OSB Invoking ILOG or External Rules Engine

Hello,
Can OSB invoke ILOG or any external Rules engine ?
Can ALSB do the same ?
If OSB cannot directly invoke, do we need the support of BPEL which has the decision service and OSB invoke the decision service. Kindly help.
Thanks

Yes, both OSB and ALSB can invoke JRules, it's just another web service...

Error when invoking Rule Engine using Java API

Hi,
I have implemented a Java class which calls the Rule Engine to execute the rules. If I test by setting the value of the input inside a main method and get the output, it is working fine. The ruleset is also invoked and there is no problem. However, when I expose this java class as a web service and invoke the web service, I get the below error. I dont get the error if the .rules file is not present in the loaction mentioned. I get the error when the .rules file is present in the location. Not sure if this is an issue with the java call outs or loading the dictionary.

To invoke bussiness rules engine from ADF

hi all,
To invoke the business rule engine running on the SOA server, from the application module. can you please any one help me in this.

Murali,
If the business rules are deployed to the SOA Suite as service-enabled rules, they are just web service calls, correct? You can create a web service proxy class in JDeveloper and then just invoke that class from your AM's java code. There's nothing special with respect to an AM in this case, so if you have detailed questions - probably best to ask in the SOA Suite forum - but no need to complicate the issue by bringing an AM into your question - you just want to invoke a business rule from Java.

Rules Engine Environment in MDM

Hi Everyone,
I am evaluating the capability of SAP MDM to see if there is any kind of rules engine delivered that can create a material master (SKU) number. I am not trying to create material master records yet - just the material number !
Background:
Defned rules, coupled with reference data should be able to generated the list of SKUs.
Example:
Reference Data contained in 3 tables:
Product Line: LN1, LN2
Release: 2009
Language: EN, JA, FR, DE
SKU mask: AA-BB-CC
AA = Product Line
BB = Release
CC = Language
The rules would be to create combinations of all the reference data values and output a list of SKUs according to the SKU mask/format. In other words, by implmenting rules, I should be able to generate 2x1x4 = 8 SKUs in total (2 values for product line, mulitplied by 1 value for Release, multiplied by 4 values for Language).
Questions:
I know I can implment rules on the ABAP workbench in R/3 to create material master numbers, and then later create actual material master records with reference to other materials all within R/3. However, I would like to create and manage the material master directly in MDM.
1) Is a rules engine like drools provided as part of MDM?
2) Since MDM is based on the Netweaver and sits on the web apps server, is there an ABAP workbench provided in MDM from where I can create the rules and create z tables for the reference data.
3) Do I need to create a separate web service in Netweaver Developer Studio to create these rules.
Thanks in advance
-Rajiv

Hi Rajiv,
In some scenarios Material master is imported to SAP MDM from R/3 and all the logic is performed in R/3 itself. For such cases You can use the standrad MDM Material Repository provided by SAP.
<i>How do people create specific part numbers (material numbers / SKUs) in SAP MDM based upon some specific business logic?</i>
Let us say the Part number is an depandant on another field say Product ID.
In MDM Console you can specify the business logic in the Calculation field.
Also i would like to add that in SAP MDM most of this business logic are mere mathematical fuctions (part no = 1.5 * product ID). There is no provision to call external methods (like RFCs in R/3).
I suggest you to get the Standard MDM Materials Repository and play around the Calculated fields\ Auto ID Fields in MDM Console.
Get back for help,
Vijay

Haley Rules Engine - HaleyAuthority with respect to Oracle E Business Suite

I am currently exploring on Haley Rules Engine which is recently aquired by Oracle.
As per my investingation, i came to know that HaleyAuthority ruleEngine is available as plugin from the recent release of Siebel CRM 8.0 installation and onwards.
Here goes my questions
1) is this haleyAuthority rule engine available as third party tool? If so, How to integrate with Oracle E- Business Suite.
2) Like Siebel 8.0, Is this HaleyAuthority plugged in any latest version of our oracle E- Business Suite?
Please let me know your understanding and information on Haley Rules Engine with respect to Oracle E-Business Suite.
Thanks in Advance.

