How To Validate Duplicate Extensible Flexfield (EFF) Attribute on Sales Order through OM Extensions
If user enters an EFF Attribute Value on Sales Order Header that already exists on another Sales Order, system should throw an error. A sample code is available on Oracle Support for Customer PO Number but we need to apply validation on EFF Attribute Header Level. I have tried to use following documents to create a code but it's not working. I have uploaded a document and mentioned complete steps that I performed. Please suggest what I am missing here.
