Error Handling Framework In Siebel
Contents |
designed for handling system and user-defined errors. An example of a system generated error is a failure when sending an email notification. An example of a user-defined error handling framework in oracle error is attempting to submit an order that is not complete.You can use an

exception branch to programmatically handle errors and change the flow depending on when an error is encountered. This technique provides error handling framework in java a granular approach to handling exceptions at each step.In the Process Designer an Error Exception appears as a red connector between two steps. When you click an exception connector, the Properties window displays the

connector's WF Step Branch properties.When an error occurs, the error code and error message are automatically populated in the Error Code and Error Message process properties. An exception allows you to set up a condition using values in these properties.Similar to other cases where conditional logic is used in a workflow process, an exception on a step is evaluated after the step has finished. If you need to evaluate c# error handling framework an exception before executing a step, you must attach the exception to the prior step in the workflow process.Example of Error Exception Handling This topic gives one example of defining error exception handling. You might use this feature differently, depending on your business model.In the example displayed in Figure16, when the Get Organization ID step is unable to get data, the workflow continues to the Lookup Sender by Org step. If Lookup Sender by Org fails, the workflow takes the red Exception branch and sends an email using the Send Lookup Error Email step. Figure16. Example of a Workflow That Uses Exception Branches to Programmatically Handle Exceptions Defining an Error Exception An Error Exception is defined in the Process Designer.To define an Error Exception In Siebel Tools, in the Workflow Processes OBLE, right-click the workflow process for which you must define exception handling, then choose Edit Workflow Process. In the Process Designer, drag then drop an Error Exception connector from the palette to the canvas, attaching one end of the connector to an existing step icon for which you need to trap errors. Some example step types you might need to trap for error conditions include the Business Service step type and th
a type of workflow process that runs if another workflow process reaches an error state. If this calling workflow process reaches an error state, then Siebel CRM stops the

then runs the error workflow process.A sub process can call an error workflow process. An error workflow process cannot contain exception handling in siebel escript a sub process.Using an error workflow process to handle errors In the Workflow Processes list, locate the workflow process that must call the error workflow process. For more information, see Locating a Workflow Process http://docs.oracle.com/cd/B40099_02/books/BPFWorkflow/BPFWorkflow_Design22.html in the Workflow Processes List. In the Workflow Processes list, in the Error Process Name property, choose a workflow process. Siebel CRM uses the workflow process that you define in the Error Process Name property as the error workflow process. If the error workflow process must change the state of the calling workflow process, then you can add an error exception connector to the calling workflow process. An error https://docs.oracle.com/cd/E14004_01/books/BPFWorkflow/design_options21.html workflow process does not return values back to the calling workflow process. Benefits of Using an Error-Workflow Process A universal exception handler is an error workflow process that Siebel CRM can use to handle an error that occurs across multiple steps in a workflow process or across multiple workflow processes. You can use it to reduce clutter in a workflow process diagram. You can reuse a single error workflow process that handles the same error for multiple calling workflow processes.How Siebel CRM Handles Errors This topic describes how Siebel CRM handles errors for a workflow process and for a sub process.How Siebel CRM Handles Errors for a Workflow Process If an error occurs in a workflow process, and if the Error Process Name property for this workflow process: Does not contain a value. This workflow process remains in the In Error state and Siebel CRM returns an error code to the object that called this workflow process. Contains a value. Siebel CRM runs the error workflow process.

solutions. Hence I have been hunting for requirements on web which I can discuss with you guys. During my surfing yesterday I came across a requirement which I would like to share with you. I am sharing it with you not because it has http://siebelunleashed.com/handling-errors-in-escript-case-study-2/ an interesting or complex solution but, to emphasize the fact that there are always several ways http://siebelunleashed.com/siebel-try-catch-finally-and-throw-part-4/ to achieve a things in Siebel and completing the requirement should not be your only goal as doing it in a wrong way can severely hamper the long term life of your application. You should always ask this question to yourself. Is there a better way to do it? Well now not wasting much of your precious time let’s get on with the requirement. error handling Requirement: - On Service Agreement list applet we have a button ‘move to batch' - User can select all contracts, or 1 or more contracts using CTRL button, and move these to his batch for executing renewals. - User should not be able to add same contract twice in renewal batch for this ‘User key’ has been used and if user tries to do this he will get “Record with same values already exists” error Here is the part error handling framework of requirement that forced me to write this post. - In eScript code I want to ignore or suppress this particular error and if this comes it should execute the code for next error. My Thoughts: This is absolute wrong way to do this requirement even if you can do it. What you should be doing is to do write your script in such a way that this error doesn’t come at all and there are several easy ways to ensure this. Here is the approach I would have used to accomplish the requirement Solution: In the Applet server Script write the code to implement following logic (I am not providing the complete code). var isRecord = BC.FirstSelected(); while(isRecord) { Call a workflow and pass the field values that are part of user key isRecord = BC.NextSelected(); } In the Workflow I would query for the record with the values that are passed. If record is found then go to End step otherwise call the Business Service to create a new record or may be use Insert step and avoid all scripting all together. The decision to use Insert Step or BS will depend on how complex the logic is to create the record. If it is simple insertion then pass the values of the required field in the workflow and use it in insert step but if certain kind of data manipulation or validations are
keyword in detail. What is throw? In simple words throw is keyword used in error handling 🙂 Is throw keyword compulsory to use? No, it is optional and in many cases it is not used. What is the purpose of throw? When we write a custom method then we have two choices. First Choice: Handle those errors and take appropriate action in our script. This is accomplished using catch keyword. Second Choice: Let somebody else handle those errors in that case we use throw which in simple language means that "An exception that has occurred I don't know how to handle it so I am passing it to you" (you is Siebel here) and Siebel basically shows a pop-up displaying the description of the error that has occurred. Let's understand this with help of an example
try
{
//some logic to do something
}
catch(e)
{
if(e.toString() == “Say some particular error A”)
{
// do this
}
else
{
throw e;
}
}
finally
{
// make objects null
}
Now according to the above code if error has a some particular description then we handle it otherwise we just pass it on to Siebel which will display it to user. When should we use throw? throw is usually used in business service code which is going to be called from workflow. When an error occurs it will trigger the exception step of a workflow and assign the error information to Error Code and Error Description process properties of workflow. If I don't use throw and just use blank catch try { //some code } catch(e) { ; } then the workflow will not get an exception and it will go on its merry way thinking everything is fine. I hope this clears any doubts that you might have about using throw. In next part I will discuss how to suppress some particular error using catch. << Previous in series Next in series >>Share:PrintEmailTweeteScript eScript← Apply and Activate button in Siebel Toolstry-catch-finally and throw - Final Part → This Post has been viewed : 11,124
