Process Message Creation 
Use
Process messages are created by process control to report actual data on the execution of a process order. Depending on the event to which it refers, a process message can be created in either of the following ways:
Automatically in the corresponding PI sheet or process control system
Automatically in Transaction CO69 – Create Process Messages Automatically
Manually in Transaction CO57 – Create Process Messages Manually
Prerequisites
In all cases, the structure of the process messages must correspond to the predefined message category in Customizing of the SAP system.
Note
You can create test messages to check the definition of your message categories and process instructions.
Within the SAP system, test messages are created and monitored in the same way as productive messages. However, they are neither sent to their destinations nor checked for destination errors.
Messages that are created automatically are marked as test messages provided that the corresponding control recipe has been created for test purposes.
Features
Automatic Creation in Transaction CO69
You can use this transaction to specify that process messages are created automatically according to the following criteria:
In certain time intervals
When a manufacturing event occurs
In this way, you can make sure, for example, that process messages on an event are created even if the relevant PI sheet is not being maintained.
For more information see Creating Process Messages Automatically .
Automatic Creation from PI Sheet or Process Control System
If a process event is planned or expected, the corresponding message can be requested in a process instruction. In this case, the process operator maintaining the PI sheet or the control system processing the control recipe has to provide the process data to be reported in the message. The message of the requested message category is created automatically.
For more information about process data reporting in the PI sheet, see Recording of Actual Process Data .
Manual Creation
You create process messages manually:
In unexpected situations that could not be taken into account in the control recipe (for example, in the case of malfunctions)
If the process control system cannot provide the required information
