Hello, I need some help. I'm a newbie and I'm using JDeveloper 12.2.1.4.0. How can I add validation in ADF table when inserting? My requirement was if the status of the person number is NEW and PENDING with same cycle, it will not insert to avoid duplication and it will insert only if the status is already set to PROCESSED For example, The UI page clicked the create button after inputting the data, when I click save button it should not insert because the person number and the cycle is already existing the table This is the functionality of the buttons Thank you.
