Hi @sadhna 

The CMDB Identification API error message is saying you don't have enough unique attributes returning from Discovery to be able to attempt matching to the CMDB.

By default, the Hardware Rule should be set up to identify items . However, it seems that either this Identifier Entry has been altered or a new Identifier has been created from the extended tables of Hardware (computer, server), and it lacks the necessary entries to function properly.

OR

There is a system property for CMDB Identification and Reconciliation process that enforces mandatory fields and prevented discovery updating.

Mark it Helpful and Accept Solution!! If this helps you to understand.

So what should I do to fix this error, change identifier entries?

Hi @sadhna ,

Two things to be checked :

1. See if the target table has sufficient Identification rule / attributes configured.

2. Copy the input payload that you received only the Json of the result and go to navigator and search for  > identification simulation module

>Click on >  start exploring exisitng json

>Data source > servicenow

>paste the json and click on run simulation 

Here you will get the actual error which is responsible for the above error that you shared. I Assume this may be because of duplication of CI attribute value.

start exploring this way... i hope this helps...
