BRI Rule Problem with Content Based Routing

Question

Hi,

I am using the ESB generic WCF receive port and I am using a "generic" business rule to assign the correct itinerary. I am having a problem writing a business rule that does this:

IF Context Message Type = "some-doc-spec-1"
  AND
    (doc-content = 'X' OR doc-content = 'Y')
OR Context Message Type = "some-doc-spec-2"
OR Context Message Type = "some-doc-spec-3"
THEN
  Set Itinerary Name = zzzz 

Using the above rule, messages of context type "some-doc-spec-1" get selected if they have the correct content, but never for the "OR" conditions. The BRE rule is actually written as:

OR
|_ AND
|    |_   Context Message Type = "some-doc-spec-1" 
|    |_   OR
|           |_ doc-content = 'X'
|           |_ doc-content = 'Y'
|_  Context Message Type = "some-doc-spec-2"
|_  Context Message Type = "some-doc-spec-3"

If I split this rule into 2 rules by putting the outer OR's into another rule:

IF Context Message Type = "some-doc-spec-1"
  AND
    (doc-content = 'X' OR doc-content = 'Y')
THEN
  Set Itinerary Name = zzzz 

plus:

IF  Context Message Type = "some-doc-spec-2"
OR Context Message Type = "some-doc-spec-3"
THEN
  Set Itinerary Name = zzzz 

then itineraries are set for all document types. But this is not ideal - I would rather have one rule per itinerary so I can see all the logic in one place.

Thus it seems you can't have a rule that mixes CONTENT based routing with CONTEXT based routing for different

Does anyone know how to invoke "Test Policy" to test a BRI rule? I believe you need fact creators for the ESB facts, but I don't know where they are.

Hi,Mike

In this rule:
OR
|_ AND
|    |_   Context Message Type = "some-doc-spec-1" 
|    |_   OR
|           |_ doc-content = 'X'
|           |_ doc-content = 'Y'
|_  Context Message Type = "some-doc-spec-2"
|_  Context Message Type = "some-doc-spec-3"

If sub condition AND
                           |_   Context Message Type = "some-doc-spec-1" 
                           |_   OR
                                    |_ doc-content = 'X'
                                    |_ doc-content = 'Y'
Is true, then, rule judgment will finish, action will take place. in other word, the following two conditions will not function if the first sub condition equals True.

Try change the rule to this:
AND
|_ AND
|    |_   Context Message Type = "some-doc-spec-1" 
|    |_   OR
|           |_ doc-content = 'X'
|           |_ doc-content = 'Y'
|_OR
     |_Context Message Type = "some-doc-spec-2"
     |_Context Message Type = "some-doc-spec-3"

Hope it meets your requirement.
Regards
