Support Package & Stack Upgrade: SAP SPS

What is a Support Package?

• When an end user of SAP finds a bug in the SAP product, he reports the same to SAP support. SAP programmers inspect the bug and develop a correction for the bug. This correction is known as SNOTE (SAP Note).
• With time, multiple end users, report bugs for which SAP releases SNOTE. SAP collects all these corrections in one place and this collection is called SUPPORT PACKAGE. This support package also includes enhancements to earlier versions of SAP.
• In simple words collection of SAP NOTES is called as SUPPORT PACKAGE.
• Support Packages are implemented in SAP system using Transaction SPAM (Support Package Manager)

What is Support Package Stack (SPS)?

The Support Package Stack is a list of ABAP and Java Support Packages for all software components (SC) included in SAP NetWeaver. It is used to bring each Software Component of SAP NetWeaver to a defined Support Pack (SP) level.

Support Package Stack, commonly known as STACK bundles all required components or individual patches that are already tested together and recommended applying as SPS instead of individual patch (until and unless you face some problem which requires certain components to be patched).

Go to https://service.sap.com/sp-stacks/, select your NW version to check the current SPS level and other details.
 

What are Support Pack Stack version numbers?

Support Package Stacks have a release number, and a Stack number, Example, SAP NetWeaver '04 Support Package Stack 11.

Each software component has a separate sequence of Support Packages. The following list contains the technical names of a number of components and the notation for their Support Packages:

• COP (Component Package):
• SAP_APPL (SAP APPL Support Package): SAPKH<rel><no>
• SAP_BASIS (Basis Support Package): SAPKB<rel><no>
• SAP_ABA (Application Basis SP): SAPKA<rel><no>
• SAP_HR (SAP HR Support Package): SAPKE<rel><no>
• SAP_SCM (SCM Support Package): SAPKY<rel><no>
• SAP_BW (BW Support Package): SAPKW<rel><no>
• SAP_CRM (CRM Support Package): SAPKU<rel><no>

 Pre-requisites for Support Package implementation:

• Support packages should be always applied in client 000.
• The user to be used for the support package implementation must have authorizations equivalent to DDIC or SAP*
• Call the transaction SPAM and see if any previous Support Package import is incomplete. You can proceed ahead unless the previous support package import is successful.
• Ensure that there is enough space in the transport directory. The transport directory is located at /usr/sap/trans

Steps to Upgrade the Support Package:

Step 1: Download Support Packs

Support Packages are available in SAP Support Portal, under service.sap.com/patches.
  Step 2: Loading Support Packages:

To load support packages we have two options:-

1. From Application Server
2. From Front End

From Application Server

1. Download the support packages from service marketplace and save them at OS level in directory /usr/sap/trans.
2. Uncompress these files using sapcar executable

sapcar –xvf <support package name>

After uncompressing the support packages at OS level the .PAT and .ATT files are stored in /usr/sap/trans/EPS/in directory.

Next, load the Support Packages into SAP system by choosing  Support Package -->Load Package  --> From Application Server
  From Front End

Choose Support Package --> Load Packages --> From Front End
  Step 3: SPAM/SAINT Update:

A SPAM/SAINT Update contains updates and improvements to Support Package Manager (SPAM) and Add-On Installation Tool (SAINT). There is always one SPAM update for each release. SPAM/SAINT update is mandatory before any support package upgrade.
  Step 4: Defining Queue

Queue contains the Support Packages available for the different SAP Components installed in your system. This Queue information is derived from the support pack uploaded in Step 2.

1.On the initial screen in Support Package Manager, choose Display/Define.
2.A list of installed software components (for example, SAP_BASIS, SAP_HR, SAP_BW) is displayed. 3.Once you select the required component, the current queue appears. This queue contains the Support Packages available for the selected component in your system. If you want to define the queue for another software component, choose Other Component. If the displayed queue meets your requirements, you can confirm it by choosing Confirm Queue
 

Step 5: Importing Queue.

Once you a define a Queue (Step 4) while selecting a particular component (for which we want to upgrade support pack), we need to do 'Import queue' to start importing/applying that particular selected support pack (as per the standard SAP process).

Choose Support Package --> Import Queue
