The document provides instructions for storing and deleting PDF documents in the SAP content server for the FI module. It outlines the new process for attaching documents by storing business documents rather than creating attachments. Only PDFs can be stored currently. The instructions describe selecting the appropriate category for the document, dragging and dropping or selecting the file, and adding an optional description. It also notes an increased file size limit of 100MB and viewing attached files in Adobe. Deletions can now only be performed by designated central roles and require attaching a correcting document instead of deleting in most cases.
