Custom fields in Custom workflow

By using custom workflow , i will make Auto-numbering in CRM 4.0 .

 

I have created a readonly field on Account entity” new_auto” to hold the “Guid” of

Account. As GUID is always unique , so there is no question about it being duplication. We can use prefix whatever we want.  As one can see AC- (GUID). I will use cutom workflow to obtain the GUID of entity when it is created and then update the entity with the prefix+ GUID.

            IWorkflowContext context = contextService.Context;

 

      ICrmService crmService = context.CreateCrmService();

 

      WhoAmIRequest systemUserRequest = new WhoAmIRequest();

 

      WhoAmIResponse systemUser = (WhoAmIResponse)crmService.Execute(systemUserRequest);

 

      ColumnSet cols = new ColumnSet();

 //Getting the ID of entity which unqiue itself

 

      Guid guidID = new Guid(this.objectID.Value.ToString());

 

          // i am using “AC” before GUID.This field will hold the GUID of account

 

      string Number  = “AC-=” + guidID;

 

      TargetRetrieveAccount target = new TargetRetrieveAccount();

 

      target.EntityId = guidID;

      RetrieveRequest getAccount = new RetrieveRequest();

 

      getAccount.ReturnDynamicEntities = true;

 

      getAccount.Target = target;

 

      getAccount.ColumnSet = new AllColumns();

 

      RetrieveResponse retrieved = (RetrieveResponse)crmService.Execute(getAccount);

 

      DynamicEntity regardingAccount = (DynamicEntity)retrieved.BusinessEntity;

 //i am using custom field to hold the value of “GUID” .

 

      if (regardingAccount.Properties.Contains(“new_auto”))

      {

 

          regardingAccount.Properties["new_auto"] = Number;

 

      }

 

      else

      {

 

          regardingAccount.Properties.Add(new StringProperty(“new_auto”, Number));

      }

 

         crmService.Update(regardingAccount);

 

     

           return ActivityExecutionStatus.Closed;

 

        }

 

 

        public static DependencyProperty objectIDProperty = DependencyProperty.Register(“objectID”, typeof(Lookup), typeof(Activity1));

 

 

 

        [CrmInput(" objectID")]

 

       [CrmReferenceTarget("account")]

 

       // [CrmReferenceTarget("automatic.crm.new_audit")]

       // public.automatic.crm.Lookup

 

        public Lookup  objectID

        {

 

            get

            {

 

                return (Lookup)base.GetValue(objectIDProperty);

 

            }

 

            set

            {

 

                base.SetValue(objectIDProperty, value);

 

            }

        }

 

  }

}

Finally we need to publish the workflow using developer tool and then calling the assembly from workflow.
