Any standard API to insert new Lines/Dists to Existing Purchase Order/Purchase Requisition Headers

Hi,

As per my understanding we can make use of seeded interface tables for PO/PR headers/Line/Distributions while trying to create all of them at once. But our requirement is to create the Lines and Distributions to the previously generated PO/PR headers.

We are on Oracle Applications R12.1.3 Version. Users create the Purchase Order (PO)/Purchase Requisition (PR) manually, but requirement is to Create new Lines and Distributions for the PO/PRs. Do we have any Standard API or a way to achieve this requirement?

Thanks
