Facing Issue in copying Comments from parent to child and child to parent

[i_sachin_]

Hi Servicenow community, I'm actually facing a problem in copying comments  from incident to work order and from work order to work order task, then copying work order task to work order and incident. The comments added by users in the portal will go from incident to work order to work order task, and the comments added by technicians will go from work order task to work order to incident. However, when I do this, it actually recurses, copying the same comment again. How can I resolve this issue?

I'm attaching my business rule code here,

when to run: after update

filter condition: comments changes

Business rule for Incident to work order:

(function executeRule(current, previous /*null when async*/ ) {

    // Add your code here

    var WO = new GlideRecord('wm_order');

    // check for exising record.

    WO.addQuery('parent', current.number);

    WO.query();

    if (WO.next()) {

        var commentstext = current.comments.getJournalEntry(1);

        commentstext = commentstext.replace(/.*\)\s*/, '');

        WO.comments = commentstext;

var WorkOrderID = WO.update();

    }

})(current, previous);

when to run: after update

filter condition: comments changes

Business rule for Work Order to Work order task:

(function executeRule(current, previous /*null when async*/ ) {

    // Add your code here

    var WOT = new GlideRecord('wm_task');

    // check for exising record.

    WOT.addQuery('u_parent_wot', current.number);

    WOT.query();

    if (WOT.next()) {

        var commentstext = current.comments.getJournalEntry(1);

        commentstext = commentstext.replace(/.*\)\s*/, '');

        WOT.comments = commentstext;

var WorkOrderID = WOT.update();

    }

})(current, previous);

and two more business rules are there, when to run: after update and filter condition: comments changes. These rules handle copying comments added by technicians from work order tasks to work order and then Work order to incident

@Ankur Bawiskar can you help me with this?
