Enable the field TAX_CODE in BUS2202

Hi,

Does the possibility exist of enabling the field TAX_CODE in the quotation (BUS2202)?

The field is available in level of item of the structure BUS2202 but I don't see available in the portal SRM with supplier vision.

I want to turn possible that the supplier defines IVA.

I´m SRM 7.0 using NWBC.

Thanks,

Pedro Marques
