Partner Determiantiaon on Outbound Delivery PO

Hi ,

I have a requiremnt where i want to get more partner function for Outbound delivery of PO . Currently it is confuigured to have Ship to party , I want to have another partner function DA.

I configured the Partner schema to have DA and assigned to doc type NLCC( o/b delivery for PO) . When i create the DN the Partner function DA appears with a valure 0 .How can i default this parnter number .

Does PO of delivery looks for the partner from PO to default it,

Any pointer rgarding this will be quite useful for me.

Thanks for all your help.

Kind Regards,

Sameer
