How do I update one database field in CRM 4.0 which is NOT on the form using java script

Hello Experts,
the CRM order you can either maintain a Contact or Account into the Customer field. Depending on the type the order is linked either to the contact or account.
The database 'dbo.SalesOrderBase' has two fields for the link:
- AccountID
- ContactID
I would like to use java script to update the 'AccountID' if a Contact is entered into the order Customer field.
Does anybody have an example code on how to update a database field which is not on the form?
Thanks
Holger

Hi WIttenstein,

You can use a CRM workflow to achieve this easily.
In case you still want to use JavaScript you will have to write a lot of code manually.

You can use a helper library from Avanade : http://www.avanadeblog.com/xrm/2010/07/updated-crmservicejs.html to simplify your task but without proper knowledge of CRM and DHTML, it will be really really difficult to do so.
