Summary : 
      SAP Note addresses issues related to missing or outdated IGS executables within SAP systems operating on Basis 7.00 or 7.01 versions. To resolve this, users have two options: 1) Within systems featuring a Java stack, IGS updates can be applied via the Java Support Package Manager during the Support Package stack's definition or download, requiring a minimum JSPM version of 7.00.16.0.3 and IGS patch level 2. 2) Alternatively, patches can be manually implemented on any system type by downloading the IGSEXE.SAR package, ensuring proper execution of kernel-specific commands, and restarting the system post-update to maintain operational continuity.
