Durghamadab - I mean that a table cannot be identified as the right table on a join more than once. Basically a table can be a "right table" only once. But a table can be a "left table" many times. If you click on the join and look at properties you'll see left element and right element.
So basically, Table A cannot have a multiple joins coming in (this will make table A right table). It used to give error before at the calculation level but it's not anymore.
Nidhi - I don't have documentation but was getting an before, but now I'm now. I actually want to see documentation myself.
Siddharth - That scenario makes sense. But I'm concerned within Attribute View only. Can a table be a right table more than once? (it is receiving a join from many sources).
