Hi All, I am trying to figure out when to use Sequential Mode. Also, what does SequentailAgenda.SEQUENTIAL and SequentialAgenda.DYNAMIC means. rule "asset > 1000" when s : Security( status == "NOT VALIDATED", country == "USA", asset then s.setStatus("VALIDATED"); end rule "asset < 1000 and no_of_shares > 150000" when s : Security( status == "NOT VALIDATED", country == "USA", asset < 1000, no_of_share > 150000) then s.setStatus("VALIDATED"); end There are 50 more such rules. 90000 such Security objects will be inserted in WM as facts and the rules applied. The moment a Security becomes VALIDATED all other Activations on the same fact should be cancelled. Is this example a candidate for Sequential Mode. What difference will it make if I put the set the SequentialAgenda to SEQUENTIAL or DYNAMIC. Thanks.
