You can delete process messages and their logs within process management. The following functions are available for this purpose:

• Manual or automatic deletion of all message data within a specified range.
  Using this function, you can delete either:

• Messages with their logs, or
• Only message logs

Using the above functions, you can delete any message independent of its processing status. Unintentional deletion of data relevant to subsequent functions is prevented in the following ways:

• Note that the message data is only deleted within process management and not in the message destinations.

• If a message has been sent to the process message record (destination PI01), the long texts and logs created for the message cannot be deleted. This ensures that they are still available for archiving and evaluations after the message has been deleted even though they are not stored in the message record.

• When defining a range of messages to be deleted, you can exclude all messages which have not yet been sent successfully.

• When you delete messages within the monitor, a warning is issued if one of the selected messages has not yet been sent.
