SAP Note 28662 - How does the exclusive indicator perform in the access seque

Symptom:

Symptom

The exclusive indicator is not set in the detail screen of the access sequence for message determination. The customer expects now that several messages are found and outputted if condition records are created in several condition tables of the access sequence. However this does not happen. In message determination, only one message is outputted for each output type, unless, the messages have different partners, then several messages can also be created for each message type.
If the exclusive indicator is set, the first message found is outputted and the further evaluation is completed.
If the exclusive indicator is not set, the first message found is not displayed. The system continues searching and finds a further message. The message found last is now outputted. The message found last is taken into account for the respective partner for.messages to different partners. A message is generated for every partner.
The exclusive indicator should always be set in the message determination. If this is not the case, the search order is the opposite in the corresponding access sequence.

Solution
If an output to several output devices is requested (for example fax and printer), a second output type must be configured. To generate a print out of a purchase order, the output type NEU and a further message type NEW1 have to be defined. In Release 2.1 and 2.2, you must take into account for message determination for purchasing that the first output type MUST be called NEW and that further message types must be called NEUXNEU1, NEU2, as otherwise this results in problems with change messages. In Release 3.0 this restriction has been dropped.
The exclusive indicator always has to be set in message determination.
