New/Change Indicator for Sales Order IDoc

Hi Gurus,

Does anyone knows if there's a field in the IDoc Segment for ORDERS that shows or indicate if it's a new or changed order.

We are sending IDocs to our freight company for sales order, but we are trying to see if there's a way we can let them know if its a new or changed IDoc for sales order.

Is there any field for this or any work around on this?

Thanks for your help.
