How to perform custom validation while receiving items in inventory

Content

Hello,

We have a requirement wherein we want to perform some custom validation before the user can receipt the items through "Receive Expected Shipments" screen under Inventory management. 

Only when custom validation returns true user should be able to create a receipt else he should a warning pop-up kind of thing with the message that receipts cannot be created.  Please refer to attached doc. where the custom validation needs to be applied.

Please let me know how we can achieve this kind of functionality within Oracle SaaS.

Appreciate your effort on this !!
