Could someone tell me the difference between SPDD & SPAU? I have used both but I am a little unclear as to the difference
HERE IS SOME DETAILS, GO THROUGH THIS.
SPAU and SPDD
When you apply a package, a large number of objects are changed.
If you have applied any OSS notes to objects in your system, the hot package may overwrite these objects.
SPDD is used to identify dictionary objects
SPAU (repository objects), will identify any objects where the hot package is overwriting changes you have made through OSS notes.
You must check all objects identified in SPAU and decide whether you need to reapply the OSS note or reset the code to the original SAP Code.
If, for instance, you are applying hot package 34, SPAU identifies an object where you have applied an OSS note. You must check the OSSs note and see if SAP have fixed that note in a hot package.
If the OSS note has been fixed in hot package 34, then you should reset the object to its original source code. This means that there is no repair flag set against this object again and it is now SAP standard code.
If, however, the object is not fixed until hot package 38, or there is no fix available you have to reapply the OSS note, otherwise users will encounter the problems they had before the note was applied.
You must transport all reapplied notes and Reset to SAP Standard objects after you apply your hot package to your QAS and PRD systems.
Preparing to Run Transaction SPDD
During the adjustment of ABAP Dictionary objects, the ABAP Workbench already has the new release (however, not the applications).
Setting the System Change Option
Before you begin adjustment, set the system change option for the SAP System to modifiable for all namespaces:
Start transaction SE03 as user DDIC and choose Administration ® Set system change option ® Global setting...
Select Modifiable in the Global setting dialog box.
Choose Edit ® Select all.
Save your entries.
Then log on as a normal user, since user DDIC may not perform any repairs.
Checking the User for the Upgrade
You must be able to log on to the system as user DDIC in client 000. In a new installed system, the initial password for user DDIC is 19920706. User DDIC must have the authorization SAP_ALL to be able to perform all operations during the upgrade.
If modification adjustment is required, log on in client 000 as the user who is designed to perform the adjustment in SPDD. This must be a different user than user DDIC. DDIC is not allowed to perform the modification adjustment.
If the profile SAP_NEW which contains the authorizations for the new release is available in your system, make sure it is assigned to the following users in addition to the existing profiles.
User who is to perform the modification adjustment with transaction SPDD
You perform the modification adjustment during the upgrade in a phase in which the system has an undefined state and the user maintenance transaction SU01 cannot be executed. To add a user, choose Tools ® Administration ® User Maintenance ® Users (SU01). You can also use the report UPGADDUSR provided you are authorized to create users. For the adjustment, UPGADDUSR creates the user upg_tmp_user with the password init in the client in which the report runs. The user is valid for one week.
If the profile SAP_NEW is not available in your system, we recommend that you temporarily assign the profile SAP_ALL to the user who is to perform the modification adjustment with transaction SPDD. Remove this assignment after the upgrade.
Activating Objects During Modification Adjustment
Save your work in the Dictionary maintenance transacton (SE11) but do not activate any objects. Activation is carried out automatically after the adjustment.
This does not apply if a Support Package is imported. Above all others, you must activate newly created objects.
Transaction SPAU: General Functions
Transaction SPAU allows you to process Repository objects needing adjustment. An overview shows all objects that have been modified by you, SAP, an IBU or an SAP partner.
For information on the selection of options on the selection screen in transaction SPAU, see Selection Screen of Transaction SPAU.
You can display modified objects in transaction SPAU by double-clicking them.
After you adjusted or edited an object, you can use the 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.
