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