scenario
SAP -> PI -> MII -> Legacy system folder
PI to MII using webservice
MII to Legacy system folder using FTP
Requirement: Send messages to legacy system from MII in order MII have received from PI system. And Need Message Monitoring which comes with Message services.
Questions:
Which is the better approach using Rule based Message Listener or Category based Message Listener.
Can we use the Message service Actions for Rule based Message Listener and how does it work.
How can we make sure that MII processes the messages in order it has received from PI.
In Rule based message listener does MII buffers the messages received from PI.
Any related document which clearly gives a step by step process for the above.
Appreciate your help.

Hi Srini,
Both types ie categorized and Transaction will work for your cases. MII will process them in the sequence received from PI.
You can use transaction for immediate processing however if you want to refer to these buffered message from MII i future, use category based processing and store the messageid for each,via which you could access them from a transaction via ReadMessage.

Category is a label for the messages being placed in the Message Queue. If you go by the Transaction Processing Rule mode, the incoming messages will be processed by the transaction immediately and not queued up. They should show in the Message Monitor as processed (or failed, etc.)
