Selling Goods To Subsidiary scenario SAP Business Bydesign

Hi all,

I'm facing some issues related to the standard purchasing integration between SAP ECC and SAP BYD using PI as integration layer.

Does anyone have some integration guides (not the guides available on wiki SAP because I have these ones) that explain more in details how I can manage the integration? Do you have any guide for the mapping that we need to implement in PI for the standard flows (Purchase order, PO confirmation, ASN, Supplier invoice).

Thank you so much
