Upload File to ECC using PI

I am new to PI.Can you please help me with the below scenario using PI.

We have PDF files on a server drive that is NFS mounted to the PI system. We need create a DMS document and attach these files to the document.

We have a BAPI that can upload pdfs as DMS documents (CV01N t-code). How do I use PI to call the bapi (BAPI has the file and path as parameters).

I configured DMS document type to external numbering. I have to read the file name to take the 1st 10 chars of the file name to use as the document number. This will be unique by design.

BAPI is working within ECC.

Please help with steps in PI to move the file from External NFS mounted drive to ECC and then call this BAPI.
