The program tp offers several advantages over direct use of the programs it uses:
· tp helps keep track of transports.
· tp exports and imports objects in the correct order.
· tp ensures that imports into a target system are done in the same order as the exports from the source system(s). Processing imports out of order can result in severe inconsistencies in the target system.
· These are hard to diagnose. tp lets you perform exports and imports separately.
During an export, the objects to be transported are extracted from the database of the source system and stored in files of the operating system.
In the import phase, the objects are added to the database of the target system (according to the transport function recorded in the task).
An export should always take place immediately after the change request has been released, so that the objects can be freed for further modification.
An import often cannot be performed immediately. To maintain performance, stability, and avoid conflicts with the online SAP System, perform the import at night (see also Planning Imports).
tp is currently available for the following operating and database systems:
· Operating systems: UNIX, Windows, IBM eServer iSeries
· Database systems: Oracle, Informix, MaxDB, Microsoft SQL-Server, DB2 UDB for iSeries, DB2 UDB for Unix and Windows, DB2 UDB for OS/390
tp supports a transport network between UNIX and Windows systems. For more information, see Transport Control under Windows.
