How to save file on ECC DMS through Portal

Hi Guys,

We are developing a CE based application. We have the following layers:

1) Display Portal

2) CE Portal (Contains all CE app logic and WebDynpro)

3) XI

4) ECC (Back End)

Basically we know that if you were to use the WebDynpro "Upload File" UI element you can link it to a Model that saves the file where ever you need to save it to.

So:

Are there any BAPI's/services that van be used to save a document that is uploaded in Portal to ECC DMS? We can then import these as Advanced Service Models into WebDynpro and use their functionality.

Any other suggestions?
