When you submit a document to the Partner Manager, you can optionally instruct the Partner Manager to log a copy of that document in its message store. The message store is a facility that maintains a document of transactions that the Partner Manager processes. Each transaction document in the message store contains a copy of the document that was submitted to the Partner Manager, along with its routing parameters and an audit trail describing how the document was processed.

You use Integration Server Administrator to view the contents of the message store.

By viewing the message store, you can determine if and when the Partner Manager handled a particular document. You can also determine whether the Partner Manager processed a particular document successfully or returned an error.
