Issue setting field to readonly

[Mark9]

I'm trying to toggle the read-only property of the Next Step field (u_next_step) on the Service Record screen.  I have tried two approaches (UI Policy and Client Script) and neither approach works.  I know the code is being executed as I have added log statements to the console.  I also in the same code set sys_created_on to read-only (just to see that it works) and that field is being set to read-only while Next Step is not.  Both fields are initially editable in the form design.   When I create a new SR, the form loads and the Created field is grayed out but the Next Step field is not.

Here is the client script code:

function onLoad() {

    console.log('onLoad client script triggered');

    if (g_form.isNewRecord()) {

        console.log('This is a new record. The u_next_step field will be read-only.');

        g_form.setReadOnly('u_next_step', true);

        g_form.setReadOnly('sys_created_on', true);

    } else {

        console.log('Client Script: This is an existing record. Making the u_next_step field editable.');

        g_form.setReadOnly('incident.u_next_step', false);

        g_form.setReadOnly('sys_created_on', false);

    }

}

And here are the console statements

I'm sure this should be really simple, but I can't figure it out. Any help would be greatly appreciated. Thx.

Hi @Mark9 ,

Hi @Mark9 ,

There is no issue with code I checked in my PDI may be the issue is field sys_created_on and u_next_step may be mandatory from may be UI Policy or other Client Script or Configure Dictionary.

So that's why these 2 fields are not getting ReadOnly.

Please mark my answer correct and helpful if this works for you

Thanks and Regards
