Hi Satish,
Thank you for your help.
I didn't clearly explain the problem.
There are other purchasing organizations in my company.
They are also using automatic creation of PO and they need NB standard PO to be default.
If I change it in Define Default values for Document Types it will be changed for all purchasing organizations?
Is there a way to define default doc. type of purchase orders for purchasing organization or for movement type?
Thank you and best regards.
