3787503 - supplier confirmation attachments: "no document type found" when uploading

Supplier confirmation attachments cannot be uploaded; error: "No document type found. Either you do not have authorization for any document types or none have been configured. Failed to upload attachment".

• Product: SAP S/4HANA Cloud Public Edition 2608CE
• Supplier Confirmation on S/4HANA (Public Cloud)

1. Open the Manage Supplier Confirmations app.
2. Select a purchase order.
3. Create a supplier confirmation.
4. Attempt to upload an attachment.
5. The error appears: "No document type found. Either you do not have authorization for any document types or none have been configured. Failed to upload attachment".

The feature depends on reference content that was not yet imported (CBC/content upgrade pending in 3-system landscape), so the HDM attachment object type for supplier confirmations was not available/configured, resulting in no document type being found.

You can find the details on dependency in Whats New 

1. Verify whether the latest reference content (CBC content upgrade) has been imported into the test system. If not, wait until the content upgrade is completed; new features that require the latest content cannot be tested beforehand.
2. After the content upgrade, open SSCUI 105346 “Activate HDM for Attachment Object Type”.
3. Activate the attachment object type for supplier confirmations and enable document type SL1.
4. Save the configuration (and transport if applicable).
5. Retest in Manage Supplier Confirmations by creating a supplier confirmation and uploading an attachment.
