save sales header while creating Sales order

Hi all,

I have a text and want to save it in sales header text while creating sales order not after creating sales order.

In this case i tried using SAVE_TEXT in the enhancement but text is not getting saved.

I pass object, id ,language and text in the FM. But I dont know what to pass for Name in FM as this is called while creating sales order. We cannot give sales order number as it is not generated.

please let me know how to save the text

Regards

Siva
