Summary :
Despite the restriction to user-specific display variants in Transaction VF04 (Process Billing Due List), users are able to modify standard display variants due to a parameter oversight. This issue stems from the omission of a critical parameter transfer, identified in Note 217156, to the function module. To rectify this in SAP Release 4.7, firstly implement Note 217156. Subsequently, enhance function module VKDFS_ALV_DISPLAY in SE37 with an import parameter (I_SAVE) set to 'A'. Lastly, apply the provided correction instructions to enforce the appropriate authorization checks for display variant maintenance.
