Re: how to Buffer data in SAP MII when third party system is down.

Hi Srisailam,

Here you can find more detailed information for the data buffer -

in your case you should select processing type "Asynchronous Processing on Error" and consider reasonable retry interval and maximum retry count (these two depend on your scenario and how long do you expect that system to be unavailable).

Best regards,
