How to access Views of ERP with Netweaver BPM?

Hello,

i want to create an example-application with Netweaver BPM and Visual Composer.

For this, more employees should share the creation of a new Material in an ERP Backend.

Every emplyoee should enter data of a different View of MM01 ! (like Basic Data, Sales..., Purchasing., ..)

I thought about using the Service "Create Material Basic Data" but there are only little options for the data you can enter

(only InternalID, Base Units, Description...).

So my question is, how can i get access to the usual views of MM01 with Netweaver BPM and Visual Composer?

Or how can i enter more Materialdata with Webservices?

Thanks for your help,

Oliver
