Logging and Handling Microsoft Dynamics CRM 2013 Exceptions – Part 3

July 15, 2014

In the previous post I described a solution to the business problem of logging & handling implementation level exceptions (presented in the first post of this series).
In this post, I will supply an actual solution, demonstrate common usage scenarios and other solution features.

Before I walkthrough usage scenarios, some implementation notes:

In order to support exceptions raised from transactional components (such as Plugin registered to pre/post operation stages), the LogException method in ExceptionManagement.cs file is using the ExecuteMultipleRequest class to execute the e4d_LogExceptionRequest request. As the ExecuteMultipleRequest instance is external to the Plugin transaction, it manages to create the Exception record without the Plugin transaction rolling it back. Using the Execute method directly with the e4d_LogExceptionRequest request instead, would have executed the LogException Action, but the created Exception record would have been deleted by the Plugin transaction rollback, leaving no trace.

The provided Exception Management solution is unmanaged. This allows you to modify the solution freely but note that unmanaged solution can not be uninstalled.

The provided Exception Management solution is exported as MSCRM2013 6.0 compatible.

As an Exception record is created on behalf of a user, all users must have the Create, Read and Write privileges for the Exception entity.
The solution contains a custom Security Role named Exception Logging Authorized which includes these privileges for the Exception entity. Make sure you add this role to your users or add the privilege to their existing roles.

Ok, let’s get some work done:

Step 1: import and configure the Exception Management solution:

1. Download and extract the E4D MSCRM2013 Excreption Management.zip package.
2. Import the solution ExceptionManagement_1_0_0_0_target_CRM_6.0.zip.  Leave the ‘Enable any SDK message…’ checkbox checked.
3. Add the Exception entity to the Settings area.
4. Publish the solution.
5. Add the Exception Logging Authorized Security Role to all users.

Step 2: Follow the relevant scenario below to use the Exception Management functionality from your custom code:

Scenario 1: Logging Exceptions from JavaScript code running in Entity form

1. Open the target entity Form Properties window.
2. In the Events tab, under Form Libraries, add the ExceptionManagement.js library to the form libraries.
3. If the JavaScript Web Resource that contains your custom code does not appear in the form libraries, add it. Make sure it appears below the e4d_ExceptionManagement.js library.


4. In your custom JavaScript code (someFunction in my example), wrap the target code with Try-Catch blocks.
5. In the Catch block, add the following line of code. You can add your own error handling code in the Catch block.

Sdk.logException(error, Sdk.e4d_LogExceptionRequest.PriorityLevel.LOW);

Your code should look similar to this:

function someFunction()
//your custom business logic here
//your custom exception handling here
//log exception. This is the only line of code required in your custom code
//You can set the Priority level to MEDIUM, HIGH or CRITICAL instead of LOW
Sdk.logException(error, Sdk.e4d_LogExceptionRequest.PriorityLevel.LOW);

6. Save and publish the entity form.

Scenario 2: Logging Exceptions from JavaScript code running in HTML Web Resource

1. In your HTML Web Resource, add the following references in that order:

    <script src=”ClientGlobalContext.js.aspx” type=”text/javascript”></script>
<script src=”e4d_exceptionManagement.js” type=”text/javascript”></script>

2. Follow steps 4,5 in the Scenario 1. 3.
3. Save and publish the Web Resource

Scenario 3: Logging Exceptions from c# code running in Plugin/Custom Workflow Activity/.net application

1. Add the ExceptionManagement.cs file to your Visual Studio project
2. In your code, add the following using statement

   using ExceptionMgmtServices;

3. wrap the target code with Try-Catch blocks
4. In the Catch block, add the following line of code. You can add your own error handling code in the Catch block

string friendlyMessage = ExceptionManagement.LogException(ex, service, PriorityLevel.LOW);

Your code should look something like this:

//your custom business logic here
catch (Exception ex)
//your custom exception handling here
//You can set the Priority level to MEDIUM, HIGH, CRITICAL instead of LOW
string friendlyMessage = ExceptionManagement.LogException(ex, service, PriorityLevel.LOW);
//Optionally, throw out the exception to return friendly message to the client
throw new Exception(friendlyMessage);

I advise you test the relevant scenarios by generating an intentional exception, such as calling a non-existing function. Make sure an error message is displayed, an Exception record is created and that the Exception details are correct.

The ExceptionManagement_1_0_0_0_target_CRM_6.0.zip contains a Web Resource named ClientSideExceptionDemo.htm which demonstrate scenario 2.

The E4D MSCRM2013 Excreption Management package contains a sample Plugin project called E4D.CRM.ExceptionMgmtServices.ClientPlugin aimed to demonstrate scenario 3.

Managing Exceptions tools:

Navigate to the Exceptions node in the Settings area to view the Exceptions list. You can feed the unique token displayed in the error message in the Quick Find search box to quickly find the relevant Exception record.
You can export list of Exception records to Excel in order to send out to be reviewed by external developer.




As this solutions is unmanaged, you can can customize and extend it as you wish, here are some ideas:

Create a Workflow Rule that will add exceptions to a designated Queue from which Exceptions can be pulled and handled by developers or system administrators.
Create a Workflow Rule that will send email to administrators group when critical Exception record is created.
Create a Workflow Rule that will send an acknowledgment email to the end user when Exception record is created or handled (status change).
Develop a Custom Workflow Activity or Plugin component that will integrate with your ALM application to automatically send exceptions to be handled by the development team.
Add JavaScript code to display a nice error message using setFormNotification when error is displayed in entity forms, instead of displaying an alert.

I would like to hear your ideas about extending and improving this solution.

    Great post Yaniv. I like the ExecuteMultiple technique to ensure that the exception will always be logged. Neat!
