Using BAPI_DOCUMENT_CREATE2 to create a document and checkin to VAULT

Question

In a development we are using the function module BAPI_DOCUMENT_CREATE2
to create a document and check in the original file into the R/3 storage
system in one go (see subroutine below).
However, we got the requirement to use a Vault ("Tresor") as the storage
backend. Unfortunatly, just setting the documentfiles-storagecategory element to 'VAULT' results in 3 things:
- the document gets created OK
- the original file does NOT get checked in
- the error message "Original 1 wurde bereits eingecheckt und abgelegt" (...has already been checked in)
So please advise how to use the BAPI modules to achieve the checkin into
a Vault storage.
Could this have something to do with the undocumented documentfiles-originaltype element? What does this have to be set instead of the '1', thats working with SAP-SYSTEM storage?

Hi Frank,
Did you manage to figure out what the problem was?
Thank you.
