3793762 - Cannot change "Reference Key 2" on noted item in Manage Journal Entries after Posting in S/4HANA Cloud Public Edition

Symptom

The 'Reference Key 2' field in a noted item journal entry cannot be changed after the document is created/posted using the app Manage Journal Entries.
The configuration activity 'Define Journal Entry Change Rules' does not offer 'Reference Key 2' for selection, so the field cannot be opened for changes.
The clearing process requires an update to 'Reference Key 2', but the field remains non-editable.

Environment

SAP S/4HANA Cloud Public Edition

Reproducing the Issue

Open the app Manage Journal Entries and select the noted item journal entry.
Attempt to edit the line item field "Reference Key 2".
Observe that the field cannot be selected/changed and is not available via 'Define Journal Entry Change Rules'.

Cause

'Reference Key 2' at line-item level is not available in SSCUI/CBC activity 'Define Journal Entry Change Rules' (SSCUI 104309.
Therefore it cannot be changed after posting via document change rules or the change API.

Resolution

If the clearing process depends on this value, the recommended approach is to populate the required reference during the creation of the noted item or payment request, rather than attempting to update it afterward.
Use the Payment Reference field and there is no standard warning regarding the use of Payment Reference. As long as the clearing process, matching rules and any dependent custom developments are designed to use Payment Reference, this approach is supported.
