ECC upgrade impact on data archival

Friends,

We are working on the data archival SAP version 4.7, parallely ECC upgrades activities are going on. We are working on the archive tools like transactions SARA, SARI etc as part of archiving. Not sure on what changes to the features will be available in the ECC6.0 version and its impact on already archived files. Can somebody give some inputs/direction?

thanks

Nalinikanth.

    Hi,

    This is a very nice question.

    Generally, we can do archiving in this case in two available options:

    1. Archive before upgrade

    2. Archiving during upgrade.

    Yours is the second case. There will be no impact on upgrade process only when we are archiving the historical data say SAP data of age 2 yrs or so.

    Yes, there ll be an impact on the archived data on the upgraded SAP version when you want to reload or restore the archived data back to SAP.

    Since, at the time of archiving, SAP version is 4.7 and when you move to 6.0 and want to restore archived data into SAP system ECC 6.0..then there willl be a lot of inconsistencies in the data present the SAP tables. In this case, Reload is NOT recommended.

    Thanks,

    Shamim

    Hi,

    Retrieval of Archived data

    1. SAP system support to retrieve data archived from 4.7 system by ECC system. There is no negative impact in retrieving archived data of deferent version in ECC system.

    Advice to take back ups of Field catalog, Archive infostructure in case it is Custom or any additional field added to standard structure.

    2. Some changes in Archive index is there in ECC system -

    In ECC system, if you want to retrieve archived data from FB03 then activate and fill the Archive infostructure, Archive build index will not work.

    This method remains same for Material document and other documents

    In ECC system SAP recommends to use Archive system instead of building archive index table such as ARIX_BKPF...

    Archive Program

    1. All the BC sets to upgrade archiving process are been implemented in ECC system, so you can see some changes in the Write program, Delete program.. or for some archiving object you may also see addition of preprocessing program..

    For example: MM_EKKO in initial released 4.7 version didn't had preprocessing job, Write job variant had option of company code to archive purchase order. Later BC set was released with upgraded programs with Preprocessing program and in Write variant with selection of Purchase organization instead of Company code.

    If you have already implemented latest release of BC sets then in ECC 6.0 will not have any changes otherwise some minor changes you can see.

    Please specify which archiving object with program you are concern with.

    Store Function

    1. In ECC system, SAP has filled up a long standing gap of storing archived data of different company code in separate content repository. This is very much useful when you want to store the archived data of different organization units in different storage repository. This also easy to get rid of data that has completed total retention period from the storage system.

    Remain other functionality remains the same. Please let me know if you have any concern about archiving object that you are using.

    -Thanks,

    Ajay
