Inventory Transfer from an excisable warehouse to a non excisable warehouse

Hi,

I had entered an Inventory Opening Balance document for a non-excisable item in an excisable warehouse by mistake.

Now I want to transfer that item from the excisable warehouse (01) to a non-excisable warehouse (06). When I try to create an Inventory Transfer document, I am getting the error: "Non-excisable items cannot be removed from an excisable warehouse". I have tried Duty Status as "With Payment of Duty" as well as "Without Payment of Duty". I am getting same error in both the scenarios.

Also, I want to know how can I cancel the Inventory Opening Balance document. I could not find the option anywhere.

Please suggest a solution.

Thanks.
