Reference field being set by business rule is getting sys_id but it's not displaying correctly

[e_wilber]

I have no idea what's going on.

This field is being set in a business rule (you can see there's a sys_id attached to it but it's empty):

The field data looks like: 

//patient is the sys_id as a string

var wot = new GlideRecord('wm_task');
wot.initialize();
wot.parent = ev.u_work_order;

wot.u_patient = patient;

wot.insert();

Why isn't this field being set correctly?

Hi @e_wilber ,

Hope you are doing well.

Try using below script for setting the reference field value:

var wot = new GlideRecord('wm_task');
wot.initialize();
wot.parent = ev.u_work_order;
wot.setValue('u_patient', ' <sys id o patient which your want to set>' ) 
wot.insert();

And also make sure to check the referencing table has exactly once column with display ="true".
