Question { Accenture, 16466 }

Diff B/W
MAP Parameter,
SESSION Paramater,
DataBase connection session parameters.?

Its possible to Create 3parameters at a time?

If Possible which one will fire FIRST?

Answer

upto my knowledge, performance wise mapping parameter is
best to use, but according to requirement you can override
the mapping parameters by workflow variable(to know more
about this you can just check the workflow properties) and
session parameters are just database connections....
correct me if i am wrong.
