[dkishore090]

Hi All,

When P1 or P2 incidents gets resolved automatically KB article should be created By using custom prompt from Business rule in Zurich.

Kindly share some suggestions/idea.

We have created some BR to achieve this, unlucky this BR not working .
Kindly share with your suggestions/inputs on this.

Table : Incident
Condition : after 
State changed To Resolved 
Priority is P1 or P2

(function executeRule(current, previous) {
  try {

    // ----------------------------------------
    // 1. PREVENT DUPLICATE KB CREATION
    // ----------------------------------------
    if (!gs.nil(current.u_kb_article)) {
      gs.info('[KB Auto-Gen] KB already exists for: ' + current.getValue('number'));
      return;
    }

    // ----------------------------------------
    // 2. FETCH FRESH INCIDENT VIA GLIDERECORD
    // ----------------------------------------
    var sysId = current.getValue('sys_id');
    var incGR = new GlideRecord('incident');
    incGR.addQuery('sys_id', sysId);
    incGR.query();

    if (!incGR.next()) {
      gs.error('[KB Auto-Gen] GlideRecord fetch failed for sys_id: ' + sysId);
      return;
    }

    gs.info('[KB Auto-Gen] Fetched incident: ' + incGR.getValue('number'));

    // ----------------------------------------
    // 3. BUILD PROMPT INPUT PAYLOAD
    // ----------------------------------------
    var promptInput = {
      number:            incGR.getValue('number')            || '',
      priority:          incGR.priority.getDisplayValue()    || '',
      short_description: incGR.getValue('short_description') || '',
      description:       incGR.getValue('description')       || '',
      close_notes:       incGR.getValue('close_notes')       || '',
      resolved_at:       incGR.resolved_at.getDisplayValue() || '',
      cmdb_ci:           incGR.cmdb_ci.nil()          ? '' : incGR.cmdb_ci.getDisplayValue(),
      assignment_group:  incGR.assignment_group.nil() ? '' : incGR.assignment_group.getDisplayValue(),
      resolved_by:       incGR.resolved_by.nil()      ? '' : incGR.resolved_by.getDisplayValue()
    };

    // 4. LOOK UP NOW ASSIST PROMPT BY NAME
    // ----------------------------------------

    }

    gs.info('[KB Auto-Gen] KB text (first 300): ' + kbText.substring(0, 300));

    // ----------------------------------------
    // 8. CREATE KB ARTICLE
    // ----------------------------------------
    var kb = new GlideRecord('kb_knowledge');

    kb.setValue('workflow_state',    'draft');
    kb.setValue('author',            gs.getUserID());

    var kbSysId = kb.insert();

    if (!kbSysId) {

    // 9. UPDATE INCIDENT WORK NOTES
    // ----------------------------------------
    var kbGR = new GlideRecord('kb_knowledge');
    if (kbGR.get(kbSysId)) {
