LookML - filter measure by the dimension in another view

[enrico_spada-16]

Context:

• View 1: Fact Sales
  • Dimension:
    • Date
  • Measure:
    • Total Sales
• View 2: Dim Calendar
  • Dimension:
    • Date
    • Year

Question:

given the above two views which in Explore are combined via join, how can I define the following Measure in the View (LookML): Total Sales filtered by ‘Dim Calendar’[Year = 2020].

This needs to be a new measure that exists within the View definition.

Thank you,

Enrico
