Hi Friends,

I have a requirement to create a plugin.

In a opportunity Entity there is a out of box Field "Success" of option type Having items(10%, 20%,30%).

Req- When a user changes e.g. 10% to 20% I want to capture 10% and then i will do calculation a and store its value in a another field.

So on which event (prevalidation , preoperation or post operation) I should register the plugin ?

Thanks

Hello,

If the field, in which you want to store the calculation result, is in the same entity then PreOperation

This saves some internal latency because you don't have to update any other records and it also prevents you from accidentally updating the same record multiple times.

If you want to store the calculation result in another entity, then PostOperation

Because you want to make sure the commit to the database has finished, so you can continue with your action in a separate transaction

Check out this article on the differences between the different pipeline stages:
https://docs.microsoft.com/en-us/dynamics365/customer-engagement/developer/event-execution-pipeline

Hope this helps you get started. If you have any other questions, please let me know!

For your scenario you should register it on Create and on Update, so your plug-in triggers when a new record is created and when one is updated.

Make sure that for Update you only trigger you plug-in when the 'Success' field has been changed, to avoid unnecessary execution of your code.

Hi Michel,

I am getting error I am using following code.

I registered it in preoperation event

Message - update

Filter attribute - success

So when ever success option set change i want to do some calculation by taking its previous value.

Means it if it 10% and user change 10% to 20% then i want to fetch 10% and then i will do some calculation

and then i will update a another field.

Kindly suggest

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.Text.RegularExpressions;

using Microsoft.Xrm.Sdk;

using System.ServiceModel;

namespace PreopAgingChanceofSuccess

{

public classSuccess :IPlugin

{

public void Execute(IServiceProvider serviceProvider)

{

//Extract the tracing service for use in debugging sandboxed plug-ins.

ITracingService tracingService = (ITracingService)serviceProvider.GetService(typeof(ITracingService));

IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));

tracingService.Trace("Plugin enetering in update");

try

{

int statusCode = 0;

if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)

{

if (context.Depth > 1) { return; }

//obtain the target entity from input parameters

Entity entity = (Entity)context.InputParameters["Target"];

if (entity.Attributes.Contains("kkk_chanceofsuccess")) // getting error in this line

{

string optionsetScuccess = entity.FormattedValues["kkk_chanceofsuccess"].ToString();

optionsetChanceofScuccess = Regex.Replace(optionsetChanceofScuccess, "[^0-9]+", string.Empty);

throw new InvalidPluginExecutionException(optionsetScuccess);

}

}

}

catch (FaultException<OrganizationServiceFault> ex)

{

throw new InvalidPluginExecutionException(ex.Message.ToString());

}

catch (Exception ex)

{

tracingService.Trace(ex.ToString());

throw;

}

}

}

}

error -

Unexpected exception from plug-in (Execute): PreopSuccess.PreOperationSuccess: System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary. If you contact support, please provide the technical details.

As you mentioned in filter attribute you have put - success , you should put name of the attribute not value of the attribute.

I can see your attribute name is kkk_chanceofsuccess so you need to put kkk_chanceofsuccess in the filtering attribute instead plugin registration tool instead of success.

Hope this helps.

Hi,

I don't think the error is thrown on the line if (entity.Attributes.Contains("kkk_chanceofsuccess")) as here we are just checking if it exists or not. The error "key not found" means the key we are using in the collection doesn't exists in the collection and we are using the key is just this statement "entity.FormattedValues["kkk_chanceofsuccess"].ToString();" which could throw "key not found" exception.

It appears that you are trying to get the text value of your option set. If that's true then you can try the below link to retrieve the metadata.

community.dynamics.com/.../retrieve-option-set-metadata-in-c

You can also hardoce the the values insyead of retrieving the text value i.e.

if(value == 10000000)

{

text = 10;

}

else if(value == 10000001)

{

text = 20;

}

else

{

text = 30;

}

Hope this helps.
