Restrict Configuration Item field to specific type

[Mike Hashemi]

I am working on a migration project which will bring CMDB and Knowledge Management to ServiceNow. As I look to re-create the article types from our current knowledge management application, I am trying to figure out if I can add a CI field, but only for a specific type of CI.

I have created a knowledge article template with my desired text fields, and the "Configuration item" field, but I cannot figure out how to have the searcher only show a subset of CIs. In this example, I have a list of "PC backup application" CIs, from which article authors should be able to select.

Can this be done? Thanks.

Add reference field to Knowledge article form, referencing cmdb_ciXXX, XXX being whatever class of CI you want available. Or, reference cmdb_ci and use filter criteria.

// This is a sample script, adjust it based on your CMDB structure and criteria
(function executeRule(current, previous /*null when async*/) {

// Define the criteria to filter CIs
var filterCriteria = "u_category=PC Backup Application";

// Use GlideRecord to filter CIs
var ciGr = new GlideRecord('cmdb_ci');
ciGr.addEncodedQuery(filterCriteria);
ciGr.query();

// Build a comma-separated list of CI sys_ids
var sysIds = [];
while (ciGr.next()) {
sysIds.push(ciGr.getUniqueValue());
}

// Set the reference qualifier
current.addQuery('sys_id', 'IN', sysIds.join(','));

})(current, previous);
