Archive synchronous messages

Hello Experts,

As successfully processed synchronous messages cannot be archived in PI and I have gone through the various documents and threads(mentioned below) in SDN which also confirm this point.

XI: synchronous messages can be archived?

Can synchronous messages (EO) be archived in XI?

But if the requirement is to archive the successfully processed synchronous messages,what can be the other possible ways and what are the points needs to be considered for performance.Kindly suggest me the best and easy way of doing this.

Also ,as we can persist synchronous error and without error messages awaiting deletion for some time by specifying RETENTION PERIOD using SXMB_ADM but what should be the appropriate values for this retention period keeping performance in view and how can we decide these values.My scenario is RFC-SOAP.

Kind Regards,

Kubra.
