@Eranda10274 When using the FilePath Controller in Pega to upload a document, the pyAttachStream (which stores the file content) is available on the pxRequestor.pyFileUpload page after the file is uploaded. To store this data, you can create a new Data-WorkAttach-File instance and set the pyAttachStream along with other details like pyFileName and pyNote. Save this instance using an Obj-Save step in an activity. Avoid storing large files directly in the work object to prevent performance issues. Instead, store the file in a separate data class and reference it in the work object using a link or identifier. If the file needs to be retained for reporting or long-term storage, you can also use external storage like a content management system. This approach ensures better performance, easy data retrieval, and proper file management in your Pega application

@Eranda10274If the pxRequestor.pyFileUpload page is empty after using the FilePath Controller in Pega, it means the file data is not automatically captured in the clipboard. The FilePath Controller only references the file location, not the content, so you need to handle the data capture manually. To fix this, configure a post-upload event like a data transform or activity to read the file from the specified path and convert it into a Base64 string for storage in pyAttachStream. You can use the FileListener or a custom activity to fetch the file content using the file path stored in the FilePath Controller. Also, ensure the correct security settings are applied, such as checking attachment type restrictions in the Application Rule and Dynamic System Settings (DSS). If you need to store the actual file data in the clipboard for further processing, consider using the File Upload control instead, which automatically captures the pyAttachStream. This approach ensures proper file handling and storage in your Pega application
