Diagnosis
The incoming message contains a reference to a previous message and mayattempt to refer to values from this message.
However, format module &V1& does not support referencing to previousmessages.
For example, this message contains a reversal for data from a previousmessage.

Procedure
Check whether the message contains components that refer to previousmessages and if so resolve the conflict manually. For example, byreversing data in a reference message. You can only process a messageif the relevant data is available within that message.
