Creating Custom BO with upload function like 'Import Supplier Invoices' App in S4hana Cloud

[ayechan]

Hi Experts,

I would like to create a custom business object with upload function like Import Supplier Invoices App in S4Hana Cloud system.

Is it possible to create that kind of custom business object using Key User (In App) Extensibility or Developer (On Stack) Extensibility using ADT?

Or any workaround exist?

Could you please provide any idea?

Thanks in advance.

Best Regards,

Aye Chan
