Changing Material Document Type while Posting GR

Hi,

Is it possible to change the document type of material document number while posting the GR.

The method MB_DOCUMENT_BEFORE_UPDATE of BADI MB_DOCUMENT_BADI has all the necessary parameters required to change the document type.

I do not have any data with me as of now, so just need a confirmation whether this is possible or not.

If not possible, any other process ???

Thanks in Advance

Amol
