How do i omit a New button on a related list When the list is not empty?

Open the related list table's UI actions search for the "new" ui action and on the new ui action form view uncheck the list banner button checkbox 

It will remove the new button from related list 

For e.g On the incidents form if you want to remove new ui action from child incident  related list then type incident.config > UI action> select the new ui action  button> on the new ui action form view uncheck the list banner button checkbox 

Note : As I was doing removing the new button from child incident i have navigated to incident table 

          If you want to remove from any other related list the table will be differ keep in mind

An idea:

1. Create a before display business rule and calculate the number of the related records (use GlideAggregate)
2. Put the value in g_scratchpad container
3. Copy the global UI action "new" for related list to your specific table with the same action name
4. In the condition line of the UI Action check g_scratchpad content.

NOT tested!

Hi @Linda Eju 

You can do a simple query to validate if there're existing records associated to the parent or not.

Sample below.

var gr = new GlideRecord(current.getTableName());
gr.addQuery('task', parent.getUniqueValue());
gr.setLimit(1);
gr.query();
answer = gr.hasNext();

Hi @Linda Eju ,

I checked your problem and tried in my PDI and it working fine for me 

Before : 

After: 

Right click on related list and click "List Control".

Add below code and it will work 

var answer ;
gs.log("Checck log incidnet 222 = " + parent.child_incidents);

if (parent.child_incidents <= 0) { //Do not remove the 'New' button
   answer = false ;
}
else { //Remove the 'New' button
   answer = true ;
}

answer ;

Please mark correct and helpful if it works for you

Thanks and Regards
