I am new to plugins. I need to create a plugin that does the following on contact entity:
Retrieve value from custom_field_A
Retrieve value from custom_field_B
Retrieve value from custom_field_C
Do some mathematical calculations with the fieldvalues
Put the result into custom_field_D
Can anyone help me with this code? I am guessing it's quite simple, but being new to this, it would be nice to get some starting help.

Your plugin can't cause that exception based on the code you posted.
But your code will work properly only in "Create" scenario. For Update Scenario - it will use only previous values (what if field was changed - you have to take it from Target and not from Image) also to put it again - use Target, not Image.
Good luck.
I know about calculated fields. The problem is that we have reached our limit of 10 and cannot create anymore fields of this type. Another thing is that the calculation we are going to do in the future, seems more complex than calculated fields can handle.
Here is the code:
using Microsoft.Xrm.Sdk;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ContactCalculator
{
public class ContactCalculatorPlugin : IPlugin
{
public void Execute(IServiceProvider serviceProvider)
{
// Extract the tracing service for use in debugging sandboxed plug-ins.
ITracingService tracingService =
(ITracingService)serviceProvider.GetService(typeof(ITracingService));
// Obtain the execution context from the service provider.
IPluginExecutionContext context = (IPluginExecutionContext)
serviceProvider.GetService(typeof(IPluginExecutionContext));
// Obtain the organization service reference.
IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);
if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)
{
// Obtain the target entity from the input parameters.
Entity contact = (Entity)context.InputParameters["Target"];
Entity contactimage = context.PreEntityImages["Target"];
string ourdescription = string.Empty;
string total = string.Empty;
string custom_field_A = string.Empty;
string custom_field_B = string.Empty;
string custom_field_C = string.Empty;
string custom_field_D = string.Empty;
if (context.MessageName.ToUpper() == "CREATE")
{
if (contact.Attributes.Contains("custom_field_A"))
{
custom_field_A = contact["custom_field_A"].ToString();
}
if (contact.Attributes.Contains("custom_field_B"))
{
custom_field_B = contact["custom_field_B"].ToString();
}
if (contact.Attributes.Contains("custom_field_C"))
{
custom_field_C = contact["custom_field_C"].ToString();
}
// Do ur calculation as per ur requirement and store it in custom_field_D variable
custom_field_D = custom_field_A + custom_field_B + custom_field_C;
contact["custom_field_D"] = custom_field_D;
}
if (context.MessageName.ToUpper() == "UPDATE")
{
if (contactimage.Attributes.Contains("crmn_ourcandidaterating"))
{
ourdescription = contactimage["crmn_ourcandidaterating"].ToString();
}
if (contactimage.Attributes.Contains("custom_field_A"))
{
custom_field_A = contactimage["custom_field_A"].ToString();
}
if (contactimage.Attributes.Contains("custom_field_B"))
{
custom_field_B = contactimage["custom_field_B"].ToString();
}
if (contactimage.Attributes.Contains("custom_field_C"))
{
custom_field_C = contactimage["custom_field_C"].ToString();
}
// Do ur calculation as per ur requirement and store it in custom_field_D variable
total = ourdescription;
contactimage["description"] = "testing 123";
}
// Write this plugin on Pre-Operations Stage to avoid one additional transaction to update the value in DB
// can write this plugin on Create as well as on Update
// Can avoid below line by reg plug-in in Pre Operation Stage
// Service.update(contact);
}
}
}
}
Hi,
If all this custom fields are in contact entity only & field type is number then you don’t need plugin
What you can do is create new custom field as calculated field type & do all your mathematical calculations of field a,b & c
So as a result whenever user changes any field of a,b & c your cacluted field will be auto updated with desired result
Hope it will solve your problem & remember to mark this as answer
Thank you. One step closer. The plugin launches now, but it fails. When I look at the systemjob in Dynamics it gives us this message:
The token provider was unable to provide a security token while accessing 'losangmdm-sb.accesscontrol.windows.net/.../&;. Token provider returned message: 'Error:Code:401:SubCode:T0:Detail:ACS50008: SAML token is invalid.:TraceID:4298b45f-8c1a-473a-9fb1-d297b61bbf5d:TimeStamp:2017-12-01 15:22:57Z'.
Any ideas what this might be?
