Unpermitted combination of business object BUS2032 and sales doc. category

Dear all

I try to create a sales document category L (Debit memo request) with the BAPI BAPI_SALESORDER_CREATEFROMDAT2

I get the error message: Unpermitted combination of business object BUS2032 and sales doc. category L

Is there a specific Bapi for creating this sales document?
