i have found a solution to making this work for both, Record producers via the Portal or via the Console.

script v2

Record Producer Script V2 and Steps to Implement

Enhancements

• Includes update to Record Producer Log table
• Support for attachments via both (portal and catalogue view)
• Fixes redirection issues inherited specifically from Helsinki instance.

Create record producer

1. name: (TfNSW) Dynamic Record Producer Test DEMO
2. table: sm_order
3. Script variables to check/modify
   1. thisRPsysID – current sys_id of the RP
   2. childTable – table of ticket to create dependent on form selection
4. Script:

//var message;

//Create Child Record base on selection of form
var childTable = 'hr_case';
var thisRPsysID = "184c35844f5e9700e8e846501310c751";

    var gr = new GlideRecord(childTable); //set the table for the child record.  
        gr.initialize();   
        //gr.parent = current.sys_id; - testing only
        //gr.(add whatever)
        gr.short_description =   producer.short_description;    
        gr.u_record_producer = thisRPsysID;
        gr.description = 'Dynamic Record Producer Records';     
    var childTask =   gr.insert();   

//Move Attachments based on form in the PORTAL or CONSOLE
if(producer.attachmentGUID == "record_producer") //checks if default value is set
{   
    //for Record Producers NOT on a Service Portal
    //Move Attachment - Find the Original and rename the attachement ID 
    //Attachments are stored in DB as soon as they are uploaded.
    var gr =new GlideRecord('sys_attachment');
        gr.addQuery('table_sys_id',current.sys_id);
        gr.query();
    while(gr.next())
    {
        gr.table_name = childTable ;
        gr.table_sys_id = childTask ;
        gr.update();
    }
}
else
{   
    //for Record Producers on a Service Portal 
    // grabs attachment variable that was created on the form.
    // this variable was populated and hidden via a widget client script
    // source of the attachment ID is taken from the portal widget "reco" hiddent div tag has value bind to id
    var gr =new GlideRecord('sys_attachment');
        gr.addQuery('table_name','sp_portal');
        gr.addQuery('table_sys_id',producer["attachmentGUID"] );
        gr.query();
    while(gr.next())
    {
        gr.table_name = childTable ;
        gr.table_sys_id = childTask ;
        gr.update();
    }
}

//Variables
//Dynamically creates variables for child record
//Can't move variables as they aren't created yet. 
// i.e producer.varableName1, producer.varableName2, … etc
    var v;
    var pastV;
    var vID = ""; 
    var order;
    for (var key in producer) 
    {
        v = producer[key];
        if (pastV != v.getED()) //Exclude sequential  duplicate variables
        {
            pastV = v.getED(); //sets past variable - skip sequential duplicates
            vID = v.getED().toString().substring(2); //Gets sys_id of variable
            if(v.getTableName() == 'variable') //Excludes other keys
            {
                // values that can be pulled from the producer[key].   Debugging.
                //gs.addInfoMessage('P:/' + v + " - " + v.getDisplayValue() + " - " + v.getED() + " - " + vID ); 
                //message = message + "<br/>" + key + "|" + v.getED() + "|" + v.getTableName() + "|" +  v.getDisplayValue() + "|" + v + "|" + vID;   

                //Query to get order of the given variable
                //Only important if using the 'variable editor' UI formatter
                var vOrder = new GlideRecord("item_option_new");
                if (vOrder.get("sys_id", vID)) order = vOrder.order;

                //Insert variable into Question Answer Table.
                var gr3 = new GlideRecord('question_answer');   
                gr3.initialize();   
                gr3.table_name = childTable ;
                gr3.table_sys_id = childTask ;
                gr3.value = v;
                gr3.question = vID;
                gr3.order = order;
                gr3.insert();     
            }
        }
    }

//gs.addInfoMessage(message);

//update sc_item_produced_record table which relates a Task (table: task) record to the Record Producer (table: sc_cat_item_producer) that created the Task. 
    var rpTask = new GlideRecord("sc_item_produced_record"); 
    rpTask.initialize();
    rpTask.record_key = childTask;
    rpTask.record_table = childTable;
    rpTask.task =   childTask;
    rpTask.producer = thisRPsysID;
    rpTask.insert();

//redirect to child record6
if(producer.attachmentGUID == "record_producer")7
{
    producer.redirect= "/" + childTable + ".do?sys_id=" + childTask; //non portal redirect
}
else
{
    producer.portal_redirect = "?id=ticket_nsw&table=" + childTable + "&sys_id=" + childTask; //portal redirect 
}

//stops parent record being created,
//stops parent variables being created 
current.setAbortAction(true); 

Amend Existing Record Producer widget (sc-catalog-item)

1. Add Attachment Guid HTML code
   1. This line binds the generated ID into this element for retrieval via the widget script, it is added as a hidden DIV at the top of the form

<div style="visibility:hidden;display:none;" id="_attachmentGUID"  ng-bind="c.data._attachmentGUID"></div>

Create Widget Client Controller

1. Name: (TfNSW) Dynamic Record Producer – Attach
2. Description: Collects the attachment ID from the reco widget to then store in the hidden varaible for processing
3. Client Script:

4. function($scope) 
   {
       var c = this;
       var attachID = document.getElementById('_attachmentGUID');
       var g_form = $scope.page.g_form;
       var g_field = $scope.page.field;
   
       g_form.setValue("attachmentGUID", attachID.innerHTML);  
       g_form.setReadOnly("attachmentGUID", true);
   
       // Hide variable after testing - must be dont this way to preserv value
       var attachmentGUID_field = document.getElementById('c59fb9084f5e9700e8e846501310c7bd'); // variable field
       attachmentGUID_field.style.display = "none";
       attachmentGUID_field.style.visibility = "hidden";
       //g_form.setDisplay("test_variable",false); // stops submission of field
   }
   

    

Create Variable – Place holder for Macro Widget Script

1. Question: attachmentGUID
2. Name: attachmentGUID
3. Default Value: record_producer
4. Type: single Line Text

Create Variable – MACRO runs script to populate other variable with attachment ID

1. Type: Macro
2. Question: get_attachmentGUID
3. Name: get_attachmentGUID
4. Widget: (TfNSW) Dynamic Record Producer - Attach

updates to Record Producer script

better filtering for reference variables 

additional script to run workflow on child task

if( (v.getTableName() == 'variable' || !v.getTableName())) //Excludes other keys // null is used cause reference variables not showing
            {
                var vOrder = new GlideRecord("item_option_new");
                if (vOrder.get("sys_id", vID))
                {   /****/
                    gr3.insert();     
                }
            }
       


//Set ADHOC workflow to run
var gr2 = new GlideRecord(childTable);
    gr2.get(childTask);

var wf = new Workflow();
var  wfId = wf.getWorkflowFromName("****AdHoc");
var vars = {};
vars.u_approver = producer.approver_1;
//vars.u_app ='';
//vars.u_a_phase ='';
wf.startFlow(wfId, gr2, "insert", vars);
