Tables to be used while uploading open sales orders

Could some one help me out in understanding whether “inventtrans” table is required to upload the data of open sales orders in to Dynamics ax.

I tried doing so, by not specifying the “lotID” field in the sales lines. This throws an exception after uploading the open sales orders and doesn’t allow me to make any transactions further

Yes the invent trans needs to be populated, otherwise there is no data behind the line, and you cannot pick, ship or invoice anything. I cannot help beyond that as I would ask a developer to deliver it for me [:D]
