How to copy one Reference Field Value into another

[bammar]

Hello All,

This seems so easy on the surface but I have been unable to copy one Reference Field to another ( even the Eureka Actions tab doesnt let you do this when creating a business rule).   I have one reference field ( Approval For)   that has a value in it. I can pull the value and even display it as message. However I can not populate this value into another reference field ( Change Number)     leaving me to have to type it in. Both fields reference the the Change task list,   I would love it if someone could show us very simply how to extract from field A and input into field B.   I know reference fields rely on things like Display Values and sys_ids. I have tried every combination of methods and tried using   getDisplayValue()); to get the original Value and   g_form.setValue to   as well as scowering the wiki /community . Thank you in Advance, there are many applications for why anyone would need to do this , this is just one of them.

BR - After, on insert or update of approval form

findChange();

function findChange() {

  var ri = new GlideRecord("sysapproval_approver");

    ri.get('sys_id', current.sysapproval);

//this does display the correct value when I save the form.

  gs.addInfoMessage(current.sysapproval.getDisplayValue());

// trying to get an acceptable value for which I can pass into set the   destination field , this is unsuccessfull

var change =   current.sysapproval.getDisplayValue();

            g_form.setValue( 'u_change', change);

}

Kalaiaran.   Thank you so much. Perhaps others also alluded to this but I didnt understand without the full code.   The script is so simple and works.   I am not sure why I had such an immense amount of difficulty.   I have to do the same thing now   on the Change From copy- Opened by into Assigned to - so i will try to use the same principal

we cant use g_form in BR. Instead we can directly set value as below

current . <field name>=<your value>;

When your field is of reference type we need to give sysid as the value.

Can you expand on that please. instead of G-form what do we do to fetch this sys id from field one.

Run this code

function findChange() {

  var ri = new GlideRecord("sysapproval_approver");

    ri.get('sys_id', current.sysapproval);

//this does display the correct value when I save the form.

  gs.addInfoMessage(current.sysapproval.getDisplayValue());

// trying to get an acceptable value for which I can pass into set the   destination field , this is unsuccessfull

var change =   current.sysapproval.getDisplayValue();

  current.u_change = current.sysapproval;

}

Anurag,

i really appreciate your time and help. This did not work, i beileive it has to do with getting the sys_id of the reference field, usually fields can be copied with the method you outlines if they are say string fields. If you want try in your own test instance, copying one reference field to another, replacing my fields with yours, it is proving quite challenging.
