Title In Detail page

Hello,

Mostly seems that you have a method on the page of this detail that declares this name of a record. At least it takes the name of the opportunity from which the record was created and adds Opp Critical Path 1 to the name. If you don't have this method - you should create one like concatenation of some fields and after that insert parent Save method so to save the record. Or you can create a business process that will change the name of the record in this detail using values of some other fields.

Best regards,

Oscar
