Hi

Technical upgrade is the fast upgrade without additional functionality but with minor user interface changes to ensure business continuity. In the past, all objects modified by a customer had to be manually re-modified during an upgrade. Now, modifications are either automatically adopted or the system provides you with an assistant for adjusting your modifications to the newly upgraded configuration using transactin SPAU and SPDD.

SPDD: This transaction allows you to adjust modifications to ABAP Dictionary objects during an upgarde.

Using this transaction we can adjust the Domains, Data Elements, Tables, Strcutures, Transparent tables, pooled and cluster tables including their technical settings, indexs of transparent tables. If you adjust data elements that have been changed with the Modification Assistant in an earlier release, the changes can be copied automatically.

Steps to run SPDD:

1. 1) Start transaction SE03 as user DDIC and choose Administration ® Set system change option

2. 2) Select Modifiable in the Global setting dialog box.

3. 3) Choose Continue.

4. 4) Choose Edit ® Select all.

5. 5) Save your changes.

6. Then log on as a normal user, since user DDIC may not perform any repairs.

SPAU: This transaction allows you to adjust programs, function modules, screens, interfaces, documentation and text elements after an upgrade.

After you adjusted or edited an object, you can use User/Status function to modify the status of the object. Before doing this, you can also add other developers or testers that are allowed to edit the object and create a short note.

Steps to run SPAU:

1) Start transaction SE03 as user DDIC and choose Tools ® Administration ® Set system change option.

2. 2) Select Modifiablein the Global setting dialog box.

3. 3) Choose Continue.

4. 4) Choose Edit ® Select all.

5. 5) Save your entries.

6. Then log on as a normal user, since user DDIC may not perform any repairs.

Other important topics in Technical Upgrade:

Updaring the Development System: Perform the adjust int he development system using SPDD and SPAU transctions and assign to transport requests. The upgrade control program R3up exports the transport that you have marked in a later upgrade phase.

Upgrading the Production System: During this phase, the R3up upgrade control program checks whether there are any change requests registered for transport from the development system to the production system. If this is the case, R3up offers to import the transport automatically, instead of you carrying out adjustments with transactions SPDD/SPAU. If you choose this procedure, you still have the option of stopping SPDD/SPAU to check the changes accepted automatically before they are activated.

If you decide to import a transport automatically, a subsequent analysis checks whether there is an entry in the transport you specified for each modified object found in this SAP System. Only if this is the case is the transport marked as suitable.

If there are more modified objects in the production system than in the test system, they cannot be dealt with by the transport. This means that you have to adjust these objects.

If you had more modified objects in the test system than in the production system and these are also contained in the transport, you import these into the production system with the transport
