Data Model with comma separated list
Hey all, I'm currently struggling to create a nice data model out of a single table that contains about 6 columns that contain comma separated lists. A small example:
| Recipe ID | Ingredients | Country |
| 1 | eggs,milk,flour | Netherlands, United Kingdom |
| 2 | eggs,aubergine,parmezan | Italy, Spain, France |
| 3 | parmezan,basil,tomato | Italy, Croatia, Austria |
So I want to create a nice data model out of something like this (actual table has 20+ columns, with 6+ containing comma separated lists).
So I felt my central table (is it technically a Fct table?) should contain the recipe ID. The problem is with the dimensions. Let's say I want to be able to filter for all recipes containing eggs, and all recipes with country:italy. This means I should have dimensions for County and Ingredients. Those dimensions need to be related to the fctRecipe, but... how? My solution so far is to create a relation between the comma separated column and the comma separated column in the "countries" and "ingredients" dimension, like so:
Where the "countries" column contains values like "italy,croatia,austria" and the country column contains "italy", "croatia" etc. Is this the best way of doing it, or am I overlooking an option?
My first instinct would be to just split the comma separated lists into rows, but that doesnt work very well when you have multiple comma separated lists in your table. You would end up with a cathesian product of all combinations of countries and ingredients in this case 😞
Thanks for thinking along!

Anonymous , Not very clear. but you can split the the column using https://www.tutorialgateway.org/how-to-split-columns-in-power-bi/
Hi Anonymous ,
What kind of model to create and how to create it is more appropriate depends on what function you ultimately want to achieve. Please provide your desired result and the calculation logic if it is involved.
In addition, I created a sample pbix file(see attachment) for you. Please check whether that is what you want.

Split the Column to Rows with Comma Delimeter and Replace Values " (Double quotes) with "" (null) then your problem would be sorted out!
