The SPAU activities can be done either immediately after SPDD activities or after the Upgrade of the system. Here also we have to choose between ‘Reset to Original’ or ‘Adapt Modification’.
Transaction SPAU is similar to SPDD but the objects involved here are the Repository objects (Programs, Function Modules, Screens, Interfaces, Documentation and text elements). Thus this is one of the most important steps in the upgrade project.Īfter the SPDD activities are completed, the system is then upgraded – the old version is replaced by the new version. Else, by choosing Reset to Original, the system will overwrite the customer changes and will reset the objects to the latest standard version. Basically if the customer has made any modifications to the objects in the old system and wants to retain it, he will choose Adapt Modification.
Here we have the option to choose the latest version of the object (Reset to Original) or to keep the changes made in the previous system (Adapt Modification). In SPDD, the system compares all the ABAP dictionary objects (data elements, database tables, structures) of the latest system with the old system. Transaction codes SPDD and SPAU are the core of an upgrade project. Stack levels of various patches – Basis, ABAP, XI etc should be brought up to the latest level since otherwise it may cause issues during the upgrade or Whereas in a functional upgrade, the functionalities offered by the new SAP version are also implemented in additionĪs the first step, the latest SAP version is installed on the hardware and all the general patches up to the latest stack level are applied. Technical Upgrade vs Functional Upgrade :Īs the name implies, technical upgrade only upgrades the software to the latest version and the new functionalities that come with the new version are Of course there are many secondary reasons, the significant one being the fact that like all software vendors SAP supports a released version of its software only for a limited period.
This is the major reason why companies should undertake a technical upgrade of their SAP system. Since technology and businesses evolve, companies need to maintain a technological infrastructure that can support that change. Tries to provide a functional overview about technical upgrade and also covers the evolution of SAP technical upgrade to Enhancement Packages concept. Most of the upgrade activities are done by the technical team and the role of functional consultants is limited and mostly confined to regression testing. SAP Technical Upgrade is a periodic project that is implemented across companies to upgrade their SAP system to the latest released version.
