Hello Community
Looking to find some expert advice around a typical scenario we have.
We are allowing users to create CIs that are not present in CMDB. All of these CIs if not matched (name) , will go into an Unclassed CI table which is a new class.
Later we want IRE to run on all these records and match it against any other valid CI Class based on name field , and reclassify the unclassed CI to the correct class.
We are not sure if this can be achieved. If yes , then how?
Couple of questions :
1. What will be the identifier rules on Unclassed CI table ?
2. Can we run this IRE as a nightly job when our CMDB load has happened via the correct source.
Clarifications :
1. We cannot avoid the manual entry of CI. That is a requirement
2. Immediate run of IRE on insert might not be possible since the data load from correct source happens during the evening.
Regards
Nitin

Automatic CI reclassification is enabled by default in ServiceNow. The following URL has details about this and how it can be configured:
But I would strongly recommend a change in the process instead. It is not a good idea to allow too many users to create and modify CIs. The users should be rather given an option to raise a service request if they need to load data manually. Then the configuration management team or CI class owners can review the data and get it loaded to the most suitable CI class. Following are the main reasons why I recommend this:
1. Avoid the use of an unnecessary custom table for the unclassed CI class
2. Reclassification won't happen for CIs which are not discovered and so there is possibility of undiscovered CIs remaining as unclassified
3. CI reclassifications can lead to data loss if the new CI class does not have any of the populated attributes that are present in the current CI class.
