SAP-Technical Upgrade (EhP)

SAP-Technical Upgrade(EhP)

There are six steps to perform SAP Technical upgrade :-

1. System Preparation :stack level of various patches like BASIS,ABAP,XI should be up to the latest level.
2. SPDD Phase : System compares all the ABAP dictionary objects(eg-Data Elements,Data tables,Structure) of the latest system with the old one.

(If customer made any changes to the objects in the old systems and wants to retain,choose "Adapt Modification",else choose"Reset to original".

3. Upgrade of the System:After the SPDD activities are completed, the system is then upgraded - the old version is replaced by the new version

4.SPAU Phase : Transaction SPAU is similar to SPDD but the objects involved here are the Repository objects (Programs, Function Modules, Screens, Interfaces, Documentation and text elements). Here also we have to choose between ‘Reset to Original’ or ‘Adapt Modification’. The SPAU activities can be done either immediately after SPDD activities or after the Upgrade of the system.

5.Testing :- Typical issues encountered during testing are short dumps, performance issues, variants for reports missing, not printing the smart forms correctly, etc.

Z- Programs :The number and size of custom modifications in the system determines the complexity of the upgrade project. Because many of the function modules and dictionary elements might have become obsolete and replaced by newer ones, the Z programs using the old functional modules and dictionary elements will not function correctly in the new system.

6. Post upgrade activities :Some activities have to be executed manually in each system after upgrade since they cannot be included in a Transport Request. Eg. Regenerating ABAP queries after upgrade.
