BPC 10.1 NW: Document upload and location

Dear All,

I have a requirement to upload documents to the BPC server so those can be referred for each project. The tricky part here is that the document should be uploaded from BPC excel application. All the documents related to one project should go to one directory and while retrieval that directory should come up to select the relevant document.

Is there any possibility to find out the location or any FM/BAdi to upload/download.

I have gone though the link

but the epm formula only takes me to document screen and not at the upload screen and users do not prefer to specify whole of context, only the project code should be enough for upload and download.

Any pointers will be greatly helpful.

Thanks
