Validate field from external system

AST

Hi,
I wonder if it's possible to validate field from outside Navision.
In my application (C#) you create sales order and send it to Navision database. Is there any way to write item no to Sales Line table and then validate this field (use Navision code) to fill other fields automatically :?:

I use Navision 5.01 on Sql server 2005

The Business Logic (NAV code) is not exposed to external systems until NAV 2009.

1) For that use webservices (native in NAV 2009, could be done by external DLL for older versions using NAS)
2) Never write into "live" tables from outside application. Because the business logic is not triggered, you can mess whole system. Use own special tables to write the data into and use NAS and some process which will "transfer" the data into "live" tables with running the business logic.
