Batch field as input field for Non-stock items in PM Order component TAB

Dear Gurus,

Batch field as input field for Stock items (Item Category - L)in PM Order component TAB

However for Stock items (Item Category - N) in PM Order component TAB, this Batch field appears as display field and picks up valuation type "New" as default.

We would like to have this as input field for item category "N".

Appreciate prompt response.
