Bapi for debit/credit memo creation

Dear all,

I am using the BAPI_SALESORDER_CREATEFROMDAT2 for creating a credit/debit memo, the following error is displayed.

"Unpermitted Combination of Business object BUS2032 & Sales Doc Category type K"

Could you please provide me a solution and let me know if there are any BAPIs to create credit/debit memos.

Thanks in Advance.

Regards,

Raj
