SAP SRM using Fiori: Price field not editable at item level

Hi

We have installed Fiori component to implement creation and approval of SRM shopping carts.

We don't use any catalogs( neither external punch-out catalogs nor MDM Internal catalogs) and only use either Material(Internal goods and services) or Limits options

We observe that the " Price" field in not editable at the line item level. How to make this editable?

Any pointers are highly appreciated.

Thanks
