Can't update Order ID from an SSIS package

Hi all,

I am developing an SSIS package for integration between CRM 2013 and Axapta.

When an Order is created in CRM, it is given an Order ID automatically, then it is exported to Axapta,

and I fetch the newly created Order in Axapta, to update the Order ID of the CRM Order.

However the Order ID is not updated for some reason, even though all the other fields that I fetch from Axapta, are updated.

What could be the reason for this to occur?

Here is the code that I use to update the Order ID, if it could be of any help:

if (!Row.SALESID_IsNull)
{
salesOrder["ordernumber"] = Row.SALESID.ToString();
}

...

_orgService.Update(salesOrder);

Thanks.

Best regards,

Evgeni Dyulgerov
