How to create error handling msg inbound proxy in ecc as well as message should then show up as red in SXMB_MONI.

Hi SAP Guru's

My scenario :

Ecc system receiving data from SAP PI ( Service order data) , in Ecc system by using inbound proxy to collect the data and try to creating Service order .

When ever data is insufficient to create service order,i.e creation failed , then error message should trigger, those error msg info should display as red in SXMB_MONI.

Note : I CAN CREATE SERVICE ORDER BY USING INPUT DATA ( WORKING FINE), BUT WHEN SERVICE ORDER NOT CREATED ,ERROR MESSAGE SHOULD TRIGGER AND DISPLAY AS RED IN SXMB_MONI..

WHAT LOGIC NEED TO IMPLEMENT HERE.

KINDLY HELP OUT THIS PROBLEM .

THANKS IN ADVANCE.
