Receivables Debit Memo WebServices with DFF

Summary:

We understood there is no  API for Debit Memos Transactions, hence we are using SOAP Webservice Debit memo.

But could not find any field to pass DFF (Descriptive Flexfield)

Content (required):

Is there any way we could create debit memo with DFF by SOAP Webservice or API?
