3806569 - Functional Area field blank and not editable in PO-based supplier invoice; value derived at posting — SAP S/4HANA Cloud Public Edition

• In the Create Supplier Invoice app, when referencing a Purchase Order with Cost Center account assignment, the Functional Area field is blank and cannot be edited.
• On simulate or post, the system derives a Functional Area from the Profitability Segment in the resulting Journal Entry based on the account assignment.
• No error message is shown.

• Product: SAP S/4HANA Cloud Public Edition
• Fiori UI for Invoice Verification (Public Cloud)

1. Open the Create Supplier Invoice app (PO-based).
2. Reference a Purchase Order that uses Cost Center account assignment.
3. Navigate to the Functional Area field on the Supplier Invoice screen and observe it is blank and not editable.
4. Click Simulate or Post and observe that the Journal Entry derives the Functional Area from the Profitability Segment.

• Functional Area is a finance/controlling attribute, not a purchasing attribute on the PO line.
• For PO-based invoices with Cost Center account assignment, the Functional Area field is display-only and therefore locked on the invoice UI.
• At posting time, the system derives the Functional Area automatically from the Cost Center master record; if that is blank, it is derived from the G/L account record. This is standard, intended behavior.

1. Note that manual entry of Functional Area on PO-based invoice lines with Cost Center account assignment is not supported by design.
2. Maintain the required Functional Area on the relevant Cost Center in the Manage Cost Centers (New Version) app so future postings to that Cost Center derive the correct value.
3. Post or simulate the invoice to allow the system to derive the Functional Area automatically.
4. Verify the recorded Functional Area in the resulting accounting document using Manage Journal Entries (New Version).
5. If per-invoice manual entry is a strict requirement, submit a product enhancement request via Customer Influence (refer to the note below).
