  The SAP error message VMD_API100 indicates that a mandatory partner role is missing for a vendor in a specific purchasing organization. This error typically arises when you are trying to create or modify a vendor master record, and the system requires certain partner roles to be defined for the vendor in the context of the specified purchasing organization.
  Cause:
  The error is caused by the absence of a required partner role for the vendor in the purchasing organization.
