CHaRM 7.1 API / BAPI

Hi,

I am looking to automate creation of the charm process by trying to create charms en masse programmatically via a z-program in SolMan 7.1

1. Are there any std BAPIs for charm creation ? Since charm is based on CRM can the std CRM BAPI CRM_ORDER_MAINTAIN be used ?
2. How do we handle assignment of charm specific attributes like Projects if we use the CRM BAPIs

I am surprised that there does not seem to be easy programmatic access to the business layer of charm(atleast did not see any documentation around it).

Regards,

Aditya
