• While upgrading to SAP ERP 6.18 SPS25 (or higher) using the Software Update Manager (SUM), an issue occurs during the build of the shadow system.
• SUM halts in the phase ACT_UPG (DDIC Activation), where several SAP standard tables fail to activate due to duplicate fields in the table structure within the shadow system.
• The SP upgrade encounters the following errors with the LIPS table:
