Creating Job in SDK

Hello,

I'm trying to add a Sales Invoice to our system. Unfortunately, I cannot see that it is possible to create a new Job record and have it added to Peachtree. It seems it would be as simple as  m_job = m_sessionInfo.CompanyContext.Factories.JobFactory.Create(); However, that function doesn't exist. Furthermore it seems that the Job Entity only has read only properties.

Is it possible that the Job Entity is read-only? Is there any work around?

 m_salesInvoice = m_sessionInfo.CompanyContext.Factories.SalesInvoiceFactory.Create();
