PAM
The Product Availability Matrix (PAM) is an online resource provided by SAP so that cus-
tomers can check the availability of a given SAP product and supported operating systems
and the databases. PAM can be accessed by using the SAP Portal URL: ht-
tps://service.sap.com/pam. PAM also provides vital information, such as the other software
dependencies and requirements, maintenance start and end dates, new product ramp-up re-
lease dates, and release-related OSS Notes. A Basis administrator uses this information to
install the correct SAP release so that it is fully supported and compliant with SAP standard
maintenance. Once the usage types and the product availability and release information are
gathered, the Basis administrator can proceed to start planning for the actual physical in-
stallation of the SAP software.
Significance of SAP Sizing
SAP sizing helps to estimate the hardware resources that would be needed to install the sys-
tem. Incorrect SAP sizing results in undersized systems that could affect the project imple-
mentation in terms of system growth, stability, and performance. SAP sizing should be done
starting in the design phase and continue even after go-live to plan for capacity planning of
the SAP system landscape. Usually, an initial SAP sizing effort is performed for budgeting
purposes, and subsequent sizing efforts help to estimate the long-term needs of the SAP
solution. Once the SAP sizing project is completed, the hardware vendor will provide re-
commendations. Since sizing is so important for the initial procurement of the hardware and
for on-going capacity planning purposes, a whole chapter ( Chapter 24 ) is devoted to study-
ing this area in detail.
