Hi @Revanth Karra thank you for the reply. 

I recieved the following error: JavaScript parse error at line (1) column (54) problem = missing ; before statement (<refname>; line 1)

the condition written was:
BLACKOUT_START_DATE <= current.planned_start_date AND current.planned_start_date <= BLACKOUT_END_DATE;

can you help me with the condition error?

black out start date and black out end date, both of the fields are not available in change request table, please help from where i need to get them

Blackout schedules are stored in the 'cmn_schedule_blackout' table.

The OP hear can view the client script named 'Conflict change' which checks planned_start_date and planned_end_date against the blackout schedules on the change_request record. Create a similar client script, runs onSubmit that has:

        //Abort the submission
        return false;

to abort the submission.

There is the "Change Management - Collision Detector" plugin that can work here.
