If a customer has a Same Entity relationship with a shipping location, then it cannot have a Same Entity relationship with another shipping location. The converse is also true; if a shipping location has a Same Entity relationship with a Customer, it cannot have a Same Entity relationship with a different customer. The only exception is that a customer can have a Same Entity relationship with both a load-at and a consignee.
A Same Entity relationship must exist for Shipping Locations referenced by Responsible Customer Overrides. This will allow the corresponding Customer ID to be assigned to Secondary Vouchers generated during A/R Voucher Generation.
