Fulfilling location on the sales movement of POSDM

Hi All,

We have a requirement where we need to populate the stock fulfilling location on the POSDM, Billing document and article document.

on our Ecommerce business when an item is purchased by the customer, this item can be shipped to customer by our different fulfilling locations like Warehouses, Nearest Store of the customer etc.,

above transaction doesn't get posted to SAP until the items were shipped to the customer.

We are looking for a place holder on the POSDM Sales Movement to capture the fulfilling location information which can be passed to ERP on billing documents and article documents, so that we can report on sales that were fulfilled by perticular location.

on billing document we are planning to use Shipping point / Usage field to capture the fulfulling locations.

We are yet to confirm on the field on Article document.

Please advise on POSDM which filed can be used to populate the fulfilling site number.

any help is greatly appreciated.

Thanks

Shreya.
