SAP PI 7.3 (Single Stack - Java) XML Messages Archiving

Hi experts,

Does anyone know the process to retrieve archived XML messages in SAP PI 7.3?

We are planning to set up message archiving using XML DAS and I was wondering what would be the process to retrieve them. The messages will be archived in a 3rd party storage system and we are not considering offline archiving.

Thanks.

Regards,

Ricardo
