Insert new record in MDF existing data should not be given twice

233 Views

hello,

I have a requirement from the client where for one custom MDF if the data is saved and when we need to insert a new record in that same data cannot be given twice if so then the error message should populate.

If anyone know the solution or any suggestion then it would be a big help.

P.S: I created a two objects one is parent and another one is child. the fields are in child object and the rule that I wrote is also for child object.

Thanks
