You have selected an SAP Support Package Stack on SAP Service Marketplace at service.sap.com/sp-stacks. On the last screen, where you have to add the list with the corresponding files to your download basket, you have an option to choose Save As File. You can download the list as an CSV file for a spreadsheet or as an XML file. What is the benefit of the XML file and how can you use this file?
The XML file contains a description of the Support Package Stacks. It is an individual file, which contains the selection (OS and DB) you have made. Therefore, you can use this XML file only for your individual installation.
The XML file will be read by the Java Support Package Manager (JSPM), which is available as of SAP NetWeaver 2004s. This XML file allows JSPM to deploy a consistent Support Package Stack to your system without any additional input.
In step 3 of the SP-stack wizard select the button 'Save As File', right-click on the XML-file entry and save the file in your global EPS Inbox directory /usr/sap/trans/EPS/in.
For a step-by-step description of the update procedure, see respective Support Package Stack Guide.
