Hi,
As per me , it says that suppose you have used "table 1" in creating Attribute View1 in HANA
Now you are creating an Analytic View using the Attribute View1 created above
In this case, you can't use "table 1" as Fact table in your Analytic View to join it with Attribute View1 (as attribute View is already using this table) as Self Joins are not available here
