Biml allows users to create SSIS packages without using the VS interface. This allows for much quicker package creation. Database Mapper cannot document SSIS packages made with Biml due to the lack of (x,y) coordinates for the layout that VS typically creates. This is because the documentation generated by Database Mapper relies on the XML used within VS, which BIML does not need and therefore does not provide it to the packages.
As a workaround, you need to adjust an object's position slightly within the package(s) or do an autoformat on the package(s) before saving and deploying them. This extra step should generate a package layout, allowing Database Mapper to document the package(s).
