You are trying to create a business partner with a certain role, but the option required is unavailable for selection.
SAP Business ByDesign 1711 and higher.
Reproducing the Issue
Go to the Business Partner Data work center;
- Access the Business Partners view;
- Select an existing business partner;
- Click the Create As button;
- Some options are unavailable.
The system has two main Business Partner types: organizations (which represent companies) and persons (which represent individuals). Certain roles are exclusive to business partner organizations and others, exclusive to business partner persons — e.g. an Employee cannot have the Supplier role assigned to it, because the Employee is a business partner person and the Supplier role is for business partner organizations.
This is the standard system behavior.
