Hello Gisele, SAP Business ByDesign is a full cloud ERP, accessed via browsers, with manufacturing capabilities, which also manages custom products (it is named "Product Specification"). Each product specification can have a different BoM and production route. Please contact me at firstname.lastname@example.org to get more details of your need and I can help you out to define if this is suitable for your company. This is not the big SAP product. It is an affordable full cloud ERP designed for Small and Medium sized enterprise, which is also being used by bigger companies.
