If you want to installtp, the operating system users must fulfill the following requirements.
Operating System Users - UNIX
Operating system tools are used to check the authorizations for the files in the transport directory. To transport in a group of systems connected for the purpose of transport,tp gives the group belonging to the owner of a file all authorizations for that file. Group sapsys, containing all the owners of the SAP Systems (<sapsid>adm), plays a central role here.
Operating System Users - Windows
Each user that wants to use the transport system requires read and write authorization in the transport directory.
If you call a transport program directly from the operating system level, only use the operating system user<SAPSID> ADM.
If you call a transport program from the SAP System (Change and Transport Organizer or Transport Management System), the user under which the SAP System was started is used. This user isSAPService<SAPSID> for a standard installation of the operating system user.
To check which user started the SAP System, choose My Computer ® Right-click ® Manage ® Services and Applications ® Services ® SAP<SAPSID>_<Sysno.> ® Log on As.
For each SAP System that is part of the transport group, you must give read and write authorization to the following operating system users:
<SAPSID> ADM(for example, C11ADM)
SAPService<SAPSID>(for example, SAPServiceC11)
Operating System Users – IBM eServer iSeries
Each user who wants to use the transport system at operating system level must be a group member in the group profile<sapsid>OFR.
This gives the user authorization to call transport programs. The programs themselves inherit the rights of user<sapsid>OWNER.
Note that at present user names and passwords must be exactly the same in all SAP systems. This is a restriction required for remote access using
