Hi,
I have a flat list to maintain the certification records of the employees. Users will make use of that list in order to update the certification. If a user comes up with a new name then that name will get added to the list. But the problem now is that the names are not standardized and as a result we are getting same name certification twice or thrice. e.g., 1. SAP_Certified_Admin & 2. SAP Certified Admin(SPA). (This is just for the sake of example and not a real name)
How can this be made sure that if a user wants to add a new record for certification for SAP Certified Admin then he can only add one of the either names, also once added there should be an error message saying that the name already exist if any other user is trying to add the same record with another name.
