We are trying to create a blackout window for a specific business service or CI. Currently we have created a black maintenance window to say users are allowed to do changes mon-fri between 8am and 5pm which means when creating a blackout the conflict tool kicks in and says no when raising changes.
The issue we have is the change manager would like to create blackouts against a business service or specific CI however when creating a blackout I only get certain options which all appear under the CMDB table.
Ill give 2 examples,
1. We have an application called paint.exe and for the next month we want no changes to be made to just this specific CI. How do we select that in the applies to field?
2. We have a business service call infrastructure which covers seven CI's which we need to put a blackout window on but again in the list above I cant select a business service 'Infrastructure'.
If I am missing a key piece of information please let me know but currently I am stumped at to how this works. As I say I've managed to now get the conflict tool working by creating a maintenance window and then a blackout window but this appears to cover all CI's. I understand this because in the Applies to field I put configuration item (cmdb_ci).
Solved! Go to Solution.

Specific Configuration Item
- Choose the specific class from that choice list of configuration item classes that contains the application.
- Define the CONDITION by selecting NAME (choose field), IS (operation), and "paint" as the value box.
Collection of Configuration Items
- Choose the specific class from that choice list of configuration item classes that contains the application.
- Define the CONDITION by selecting NAME (choose field), IS ONE OF (operation), and select/supply the names in the value box.

DAVE!
You are a genius. Thank you so much.
For anyone else who ever might get stuck on how this entire process works. In order for you to have a blackout window you also need to have a maintenance window set up. It would appear that the conflict tool cant work unless you have both items.

The "planned" implementation of the change is used when checking to see if the change will breach a window.
1. A change scheduled within a blackout window will be identified as a conflict.
2. A planned change scheduled outside of a maintenance window will be identified as a conflict.
You do not need to have both windows identified as they are mutually exclusive.
Additionally, I believe conflict detection will check if the affected configuration item has other changes planned for the same time. ServiceNow will see if the planned start/end of one change overlaps other planned changes for the same item. If so, these changes will also be seen as conflicts.
For example,
CHANGE01 planned start 0900, planned end 1000
CHANGE02 planned start 1400, planned end 1600
CHANGE03 planned start 1530, planned end 1730
Conflict will find CHANGE03 is in conflict with CHANGE02 because of the overlapping duration.
