bapi_document_change2

hi!

i tried to use this bapi and change the status of existing document.

i imported the type, number, version, part, and the internal and extternal status.

i also entered this values to documentdata and documentdatax.

also in table documentfiles i entered these values.

i keep getting an error generation not supported for change object.

does any one knows what it means?
