How To Fix V6550 - Reference to one location is not identified uniquely

SAP Error Message - Details

• Message type: E = Error

• Message class: V6 - Interface to External Transportation Systems

• Message number: 550

• Message text: Reference to one location is not identified uniquely

What causes this issue?

The reference of the transportation connection point to a different
location (customer, shipping point, etc.) has not been defined
uniquely. This happens, for example, when you specify both a customer
number and a shipping point number or both a reference and an address
for a transportation connection point. The system cannot process the
resulting ambiguity.

System Response

You cannot continue processing with this data.

How to fix this error?

Correct the reference data such that there is a unique reference:
Customer and unloading point
or vendor
or shipping point and loading point
or plant and storage location
or address
In addition to the shipping point or plant, you can specify a
combination of storage location number and gate.
If an address has been defined together with the reference, delete
either the reference or the address.
