Program to re-schedule process chains

Hi All,

Could you please help me in knowing if there is any program for re-scheduling process chains.

In our project we have several process chains to be re-scheduled during the time of outage/maintainance.

Example: Suppose we have have a process chain XXX1 with start date 12.09.2014 and start time 15:00. Via program if I give the process chain name

and re-schedule date at 13.09.2014, then the process chain should be scheduled to 13.09.2014.

Please help me in this. It will reduce the manual work.

Thanks In Advance!!

Regards,
