Add a task to a ITAM Purchase Order

[clktester]

Using OOB ITAM Purchase Order form, I've created a catalog item to request a Purchase Order. 

I would like to generate a series of Catalog tasks that show in the related lists on the proc_po form. 

I've been able to create a relationship from the proc_po table to the sc_task table, then add it to the proc_po form and see it. 

I can click New on this related list and create an sc_task manually and that works. 
I've added a field to the sc_task table called Purchase Order and made that a reference field to the proc_po Number field. 

I just can't see that task in the related list, even though it's there. 
I am not certain what to put in the relationship script field to accomplish this. 
Thank you in advance if you have any ideas.

Hi @clktester ,

You can try the below script-

var gr = new GlideRecord('sc_task');
gr.addQuery('proc_po_number', current.sys_id); // 'proc_po_number' is your reference field in sc_task
gr.query();
return gr;
