** Use of 3 values in 'Receiver From' property of the BPM send step

Hi Friends,

Still I am not clear the exact use of 'Receiver From' property of the Send step in BPM. This property is having 3 possible values: 'Send Context', 'Receivers List', & 'Response to Message'.

What's the purpose of each value ? In what situations, which value we have to use.

Kindly clarify friends.

Kind Regards,

Jeg P.
