Based on some conditions, I managed to put some fields in display mode in tcode ME52N by inserting an implicit enhancement in Include lMEREQF05, method GET_FIELDSELECTION and changed CH_FIELDSELECTION for all fields of Account with field status '*'
This change is reflected in GUI but not in FIORI App(Purchase Requisition profesional F2229). In GUI all account fields are in display mode but in FIORI they are editable.
I want the same behavior also in Fiori App. Is there a way to put all account fields in display mode also for Fiori app?
