1. What happens when both reject flags are activated (inner join reject & output reject)?
2. If there is more than one output and more than one expression filter, lets say there are two ouputs and two expression filters, one for each output, (in the output of the tMap), how does the output choose which expression filter rejects to take?
You can pull two link for output to know which join fails .In first link you do only inner join reject(i.e if the value will present in table A and it will not present in countries table then it will go in reject.) and in second link you do only catch output reject (i.e it will based on your condition means it will catch the records rejected by a filter you have defined in the appropriate area).
