When a 210 message is sent for customer read, the 300 message that is returned does not always reference the 210.
The Suppliers Business Reference is not always included in the message.
The 210 process is then left open on the Supplier side.
There is a requirement for this process to be amended so that what is sent by a Supplier references what is sent back by ESBN.
When a 210 read is sent and the read is validated, the 300 back to the supplier should always have the Suppliers BusRef included on it at all times
