I have created an Item in Released Products Form. I have deleted the same item in Released Product List page "Delete" Button. Record is deleted from InventTable Table. But The same Item details not deleted in EcoResProduct Table and it's associated tables.
Can anyone help me to solve this issue?
Aren't you trying to create the same product again? That must fail, because it already exists. You should release the product to the given company, not trying to create the product again.
