Need explanation of time slots shown scheduling assistant for normal change request

Hi there,

 

I recently scheduled a normal change (I only do it a couple times a year).  This time I got a message about a conflict and to use scheduling assistant. ...

 

Can someone explain what exactly determines the time slots shown in scheduling assistant?  For example, if I wanted to schedule my change to end LATER on 10/17 to end at 05:00:00 but the time slots shown cut off at 03:45:00.    I checked the maintenance schedule for the related CI and it basically is from 20:00:00 to 05:00:00 each day.  The maintenance schedule is very close but not exactly matching the what I see in the scheduling assistant.  Again the time slot ends earlier (03:45:00 instead of 05:00:00 like I was expecting.  Also, there's a weird 15 minute gap (see where each slot ends at 23:45:00 each night and then next day slow opens at midnight 00:00:00 (why is that 15 mins not available?).  Basically I was expecting to see slots from 20:00:00 to 05:00:00 each day...   See two screenshots below.

Please let me know what I should check or change to get the time slots available aligned with what I am expecting based on the maintenance schedule.  By the way the only weird thing I noticed is that there is another maintenance schedule shown that applied to the CI ("ServiceNow").  Is that the issue possibly?  I checked that other maintenance schedule and it does NOT have the ServiceNow CI listed on the "Configuration Items" tab for that other maintenance schedule so I am not sure why the scheduling assistant shows two maintenance schedules applying to the CI.

Hi @Chris Dea1 

 

A change come under conflicts with other changes or black out / maintenance windows , when

- CI matched with other change

- Plan start date / end match or with in the other change plan start / end date

Also 

Maintiance window is on multiple factor

- Parent Only

- Child CI

- Affected CI and more

so in your case you need to check this windows and see what is best time to deploy your change.
