How to populate charge account automatically and approval status as Approved in Standard PO using PD

Hi,

I am using purchase order import program to import purchase order from external system, they are importing successfully but I am not able to get authorization status “APPROVED” even I am providing approval status as “APPROVED” and Charge account is not getting populated even I am using charge account id column and providing there with the value of cc id, user need to manually click the distribution then the same charge account is populating when I check its cc id it was the same but why not its getting populated automatically.

Thanks
