If Coalesce failed record should not create

[SANJEEV4]

I have a requirement. We should not create a single record when coalesce fails(coalesce for update only )

That should be updated only.

I created onBefore with 

if(action == 'insert'){
ignore=true}

//Still it's creating new records

script looks good.

Did you check the action object contains what value?

what came in logs?

@Ankur Bawiskar Value is insert

Can we use this

if(action == 'insert'){
ignore=true
return;
}
