Environment

Business Service Manager 4.0
Business Service Manager 4.5

Situation

You have created a large number blackout calendars and you want to remove calendars that are older than a particular date.

Resolution

Run the script provided on this TID, creating a server side operation is the normal approach.

1. Create a file called "deleteoldbo.fs" in the scripts directory. It must be that exact name.

2. Copy and paste all the code below the line into "deleteoldbo.fs".

3. The script defaults to purge blackout calendars older than six months, you can change this value.

4. Create either a server side operation or job to run the script.

Due to calendars that circularly refer to other calendars, you may need to run the script multiple time, to purge all the old calendars. The script will terminate if it detects a circular reference, but will attempt to break the chain by deleting at least one of the old calendars.
