Make field read Only after submission

[riaz_mansuri]

Hi,

I have added a new Choice Field on my Change Request form called Submitted As and is open for users to select a drop down option.

Once the change has been submitted I was this field to become Read Only.

A change would be classed as submitted when the state changes to Open or is Work In Progress.

Any Ideas?

Thanks

Riaz

Hi Riaz,

This requires an ACL (security rule)

You can use the GlideRecord method isNewRecord() to determine if the record has been saved or not. In you case, you want to grant the field write permission if current.isNewRecord().

I think this is the correct answer. If we look into from the security standpoint, ACL is actually restricting the field from editing in the database, rest all are client side restriction.

Hi Riaz,

You can use a onLoad Script with conditions,

if(g_form.isNewRecord){

g_form.setReadOnly('field_name',false);

}

else{

g_form.setReadOnly('field_name',true);

}

Mark correct and helpful if it works

Keep in mind that client side security is not secure. A clever user with a minimum of browser knowledge can change a read-only field that has been set with client scripts or UI policies. To ensure compliance, use server side security whenever possible.
