User defined relationship types (BINRELTYP)

Hi,

we are creating via document flow between two activities using 'VONA' inter-linkage relationship type (BINRELTYP). However, we need more specific relationship: Instead of 'preceding/next document', role text should be 'created automatically', for example.

(The document flow is created automatically using 'BAPI_ACTIVITYCRM_CREATE' and other function modules).

Is it possible to create user-defined relationship type?
