I have a "Service Line" when a waiter wants to adds a line for a product to sell to a customer in hotel but when they create the product I want them to delete that line if the product is incorrect.

I have set "perm_unlink" to user group and nothing happened. I also went to admin user > settings > technical > models and set that model to delete access for users group but still nothing happened. Can someone please tell me what to do?

@Waleed Mohsen thanks for the comment, im not getting any error just from users can't delete service lines

Hi Ricky Low,
Correct me if I am wrong. Is the product added is an one2many field and Service line is parent model?
If yes, Have you added the delete access to Service Line model and the one2many field model aswell?
