3608788 - How to add an attachment directly after creating a billing document

How to upload an attachment and merge with output items without automatically posting the invoice directly?

SAP S/4HANA Cloud Public Edition

This setting can be done from the user end in the "Create Billing Documents" app. If the invoice is directly posted, all output items will be sent immediately, preventing attachments from being merged. By blocking posting during creation, attachments can be added and merged, and the posting action can be triggered afterward. This ensures the status of output items is updated after adding and merging the attachment.
