Yes, you can configure a button to manually lock all the variables on a Requested Item (RITM) form. Here are the steps to do it:
1. Create a UI Action on the RITM table.
2. Set the UI Action to be a "Form Button".
3. In the script section of the UI Action, write a script to lock all the variables. You can use GlideRecord to get the current RITM and then use GlideElement's setReadonly method to set all variables to read-only.
Here is a sample code:
javascript
var gr = new GlideRecord('sc_req_item');
gr.get(current.sys_id);
var itemVariables = gr.variables;
for (var i = 0; i < itemVariables.getCount(); i++) {
var variable = itemVariables.get(i);
variable.setReadonly(true);
}
gr.update();
4. Save the UI Action.
5. Now, when you open a RITM form, you should see a new button. When you click this button, all the variables on the form will be locked.
Please note that this is a simplified example and you might need to adjust it to fit your specific needs. Also, keep in mind that making a variable read-only will prevent users from changing its value, but it won't prevent scripts or system processes from changing it.
