Restarting Error Message

Hi all,

I am reading this blog /people/sap.user72/blog/2005/11/29/xi-how-to-re-process-failed-xi-messages-automatically and trying out the restarting of error messages.

I have purposely created a message mapping error. However, when i look in sxmb_moni, the message did not restart after the error.

In the blog it mentions that

IS_Retry A batch job( internal in XI) is automatically scheduled to reprocess the entry after 2 minutes.

Is there any settings that i am missing out?