Praveen ,
May be late for you (but for others looking similar information)
haleyAuthority is different from Haley Determination Services (now Oracle Policy Automation)
OPA (Haley's Determination Services) are available as Web Service which you can invoke from E-Business Suite or Use Fusion Middleware (SOA Suite / BPEL) as layer between OPA and E-Business Suite
For overview of Haley Office Rules or Oracle Policy Automation check

Business Rules Engines?

Hi,
I have experience with embedding "CLIPS" which is a C rules engine as a
Forte Service Object which was easily wrappered using standard Forte
wrapper strategy.
Also, we have a sales rep in ATL who used to work @ ILOG and therefore
competed with Nueron Data, and from various conversations with mutual Forte
/ Rules Engine customers I've learned it would be a complimentary integration.
They all have some C-callable API and so a Forte Service Object would be a
good client to the rules engine api due to our support for multi-threading
when API is thread safe and additional option of replicating for load-bal
when API isn't thread safe. The later concept is analogous to our use of
DBSession object for interface with DBMS client api's.
Be aware, the experiences I hear about with the mentioned rules engines is
that there are not always business analysts truly capable of using the
Rules development interfaces provided by the tools.
So maybe the use of Forte Conductor's dynamic Process automation
capabilities may also be a fit. If you want to discuss how, let me know.

Business rules engine faults..

Can someone please advise on what could cause this issue?
We are using SOA suite 11.1.1.2
1. The rules engine takes an input as usual but doesn't send any output.
2. The BPEL process that invokes the rules sends out a bpelFault instead - (because the rules engine doesn't send anything back)
<bpelFault>
<faultType>
<message>0</message>
</faultType>
<selectionFailure>
<part name="summary" >
<summary>empty variable/expression result. The XPath variable or expression /ns1:callFunctionStatelessDecision/ns1:resultList/ns2:RulesResponse is empty at line 122. An attempt to read or copy data referenced or computed by the XPath expression either had invalid data, according to the XML schema, or did not contain certain optional data. Ensure that the variable or expression result named in the error message is not empty. Enable XML schema validation of related variables to ensure the run-time data is valid. </summary>
</part>
</selectionFailure>
</bpelFault> 3. At other times, the process works fine for the SAME input

Hi Paul:
The short answer is yes. But its not easy.
You will have to add some references to your orchestration:
System.Transactions.DLL, System.Data.DLL, Microsoft.RuleEngine.DLL
Next the BRE will need a connection string to connect to your database.
Create a Variable in the orchestration ex: SQLConn of type System.Data.SqlClient.SqlConnection
Create a Variable in the orchestration ex: RulesConn of type Microsoft.RuleEngine.DataConnection
in an expression shape set the following :
SQLConn = new System.Data.SqlClient.SqlConnection("Initial Catalog=Customer;Data Source=(local);Integrated Security=SSPI;");
RulesConn = new Microsoft.RuleEngine.DataConnection ("database", "tablename", SQLConn);
then call the rules shape.... it should work.
there is a blog post about this I have used in the past:

