    hi friends,

                  I want to rate the opportunity as cold,warm or hot regarding the value in est.revenue. I've written the following code,

     

    public

     

    void Execute(IServiceProvider

    serviceProvider)

    {

     

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

    ));

     

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

    )

    { 

     

     

    // Obtain the target business entity from the input parmameters.

     

    Entity targetEntity = (Entity)context.InputParameters["Target"

    ];

     

     

    try

    {

     

    decimal rev = (decimal)( targetEntity["estimatedvalue"

    ]);

     

    if

    (rev < 100000)

    targetEntity.Attributes.Add(

    "opportunityratingcode", new OptionSetValue

    (1));

     

    else if

    (rev > 100000 && rev < 200000)

    targetEntity.Attributes.Add(

    "opportunityratingcode", new OptionSetValue

    (2));

     

    else

    targetEntity.Attributes.Add(

    "opportunityratingcode", new OptionSetValue

    (3));

    }

     

     

    catch (Exception

    ex)

    {

     

    throw

    ex;

    }

    }

    }

    

    but its not working properly. The error that I got is 'type casting problem'. Can anyone help me?

    hi,

    it could be because target entity does not have estimatedvalue attribute, i have changed the code little bit to throw an exception if the estimatedvalue doesn't exists in the target entity. also which plugin Message (update, create) you are registered with also the stage. if it is create and then user didn't key in any value on this column then the target entity will have this attribute, if it is update and then the user didn't key in anything, you will have to read from pre image (you need to add image step with your plugin registration step).

    try
            {
                
                IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
                if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)
                {
                    // Obtain the target business entity from the input parmameters.
                    Entity targetEntity = (Entity)context.InputParameters["Target"];
                    if (targetEntity.Attributes.Contains("estimatedvalue"))
                    {
                        decimal rev = targetEntity.GetAttributeValue<decimal>("estimatedvalue");
                        if (rev < 100000)
                            targetEntity.Attributes.Add("opportunityratingcode", new OptionSetValue(1));
                        else if (rev > 100000 && rev < 200000)
                            targetEntity.Attributes.Add("opportunityratingcode", new OptionSetValue(2));
                        else
                            targetEntity.Attributes.Add("opportunityratingcode", new OptionSetValue(3));
                    }
                    else
                        throw new InvalidPluginExecutionException("Target Opportunity entity doesnot have estimatedvalue");
                }
            }
            catch (InvalidPluginExecutionException)
            {
                throw;
            }
            catch (FaultException<Microsoft.Xrm.Sdk.OrganizationServiceFault> ex)
            {
                throw new InvalidPluginExecutionException("An FaultException occurred in the Opportunity plug-in.", ex);
            }
            catch (Exception ex)
            {
                throw new InvalidPluginExecutionException("An Exception occurred in the Opportunity plug-in.", ex);
            }

                {
                    throw new InvalidPluginExecutionException("An Exception occurred in the Opportunity plug-in.", ex);
                }

    hi, change the following line to 

    decimal rev = targetEntity.GetAttributeValue<decimal>("estimatedvalue");

    change to 

    decimal rev = targetEntity.GetAttributeValue<Money>("estimatedvalue").Value;
