Dear Krishna,
each MSMP process id has a global rule for notification (see step 2 in MSMP configuration). SAP standard rule is GRAC_NOTIF_VAR_RULE_AR.
Within this function module you are able to change the notifications. For any modification it's recommended to copy the standard rule to a Z* rule and assign the rule to your MSMP process.
Please do let us know if you need further input.
Best regards,
Alessandro
