thanks for your reply.
the last question is:
when I am creating agent rule in brf+, in condition column of the decision table, I selected REQ NO. and BUSINESS PROCESS
and in RESULT COLUMN, I selected only USER ID, but when I am trying activate it I giving error.
and when I select all the objects of result data: USER ID, LINE ITEM, RECIPIENT and TYPE,
it is successfully activated.
so my question is:
is all these 4 objects (user id, line item, recipient and type) are mandatory in AGENT RESULT DATA?
