Dead Line Monitoring

Dear All,

If I run the IP30 for a specific maint plan range for 1 day interval. After that again if I run the same transaction with 30 days interval for thae same range of maint plans. Then in backround job whether SAP Program will schedule maintenance plan for 1 days interval or for 30 days???

Please clarify...Correct if required..

Regards,

Sundar
