Difference between Support Pack and Patch in SAP PI

 Support Pack vs Patch 

What is the difference between support pack and patch in SAP PI?


Support Package Stack

  • A Support Package Stack (SP) is a collection of bug fixes and feature modifications.
  • Each Support Package has a collection of all the Software Components which make up the PI system.
  • New Support Package (SP) is released quarterly (this may change depending on the PI release).
  • All the components of the PI system should always be on the same SP release due to software dependencies.

Support Pack vs Patch in SAP PI


  • A Patch contains fixes for an individual Software Component, which belongs to a specific SP release.
  • Several Java-based Software Components exist which are relevant to the PI system.
  • Many fixes are released by SAP in the form of a patch, for each of the PI Software Components on regular basis.
  • These fixes are released on a weekly basis depending on the PI release, the SP release and the specific Software Component.
  • Please go through SAP document 1381878 in order to check the Patch Levels (PL) of the individual PI Software Components.
  • Each Java patch for the PI SC's contain all previous patches e.g. the XIESR SP06 PL14 contains PL14, PL13, PL12 etc.
  • Also, individual PI Software Components contains many dependencies (SAP document 1381878).
