Modify a Business Package without NWDI

Hello,

I am trying to modify an ESS Business Package in a system where I want to NOT install NWDI. I have search this forum on how to do that but everything I find is related to NDWI.

So, is it possible to modify a Business Package (or a SCA file) without NWDI ? Or is this tool absolutely necessary ?

Thanks in advance.

Best Regards,

Greg.
