You want to preview the header attachment in Create PR/PO - Advanced app before saving, but the option Attachment List is greyed out.
SAP S/4HANA Cloud
Reproducing the Issue
- Access the Create PR Advanced app or Create PO advanced app
- Click on Services for Objects
- Create Attachment
- Upload a file from your PC
- The attachment list option is still greyed out
Standard system behavior.
There is no way to preview the attachment in the Advanced apps, the Advanced apps upload the attachments via GOS (Generic Object Services) so the attachment will be fully uploaded to the SAP system when you save the PR or PO, then the Attachment list option will be available.
