that a donor can move between groups when viewing years separately.

Please refer to this article for more information on the differences and limitations of these functions in different environments. Note: This IN syntax above is a newer feature.

How to use RANKX in DAX (Part 1 of 3 – Calculated Columns)

You are more likely to get help if you provide a more descriptive title and include a sample of what your data table looks like. An mcve would be ideal. Thanks AlexisOlson. I was frustrated by the down votes, but maybe that explains it. I've edited the question to provide a different title and sample data.

It's always hard figuring norms in a new community. Your edit makes this a much better question! Active Oldest Votes. I think the simplest approach would be to create a couple of calculated columns to use instead.When I first started to play with DAX, one of the functions that seemed to confuse me more than it should, was how to add ranking to my data.

This is not a criticism of the documentation either. Probably more a reflection that I was too lazy to digest the information properly.

I have been meaning to write an explanation on how to use the RANKX function, in a way that I would follow — so if this is helpful to you then that would be great. One of the first traps to encounter when using this function is the function can be used in calculations for calculated columns as well as calculated measures. The trick is how you use the function in each scenario — and more importantly, what filters are going to be implicitly applied to the data the RANKX function actually uses.

I have deliberately added tied values to the data to allow exploring some methods for breaking ties later in this article. This can be a physical table, or it can be the output of a DAX function that returns a table.

If we pass our sample row dataset to the function, the code inside the RANKX function will loop 10 times once for each row in the table. The smallest number that could be generated is a 1, while the largest value that could be returned is a If we used a function to summarize the physical table, say to the distinct values of the Category column, the RANKX function will logically perform three loops.

This needs to be a single number — but can be the result of a complex calculation, although more often than not, it will likely be just the SUM over a column for a single or series of rows group together. You can write DAX calculation here that returns a single value. This optional parameter is a peculiar one. I will try to explain this in more detail at the end of the article, so until you actually know you need this parameter, I recommend you leave it blank.

This parameter has nothing to do with breaking ties. The sample data-set I use for this article deliberate has some ties so you can see what the RANKX function will return. To generate a new column that ranks the values in the My Value column against all other rows in the table, the following calculation can be used. That was easy! The values in the new column have values that correctly rank each row according to the My Value column.

The default is the larger numbers have a ranking. The last column now carries a value that ranks the table based on the My Value column but this time the smallest value has a rank of 1 and the ranking value increases. Note that the 3rd and 4th rows, share the same value in the My Value column, so therefore have the same Rank of 3. There are no rows with a rank of 4 with the next rank in the column being a 5. This is because there were 2 items tied for 3rd.

If there were 3 items tied for 3rd, then the next ranking would be 6. Sometimes you would like to rank the order of some items within a category.

In our data-set we have a Sub Category column and if the intention is to provide a column that shows the order of these within a Categoryrather than overall, the following code can be used. The new column now shows a ranking that resets for every Category. This seems quite repetitive but in actual fact, the DAX engine uses smart algorithms to execute the above pseudo logic quickly and efficiently — but it is helpful to understand the logical process, particularly when it comes to nested outer and inner tables.

Or said another way, the only way to break ties is to make sure there are no ties. Dates in DAX are simply integer values.Basically in a simplified way I have data per customer for differen periods, and I want to rank data based on a combination of this.

I can best explain by example, see the table for the result column 'Desired Rank' I am looking for. Go to Solution. Good points! View solution in original post. So it is not yet an excisiting column in my BI, just created it here to show what I mean. This looks like a nested index. Baskars solution is a DAX-version. I'm not aware of a possibility to create the Index-column in DAX. However I'm still struggeling. I have to do this in Powerpivot and not sure I can use the provided solutions.

Thanks for the points, please mark the corresponding reply as answer for help more people. Best Regards, Angelia. The time has come: We are finally able to share more details on the brand-new ranks coming to the Power BI Community!

Attached Files RankNoRepeats. Re: Eliminate Duplicates In Rank Formulas Thanks Martin, I must have copied and pasted the last formula in my test range instead of the first that should have been copied down I guess the OP figured it out. Does anyone know if it breaks down if there are MANY duplicates most of which are 0 or close to 0.

I have attached an example from my data where multiple duplicates appear in the ranking. I am just curious as to why this would happen but in terms of solution I do not want to add a dummy column and I need rankings. Any help would be appreciated. Attached Files Duplicate Rank. That is sort of what I figured. I think I'll be alright with the ranking it is giving since I don't care too much about the 0's and low numbers.

This is showing the rank in ascending order. Can I get it to show in descending order? Example: 1010, 10, 21, 4, 9 the ranking generated will be 3, 2, 3, 1, 6, 5 Ranking is generated twice.

This works fine - unless you have data where the same Area appears more than once in the same group, whereupon it gives all rows the rank of 1. Is there any way to force unique rank values? So two rows that have the same Area would be given the rank of 1 and 2 in an arbitrary order?

Thank you for your time. Assuming you don't have duplicate rows in your table, you can add another column as a tie-breaker in your expression. Suppose your table has an additional column, [Name]that is distinct between your multiple [Area] rows. Then you could write your formula like this:. Learn more. Asked 2 years, 1 month ago.
