I have a custom object. There are combination of fields like month_c,Project_c,contact_c and role_c which determine the record as unique.
I can write a trigger on before insert to check if there are any records with the same combination already existing. The question i wanted to ask was
how can i make the insertion stop. once i find there is already an record then it should just not insert the record. it doesnt need to throw / show an error.
Thanks
