Creating or Update Bill of Material using eConnect?

Hello everyone,

I am trying to build an integration to GP 2013  which will create/update items and BOMs.

eConnect allows the creation/update of Items, but it has no support for Bill of Materials from what I see.

Is there a way to modify a BOM in GP 2013 using eConnect or web services or existing stored procedures?

I could do some reverse engineering and directly update the SQL tables but it is messy.

Please let me know if you provide any help or insight.

Thanks!
