Isah origin
This value depends on the identification method of your own company (@schemeID) as set on the Supply Chain tab of PurchaseDocument.VendId in T_Vendor.
Note: If the registration of your own company (Customer '99999') has an InvCustId that differs from CustId, the Party identifier will be taken from InvCustId. The @schemeID will not be affected; this is always taken from the Supply Chain tab in T_Customer.
