How to Combine Data from Multiple Columns in DAX - For use in a Slicer

[jjck]

I am trying to create a slicer that can select which increase in percentage (or just the base value) is represented in all visuals/cards for a single page. They need to be categorized by Order ID in order for me to filter by other field (such as business sector, date of order, etc.). 

I know how to do this in Excel, but I want the page to be replicable by someone else once I transfer out of the department, so having a DAX code they could copy and paste when they refresh the dashboard is really what I'm after here. 

An example of the data I currently am working with is below:

Order ID	Base Value	2%	3%	5%
1	100	102	103	105
2	300	306	309	315
3	150	153	154.5	157.5
4	200	204	206	210

Any advice would be extremely helpful, and deeply appreciated. 

Thanks in advance, 

jjck

Hi, @jjck 

Pick ID and Base value in PowerQuery, then select Unpivot Other Columns.

Select Apply. Then create a new column, use the following dax:

CombinedColumn = COMBINEVALUES ( "|", 'Table'[Order ID], 'Table'[Attribute] )

I am not a Power BI expert, but my gut tells me you are going about this the wrong way using a bunch of calculated columns. In my opinion, a more robust solution would be to create a separate table with the various percentage increases. You can load this easily into a slicer and then create measures for your visuals using SELECTEDVALUE. This also offers the added benefit of adding more increases easily (e.g. 2.5%, 7%, etc.) versus having to expand out the number of calculated columns in your Orders table. My 2 cents.
