just came back from our summer meeting of the DSAG data archiving work group and want spread some news.

The HANA hype has hit our company too and while the marketing material reads nice you always stuck when it comes to a detailed question for such a new product.

Today HANA and data archiving was one topic among others, but it was THE topic that got me actually to the DSAG meeting as we had heard some rumors that there will be no data archiving with HANA and wanted some clarification. Further we had no clear picture about Hot and cold storage. Actually we know this term well from our logistic processes in the chemical industry but had some confusion how it is done in SAP.

Hot and cold storage are actually partitions in a database, which is much different to data archiving where you have productive data and archived data usually in 2 different databases

It was said by SAP represenatives:

  • SARA will still be around with HANA Business Suite and S/4HANA, because there will be many business objects around that are not changed and will be archived with SARA transaction as it is today



  • HANA Business Suite will use Data Aging to move older data from the Hot partition to the cold partition in the same database for all changed processes like sFIN (Simple Finance)

  • HANA Business Suite comes with data aging content for SFin, Idoc, Application log, Status management (table JEST)

  • No plans to add further data aging objects to the HANA Business Suite


 

 

  • S/4HANA will use Data Aging instead of data archiving for all changed processes

  • Beside of the objects that are mentioned for the HANA Business Suite SAP is working on data aging objects for material documents, purchasing documents, production orders (the core part of Simple Logistics)

  • There is currently no data archiving for the objects which are covered by data aging, for example the BSEG data from Financial document will stay in S/4HANA and cannot be archived until SAP has developed new archiving programs. They are in the early phase of evaluating options and think that it will need some years to a final solution.


 

 

  • You can always access the data which was archived before you upgraded to S/4HANA.

  • There are no plans to dispose the SARA transaction


 

 

 

I hope this will clear some doubts that you probably had in common with us
