Blanket Order to Sales Order conversion and Invoicing Problm

Hi Experts!

I'm using NAV 2009.

After making all the necessary configuration, now, I'm converting a Blanket Order to Sales Order.
Each entry in the list is converted into a separate Sales Order(as I enter the 'Quantity to Ship' Column for only one entry).

The Sales Order(like the Blanket Order) consists of multiple list entries.

When i try converting this Sales Order into an Invoice by specifying the Quantity to Ship for only one list entry(out of all the entries in the list), i get a consistancy error as the rest of the entries are present and thier corresponding 'Quantity to Ship' column is empty. I have to delete the unwanted entries everytime im posting an Order havin multiple list entries. Is there a way around this?

Doing this is quite tidious and it would be great if there's a simpler way to do this.

Kindly give me a solution for this difficulty.

Thanks!

Regards,

Richard