Rules Engine Question

Hello All,
I am trying to put together a very simple service that uses the Oracle Rules engine, but I can't seem to get anything to happen.
I have set up a class called ScheduleValidity which has three attributes, hour, message, and isValid. The idea is that you pass an instance of this into the rule engine as a fact with the hour set, and then have the rules engine set isValid and the message. When I call the engine however, the object that I am asserting is not being changed. I am sure that I am doing something obviously incorrect, but I can't figure it out.
The RL for the two rules that I have are:
rule checkThatTimeisLateEnough
priority = 0;
if
fact mil.navy.seawarrior.scheduler.ScheduleValidity v0_ScheduleValidity && (
(v0_ScheduleValidity.hour < 9 )))
v0_ScheduleValidity.isValid = false ;
v0_ScheduleValidity.message = "The time is too early" ;
v0_ScheduleValidity.setIsValid(false );
v0_ScheduleValidity.setMessage("Time is too early" );
assert(v0_ScheduleValidity);
} //end rule checkThatTimeisLateEnough;
rule timeIsOk
priority = 0;
if
fact mil.navy.seawarrior.scheduler.ScheduleValidity v0_ScheduleValidity && (
(v0_ScheduleValidity.hour >= 9 )))
v0_ScheduleValidity.isValid = true ;
v0_ScheduleValidity.message = "This time is OK" ;
v0_ScheduleValidity.setIsValid(true );
v0_ScheduleValidity.setMessage("this time is OK" );
} //end rule timeIsOk;
The Web Services code that I am using is:
RuleRepository repository = RepositoryManager.getDefaultRepository("D:\\OC4J10.1.3\\j2ee\\home\\SchedulerRulesTest\\");
String rules = (repository.loadDictionary("SchedulerRulesTest",null)).ruleSetRL("SchedulerRulesTestRS"); //.getRuleSet("SchedulerRulesTestRS").generateRL(null);
String dm = (repository.loadDictionary("SchedulerRulesTest",null)).dataModelRL();
RuleSession rs = new RuleSession();
rs.executeRuleset(rules);
rs.executeRuleset(dm);
Calendar cal = new GregorianCalendar();
cal.setTime(startDateTime);
ScheduleValidity sv = new ScheduleValidity();
sv.setHour(cal.get(Calendar.HOUR_OF_DAY));
sv.setMessage("Default message");
System.out.println("hour:" + sv.getHour());
rs.callFunctionWithArgument("assert",sv);
rs.callFunction("run");
OperationStatus returnOs = new OperationStatus();
returnOs.setMessage(sv.getMessage());
returnOs.setSuccess(sv.isIsValid());
Unfortunately, the sv object's attributes are never being set. Can anyone give me an idea what I am going incorrectly?
Thanks

It isn't required that the ruleset be called main. There are two ways to get your ruleset (as originally named) to be evaluated. The pushRuleset function can be used to push the ruleset onto the ruleset stack or the run function may be invoked with a ruleset name argument. In code either:
rs.callFunctionWithArgument("pushRuleset", "SchedulerRulesTestRS");
rs.callFunction("run");
or
rs.callFunctionWithArgument("run", "SchedulerRulesTestRS");
The first approach is documented in the "Oracle Business Rules Users Guide" in section 2.7.4. For some more info on the ruleset stack, see section 1.4.3 in the "Oracle Business Rules Language Reference".

Rules Engine "anyType" attribute

Hi All,
I have this requirement of dynamically invoking a particular rule, based on the input payload of a bpel process.
In shot, can my rules engine take the payload of anyType and dynamically based on the content will apply the business logic.
Thanks in Advance,

AS 10.1.3.4 and before do not support non-standard JAXB 1.0, e.g., those which require -extension.
There is no workaround.

Business Rule Error: Fact not found in the rule engine working memory, rule

I am trying to create a simple decision table with an input(ValidateInput) and a output(ValidateOutput). The input and output schemas have unbounded and nested elements(Parent-child relationship). When I create a condition(specific condition on input) and in the action I am asserting the output object. But when I run using EM it throws the following exception. It would be helpful if somebody could tell me what could be the problem. Please note when I set the output as ValidateInput object then it runs fine. Also it executes fine with ValidateOutput if it doesn't have unbounded(List) element inside it.
Error Message: {http://xmlns.oracle.com/OracleRules10/OracleRules10_DecisionService_1}operationErroredFault

Non Recoverable Business Fault :
Fact not found in the rule engine working memory, rule session execution failed. The rule session 270013 failed because an instance of the fact com.example.customer.ValidateResponse could not be found in the working memory of the rule session. This is most likely a rule modeling error. The decision service interaction expects the fact instance to exist in the working memory of the rule session. Check the rule actions in rule designer and make sure that a fact of the expected type is being asserted. If the error persists, contact Oracle Support Services. 270013

It's working now..I had to use Global variable to declare child element of the output variable and use the same during action.

Rules Engine using Web Dynpro ABAP

Hi,
Can we build a Rules Engine which works with Web Dynpro-ABAP? Something similar to BRM in CE-7.2.
Thanks,
Prasanna

Do you mean BRM or BRF. BRF is the name of the business rules framework that is integrated in the ABAP engine. BRM is Business Rules Management and a part of NetWeaver CE - running on the Java Stack and a part of SAP NetWeaver BPM (Business Process Management).
Generally if your work is all ABAP based you would use BRF. Here is a small eLearning that shows the usage of BRF within Web Dynpro ABAP.
