Hello Community
I need to create a blackout period that identifies all changes assigned to specific IT teams. If one of these teams attempts to create a Change Request during the blackout period, ServiceNow should notify them of the conflict.
I want to create a Blackout Period using "Change Request" as Source. I have added some conditions such as:
Assigment Group
Company
Model
and so on. I created a Schedyle Entry, everythins is good at this point then I created a Change Request to test my blackout schedule and SN is not detecting the conflict. As per the conflict tab >> Configuration item/Affected CIs, Planned start date and Planned end date are required to run conflict detection <<, for now, I am not able to select a CI in the change form, that's why I need to use "change request" as Source.
I also tried selecting "CI Class" as the source, and then selected "Change Request [change_request]" in the "Applies to" field. That’s the table, isn’t it? The conflict is not being detected by SN.
A CI is required to run the conflict detection script. a CI is mandatory.
Is it possible to create a Blackour period using "Change Request" as "source"? I do not want to select a CI for now.
Can the conflict detection script be adjusted to take the CRs into consideration? This will depend on the conditions or filters in the blackout configuration.

Thank you Sir.
I am confused. The "Change Request" in the Source field should allow me to create a blackout period regardless if a set up a CI in the Change Request Form, then the conflict detection should run whitout issues.
Apologies for many quesntions.

@arturoreyes Yep. Understood..
The blackout and maintenance schedules are ultimately based on the Configuration Item. Regardless of the source you select, the source table must have a link to the CI in order to detect any conflicts.
