I have to do form personalization so that user cannot enter duplicate items in the PO.
At when-new-item-instance in PO-Approve field, I have created a database function that is taking the count of items and returning the count value.
In the condition I have given condition:
1<(select func_name(parameter) from dual)
10 message duplicate items in the po
But its not working fine.
Thanks & Regards
