Hi everyone,

Hi Lokesh,

Can you clarify further please? 

1. Do you mean is there a way to check for duplicate data across different records?
2. Do you mean is there a way to check for duplicate picklist values having been selected on the same field? 

If no 2., then you would just need to ensure that you remove the duplicate picklist values on that particular field in Setup --> Create --> Custom Object Name --> Field Name

You can run a report on your existing data to find out what the current values are that might need de-duping. 

If you wish to de-dupe records, then you might want to install an app from the AppExchange - possible suggestion are here:
