[atharvabharekar]

Hello,

I'm extending my inbox PO approval app, the requirement is to add custom fields in master page in SAP BTP BAS.

Below are the fields

1.Supplier ID

2.Purchase Order

3.Landed cost

4.Vendor name

Can anyone please guide me on how this can be achieved, as this is new to me,

Thanks & Regards,

Atharva
