He first started working on Analysis Services in 1998, back when Analysis Services was known as OLAP Services. So, its just basically from the beginning of time along with the Total Sales. If so you would need to write something like, When you create a variable and assign a table value to it, like JointTable, you cannot follow the naming convention used with physical tables and subsequently refer to columns of the variable table as, If the column originated from a physical table without any renaming, which generally means linage is maintained, you can refer to it by its original fully qualified column name, In your example, I am guessing that SeatNum column comes from the SeatNumbers table.

VAR _t = ADDCOLUMNS (SUMMARIZE . Also, in a row context, you can refer to the values of columns in the current row with a "naked" column reference, such as SeatBookings[Seat Start]. DAX intellisense will even offer the suggestion. Well, in reality, all data is so similar. When you create a variable and assign a table value to it, like JointTable, you cannot follow the naming convention used with physical tables and subsequently refer to columns of the variable table as . This is how we classify our top customers using all these factors. For example, if TableA has rA rows and cA columns, and TableB has rB rows and cB columns, and TableC has rC . For example, you can specify a particular relationship to be used in a calculation. The best way to explain the concept that I want to discuss in this tutorial is through some examples using this simple model. SELECTCOLUMNS has the same signature as ADDCOLUMNS, and has the same behavior except that instead of starting with the
