How to Make future catalog task & RITM read-only after 2nd catalog task in catalog item

[Naresh_5120]

Dear Community,

I have a catalog item , after submission of this , it generates total 5 catalog tasks, what i want is when the 2nd task short description of task " Agreed date completed" is closed, i want to make future catalog tasks and RITMs variables read only.

I have tried this through UI policy and catalog client script but its not working. Any guidance would be really helpful!

@Naresh_5120 May I know the use case here for making the tasks readable? Ideally, this can be achieved via a combination of catalog client script having a GlideAjax call to a client callable script include which should check the status of the 2nd task and return true/false to make fields editable/read only.

Business case is there is 2nd task called "agreed date " after completion of this task, business want to stop further modification in future catalog and RITMS variables (fields)

@Naresh_5120 As suggested earlier, please try the combination of GlideAjax + client callable script include. Based on the response receive from Server. Make all the fields read only.

@Naresh_5120 

you can use onLoad catalog client script + GlideAjax which runs on sc_task and sc_req_item

that will check if the 2nd task is closed or not

Script Include: It should be client callable

var YourScriptIncludeName = Class.create();
YourScriptIncludeName.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    checkPreviousTaskClosed: function() {
        var recordId = this.getParameter('sysparm_record_id');
        var table = this.getParameter('sysparm_table');
        var parent = null;

        // Determine parent (RITM) based on table
        if (table === 'sc_req_item') {
            parent = recordId;
        } else if (table === 'sc_task') {
            var task = new GlideRecord('sc_task');
            if (task.get(recordId)) {
                parent = task.request_item;
            } else {
                return 'false';
            }
        } else {
            return 'false';
        }

        // Get all tasks for the parent and check if the previous "Agreed date completed" task is closed
        var tasks = new GlideRecord('sc_task');
        tasks.addQuery('request_item', parent);
        tasks.orderBy('sys_created_on');
        tasks.query();

        var foundCurrent = false;
        while (tasks.next()) {
            if (table === 'sc_task' && tasks.sys_id == recordId) {
                foundCurrent = true;
                continue;
            }
            if (!foundCurrent) {
                if (tasks.short_description == 'Agreed date completed' && tasks.state == '3') {
                    return 'true';
                }
            }
        }
        return 'false';
    },
    type: 'YourScriptIncludeName'
});

onLoad Catalog Client Script: Which Applies on Applies on Catalog Tasks = True and Applies on Requested Items = True

function onLoad() {
    var table = g_form.getTableName();
    var recordId = g_form.getUniqueValue();
    var ga = new GlideAjax('YourScriptIncludeName');
    ga.addParam('sysparm_name', 'checkPreviousTaskClosed');
    ga.addParam('sysparm_record_id', recordId);
    ga.addParam('sysparm_table', table);
    ga.getXML(function(response) {
        var answer = response.responseXML.documentElement.getAttribute("answer");
        if (answer === 'true') {
            g_form.setVariablesReadOnly(true);
        }
    });
}
