Dear Guru,

Does SPDD and SPAU is one of the necessary step for the new SAP upgrading ?

We are going to upgrade SAPR3 4.7 to ECC 6.0 , and we have modified some standard sap abap program in our system .

If we upgrade the system without SPDD and SPAU , what happen when we upgrade the system to ECC6 ?

Does all the standard program will be replaced to the latest version ?

Many thanks .

Best Regards,

Hi,

Yes SPDD adn SPAU is a important step during Upgrade Project. Possibilities might be that some functinality may not work.

All the objects which are modified, after tansporting to the current system, will be listed in SPAU and SPDD. SPDD contains the list of all modified Data Dictionary objects, like tables, data elements, domains,view...etc. The rest of all the modified repository objects will be listed in SPAU (reports, function modules etc.)

When you apply a SP package/Uprgade, a large number of objects are changed in SAP system. SPDD is used to identify dictionary objects and SPAU (repository objects) identify any objects where the hot package is overwriting changes you have made through OSS notes. You must check all objects identified in SPDD/SPAU and decide whether you need to reapply the OSS note or reset the code to the original SAP Code. Changes to SPDD are very important and shoud be carried out with care as for SPDD you need to make decision there and SPAU information will be downloaded and given to ABAPers to work on. If you dont carry out SPAU and SPDD you will loose the modification you have made to any report or table, view data element.

yes , that is one of necessary step during the upgrade !

SAP will use the latest version, that would be the version from ECC 6 or its latest support pack. This is usually OK, but not always, this is why SPAU and SPDD must be revised BEFORE bringing upgraded system to productive state.

Hi,

If you will not perform SPDD and SPAU in the upgrade then you will loose all your data related to the objects that will come in SPDD and SPAU. Also, might be some of your functionality will not work. So, performing SPDD and SPAU is very important in upgrade project.

Thanks
