3756483 - Cannot Set Billing Document Custom Field to Read-Only in SAP S/4HANA Cloud Public Edition

A custom field added to the Billing process cannot be configured as non-editable (read-only) in app 'Change Billing Documents'(VF02).

SAP S/4HANA Cloud Public Edition

1. Create a custom field using the Custom Fields (F1481) app.
2. Publish the custom field and enable it for Billing Documents.
3. Open a Billing Document via the Manage Billing Documents (F0797) app where the custom field is available.
4. Observe that there is no option available to make the custom field read-only.

Handling or setting custom field properties (e.g. make it read only) for Billing Documents is currently not supported. 

• The current product limitation is that making a Billing Document custom field read-only is not supported at this time. As a workaround, the custom field can be hidden from the Billing Document UI while still allowing the value to be copied automatically from preceding documents for storage and printing purposes.
• Kindly upvote the enhancement request already submitted in the Improvement Request Details - Customer Influence BADI for modification of customer field in invoice document) to help prioritize this functionality.
