A workflow assembly would be a better solution. I create a similar assembly for CRM 4.0 and the code is as under. You will have to change the code for 2011/2013:-
Here is the code. You can use it after changing invoice to salesoreder:-
using System.Collections.Generic;
using System.Text;
using System;
using System.Collections;
using System.Workflow.ComponentModel.Compiler;
using System.Workflow.ComponentModel.Serialization;
using System.Workflow.ComponentModel;
using System.Workflow.ComponentModel.Design;
using System.Workflow.Runtime;
using System.Workflow.Activities;
using System.Workflow.Activities.Rules;
using System.Reflection;
using Microsoft.Crm.Workflow;
using Microsoft.Crm.Sdk;
using Microsoft.Crm.SdkTypeProxy;
using Microsoft.Crm.Sdk.Query;
namespace AutoProductDetail
{
[CrmWorkflowActivity("Invoice Detail Creation")]
public class AutoInvoiceProductDetailWF : Activity
{
protected override ActivityExecutionStatus Execute(ActivityExecutionContext executionContext)
{
IContextService contextService = (IContextService)executionContext.GetService(typeof(IContextService));
IWorkflowContext context = contextService.Context;
ICrmService crmService = context.CreateCrmService();
invoicedetail entity = new invoicedetail();
entity.invoiceid = new Lookup();
entity.invoiceid.Value = invoiceId.Value;
entity.productid = new Lookup();
entity.productid.Value = productid.Value;
entity.quantity = new CrmDecimal();
entity.quantity.Value = quantity.Value;
entity.uomid = new Lookup();
entity.uomid.Value = uomid.Value;
entity.tax = new CrmMoney();
entity.tax.Value = tax.Value;
entity.isproductoverridden = new CrmBoolean();
entity.isproductoverridden.Value = false;
crmService.Create(entity);
return base.Execute(executionContext);
}
public static DependencyProperty invoiceIdProperty =
DependencyProperty.Register("invoiceId",
typeof(Lookup),
typeof(AutoInvoiceProductDetailWF));
[CrmInput("Invoice")]
[CrmReferenceTarget("invoice")]
public Lookup invoiceId
{
get
{
return (Lookup)base.GetValue(invoiceIdProperty);
}
set
{
base.SetValue(invoiceIdProperty, value);
}
}
public static DependencyProperty productidProperty =
DependencyProperty.Register("productid",
typeof(Lookup),
typeof(AutoInvoiceProductDetailWF));
[CrmInput("Product")]
[CrmReferenceTarget("product")]
public Lookup productid
{
get
{
return (Lookup)base.GetValue(productidProperty);
}
set
{
base.SetValue(productidProperty, value);
}
}
public static DependencyProperty uomidProperty =
DependencyProperty.Register("uomid",
typeof(Lookup),
typeof(AutoInvoiceProductDetailWF));
[CrmInput("Unit")]
[CrmReferenceTarget("uom")]
public Lookup uomid
{
get
{
return (Lookup)base.GetValue(uomidProperty);
}
set
{
base.SetValue(uomidProperty, value);
}
}
public static DependencyProperty quantityProperty =
DependencyProperty.Register("quantity",
typeof(CrmDecimal),
typeof(AutoInvoiceProductDetailWF));
[CrmInput("Quantity")]
public CrmDecimal quantity
{
get
{
return (CrmDecimal)base.GetValue(quantityProperty);
}
set
{
base.SetValue(quantityProperty, value);
}
}
public static DependencyProperty taxProperty =
DependencyProperty.Register("tax",
typeof(CrmMoney),
typeof(AutoInvoiceProductDetailWF));
[CrmInput("Tax")]
public CrmMoney tax
{
get
{
return (CrmMoney)base.GetValue(taxProperty);
}
set
{
base.SetValue(taxProperty, value);
}
}
}
}
