I am a beginner in Anaplan, just finished my training course and started building my first model. What I am trying to achieve here is to sum a column (input) based on each record's category (another input, formatted as list created previously).
For instance, This is my input:
Note that I have created a list called category, and there are three items in that list (A B C).
I put the category in the page dimension so I can toggle. I did not have a line item called category.
What I would like to achieve is to add a total value column to show the total column of that category when I toggle that category.
How can I achieve this? I tried Value[sum:Category] but it says it is not a line item. Should i create a property in the category list so i can use it in the formula?
you are correct this is the classic SUM usage. You probably did a slight mistake. here's how it should be:
Your "Data" source module should have two line items: Value and Category and a "transaction" dimension (1,2,3,4, etc) to make the rows. it seems you have this already.
Now in your target module you can have a line item called "SUM" and the category list as a dimension. The formula of this line item should be: Data.Value[SUM:Data.category]
This will give you the sum of the category you select
This is essentially what you have done so just be careful to what you write as the SUM parameter: it must be a line item in a source module, not a list name, formatted as the dimension you want to SUM on in your target module.
