Table Joins

Hello Team,

This would be a basic question..

I am creating views in HANA  and I have question that ....

How we can determine left and right  table in analytic view  and attribute view.

Table are in Analytic view are :

1. 1.Attribute view(MARA- I  have selected few field from MARA for creating attribute view ) 
2. 2.VBAP table 

When I change the Joins in Analytic view I have seen different result .

I just want to know how system is declaring which one is left and right in Analytic view?.
