Programs that Are Independent of the Database
Software Version 
Programs that are independent of the database software version are only installed once for each computer, since they are needed for the database services that exist for each computer.
SAP DB Directories
The programs that are independent of the database software version are stored in the IndepProgPath directory: <independent_program_path>.
In this directory and its subdirectories, you will always find the programs for the most recently installed version of the database software.
