Tuning SAP does always need a considerable range of observation before prescribing or implementing anything on the system. It needs a considerable amount of patience to listen to the existing tech team, users and over and above all some managers ( bunch of jokers – never do things right – habitually only manage the scenario). Besides one also need to listen what system monitoring transactions, system logs, debugging utilities etc are screaming…..

To start with we do need to come across a questionnaire, which must carry some of the following questions…..

  • When you are experiencing system is slow? during a transaction or during execution of a report or a transaction associated with a report for generating some online documents? – User
  • When you are experiencing a slow response? During using of SAP standard Tcodes and Programs or the customised (Z) Tcodes and programs? – User
  • What are the available downtime? – Service Level Management
  • What is your storage architecture? – Release Management…
  • Are you using some kind of middle-ware product, which provide only complied version of their library routines? – Release Management
  • What are the sampling rate of error messages? Do you have some ready made history documents of such ready in hand? – Basis and Functional consultants.
  • What is the standard network response between Application level and Presentation level? Basis administrators.
  • What are the known issues (pardon I am not using the many-referenced phrase known error) with the hardware you are using, with storage, with the OS, with the middle-ware, Oracle database version and obviously the release and versions of SAP itself you are using? – system administrator, storage administrator, database administrator, basis administrator and the fact sheets, notes, whitepapers from the respective vendors. Many already argued on this thought of mine, saying that this particular set of documents can bias the investigation and then the remedy but believe me it is always better to have these documents in hand. Otherwise the whole thing may end up in chasing wild goose. Remember whether OEM support is there or not may bother you heavily when you are going to implement some solution….oh yes even tuning solution…..
  • Do you have an ABAP program benchmarking existing for the customised ABAP programs? If yes then check the relevancy of the same with the data growth rate (yes this is very important) else you make your own. I have something of my own and will be sharing here.

These are some basic things one should gather to undertake a tuning job for SAP. Otherwise, one’s  may land up with some tuning suggestion which is impractical or not cost effective. In the whole series of these shareable document, I tried to restrict the suggestions which do not involve additional costing.
