Status Changes in CHARM

Hi Everyone,

I am currently working with CHARM in solman. I use the transaction 'CRMD_DNO_MONITOR' . Here there are two status system status and user status. The user status is set by the user like in development , to be tested , successfully tested etc., My problem now is i need to find out whether the user status is changed or not ... searching in sdn i got the idea of using the badi 'ORDER_SAVE'. I checked this badi, while debugging this i found out the status is changed (using CRM_ORDER_READ FM). This gives me the current status . But i need to find out whether my status is changed r not .Can anyone suggest me a way to find out whether the status of a particular change document is changed r not .

Thanks & Regards,

Kevin.
