1301301 - Release Strategy for SAP Best Practices Package ABAP Add-ons
1644833 - Vendor keys for SAP Best Practice add-ons
From note 1644833:
- During upgrade of your system using SAPEhpi/SUM/SAPup, the
tool asks for a 'decision' in IS_SELECT phase.
- Technically SAP provides a so called "Vendor Key" for SAP
upgrade/update of systems. This is only to ensure that the
upgrade is technically completed.
- When SAP EhPI/SAPup/SUM asks for a decision regarding
installed add-ons, choose "KEEP" for the SAP BP add-ons. In
the next step a vendor key has to be provided.
