Delete of a CI "xyz" is not allowed because of a reference in record "abc" Issue When tried to delete a CI, the error "Delete of a CI "xyz" is not allowed because of a reference in record "abc"" is observed.ReleaseNew YorkCauseThis is because of CI "xyz" referencing in the CI record "abc"ResolutionA new field "Duplicate Of (duplicate_of)"has been introduced into the cmdb_ci tables since NewYork release. This field is a reference to CIs. On the insert of a CI with the Identification and Reconciliation Engine, if the CI is detected to be a duplicate of 2 or more CIs already in that CMDB table, then the CI with the earliest "created" date will be referenced by each duplicate CI from the Duplicate Of field. The updates from the inserted CI are updated to the CI with the oldest created field unless the "glide.identification_engine.skip_duplicates" is set to "false". In that case, the insert is rejected. Performing the below should fix the issue: Please set the 'Duplicate of' field to empty on the CI "abc".Now delete the original record.
