Hello All,
I am unable to understand how Anaplan is using data referencing.
Please see the below scenario. I have to create a system module with product SKU details. I am using SKU Flat list as dimension and Code,Products and Distribution Center as Line item. I have imported the data from a CSV file and it looks like this.

The below is the blue print for this module.

As you can see I have used product flat list , and Location flat list as format for these line items (code as text). My question is that how come Anaplan has reference location flat list in my module and generated the exact location names , when the CSV file only had location codes only not the names. Please see the data mapping image below for the .CSV file.

Also see the screenshot of the Location Flat list. there is no Code information loaded in it.
I cannot understand how Anaplan know which code is related to which location name when there is not link between them.

Also I have another question that why do I have to use a formula for the code line item in this scenario when I already have this code information generated through the .csv file please see the first shared screen-short. I am referring from lesson 1.4.3.2 from Sprint 1 Level 2. as it is a part of the activity. see the below image of the activity.
I also don't know how to reference this code formula as I dont have codes in my flat lists.

I will appreciate if someone can provide this information.
thanks
