How To Fix RDM_OPT_OUTBOUND501 - Not every message sent receives an acknowledgement

RDM_OPT_OUTBOUND501 - Overview

• Message type: E = Error

• Message class: RDM_OPT_OUTBOUND - Price Optimization: Messages for Outbound Interfaces

• Message number: 501

• Message text: Not every message sent receives an acknowledgement

What causes this issue?

For all sent messages, the system has requested confirmation of
successful receipt by the recipient. For at least one of the messages,
no confirmation has yet been received. This is not necessarily an error.
In most cases the reason for the missing confirmation is that the
message has not yet been processed completely (for example, because
other messages have been processed with higher priority).

System Response

The data processing is continued.

How to fix this error?

Check later to see if an acknowledgement has been received for all sent
messages. However, the application log for the sent Demand Management
messages is not subsequently updated. Therefore, to check the message
status, you should in each case branch from the application log to the
monitor of processed XML messages. If the message still does not have
the acknowledgement status "Acknowledgement contains no errors", you
should inform the system administrator.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
