A. 1. Check permissions: Go to your device's Settings > Apps > SAP Concur > Permissions and ensure that the app has permission to access your storage. 2. Use the camera function: Instead of attaching existing receipts, try using the camera function within the app to take a picture of the receipt directly.

B. 3. Ensure the receipt image is in a supported format: Check that the receipt image is in a compatible format (like JPEG or PNG) and not too large.
