Yes.. you can import the PO with approved status and project using PDOI (Purchase Document Open Interface).
Following 3 interface tables are used to import the PO.
You have to populate the project id to import the po with project no.
Thanks for your reply, actually we want to skip the approval workflow because of huge data and wants to import it using projects details (project id , task id,...)
can it be done by skipping approval workflow for PO or is there any API to skip the approval workflow process.
I think this is not possible because importing PO with approval status must pass thru the process of validations and user defined rules.
