Process 1 :

Step 1:

Create below Script Include :

var C_AttachmentUtils = Class.create();
C_AttachmentUtils.prototype = {
    initialize: function() {
    },

    copyAttachment: function(attachmentId, receiverTable, receiverId) {
        var grAtt = new GlideRecord('sys_attachment');
        if (!grAtt.get(attachmentId)) {
            return -1;
        }
        var grTab = new GlideRecord(receiverTable);
        if (!grTab.get(receiverId)) {
            return -1;
        }

        grAtt.table_name = receiverTable;
        grAtt.table_sys_id = receiverId;
        grAtt.setWorkflow(false);
        grAtt.autoSysFields(false);
        var newAtt = grAtt.insert();

        var grAttDoc = new GlideRecord('sys_attachment_doc');
        grAttDoc.addQuery('sys_attachment', attachmentId);
        grAttDoc.query();
        while(grAttDoc.next()) {
            var grNewAttDoc = new GlideRecord('sys_attachment_doc');
            grNewAttDoc.initialize();
            grNewAttDoc.data = grAttDoc.data;
            grNewAttDoc.length = grAttDoc.length;
            grNewAttDoc.position = grAttDoc.position;
            grNewAttDoc.sys_attachment = newAtt;
            grNewAttDoc.setWorkflow(false);
            grNewAttDoc.autoSysFields(false);
            grNewAttDoc.insert();
        }

    },

    type: 'C_AttachmentUtils'
};

Step 2:

Configure Below Async Business Rule and call the above script include in the script section :

Table : sys_attachment

When : Async and Insert

Filter condition :

Table Name is sc_req_item

Script :

(function executeRule(current, previous /*null when async*/) {
    var attUtil = new C_AttachmentUtils;

    var gr = GlideRecord('sc_task');
    gr.addQuery('active', true);
    gr.addQuery('request_item', current.table_sys_id);
    gr.query();
    while(gr.next()) {
        attUtil.copyAttachment(current.sys_id, 'sc_task', gr.sys_id);
    }

})(current, previous);

Process 2 :

Step 1:

Configure Below After Business Rule :

Table : sys_attachment

When : After and Insert

Filter condition :

Table Name is sc_req_item

Script :

var id = current.table_sys_id;
var gr = new GlideRecord('sc_req_item');
gr.addQuery('sys_id', id);
gr.query();
var ritm_num = '';
if (gr.next()) {
ritm_num = gr.number;
}


var gr_task = new GlideRecord('sc_task');
gr_task.addQuery('request_item.number', ritm_num);
gr_task.query();
if (gr_task.next()) {
var ritm = gr_task.sys_id;
var att = new GlideRecord('sys_attachment');
att.initialize();
att.file_name = current.file_name;
att.content_type = current.content_type;
att.compressed = current.compressed;
att.table_name = 'sc_task';
att.size_bytes = current.size_bytes;
att.size_compressed = current.size_compressed;
att.table_sys_id = ritm;
var attRec = att.insert();
var attDoc = new GlideRecord('sys_attachment_doc');
attDoc.addQuery('sys_attachment', current.sys_id);
attDoc.query();
if (attDoc.next()) {
var attDocCopy = new GlideRecord('sys_attachment_doc');
attDocCopy.initialize();
attDocCopy.sys_attachment = attRec;
attDocCopy.position = attDoc.position;
attDocCopy.length = attDoc.length;
attDocCopy.data = attDoc.data;
attDocCopy.insert();
}
}
