Preparation for SAP upgrade or support package

Support package

This blog explains about preparation you can do for SAP upgrade of support package.

Questions that will be answered are:

  • Where to find support package schedule?
  • Where to find version information on upgrades?
  • Do I need to do delta sizing for upgrade?

Latest availabale main version for upgrade

For the latest available version you can check the SAP product availability matrix site. This is also know as the SAP-PAM.

After finding the right product on the first tab you can see the current release details and end of support date.

PAM details release and support dates

On the second tab you see the upgrade paths that are supported:

In the middle the target version. On the left hand the versions from which you can upgrade. To the right are even higher versions you can upgrade to.

Latest available versions of support packages

The latest availabe versions of support packages are published by SAP on the SAP support package stacks page. On this page click on the SAP support package stack maintenance schedule link to download the latest version of the schedule.

Support package version: minus one or latest?

In many companies there is a policy to never take the latest version of a support package. The line of thinking is: let other people solve the bugs of SAP first.

Current delivery of ABAP support packages is quite good. And the frequency is not so high as in the past. For ECC about 2 to 3 support packages per year are released (as compare to 6 to 9 in the past in the 4.6 ages).

In stead of taking minus one, you can also consider this rule: at point of go-live make sure that the support package is at least released 3 months ago. This will counter the risk of having an issue which is not discovered by anyone else before.

Delta sizing

Delta sizing for support packages is not needed. Delta sizing for an upgrade might be required if:

  • Upgrade crosses multiple versions (for example upgrade from Netweaver 6.20 to Netweaver 7.51)
  • Upgrade is including a new database (for example migration to HANA database)
  • Specific upgrade manual is specific about delta sizing (for example the upgrade from SAP solution manager 7.1 to 7.2 is specific enough to carry out delta sizing)

Custom code

For analyzing custom code before the upgrade you can use the CDMC toolset. For more information read this blog.

Releasing transports and cleaning up transport pipeline

For both support package and upgrade releasing transports is a technical must. It is wise to start a few months before already cleaning up the transport pipeline (transports that are old and not released in development system, transports that are imported into quality environment, but no imported in productive system).

Side effect report for support packages

Per support package SAP keeps track of the unwanted side effects. OSS note 2388572 explains you how to retrieve them for your support package. Best to scan the side effects and apply the ones you think are needed.

For upgrades the side effects list is too large: here you simply need to test and fix any issues encountered.

New functions

After the upgrade you can start to use new functions. Some main functions are listed in the SAP help pages. The more unkown small features are listed by SAP in the SAP improvements finder xls. This xls has 2 tabs: first with the most recent and second with the long list of improvements since 2014. Per improvement you need to check pre-conditions of release and support package, but if you upgraded to recent version, most of the improvements will be installed. Some improvements are always active, some need extra activation steps. This is documented per improvement item.
