SAP R/3 Transport Management System (TMS), Transport Tools

Transport Tools

There are two executable programs, R3trans and tp, residing at Kernel level runs for a TR to be exported and imported.This tool R3trans does the complete transport work for tp which can be used for transporting data between different sap systems, even when they don’t belong to the same group. R3trans normally is not used directly but called from the transport control program, tp. It is the basic tool for the transporting the request. Where in R3trans.exe which obtains connection to the database TP controls the transports and generates the R3trans control files in tmp directory, but does no database-connect itself. All the “real work” is done from r3trans. So that R3trans reads the control file of TR and update the entries in to TRBAT and TRJOB tables. Then related programs, RDD*, started using background wp reads these table according to that imports the data form data file in to database of target system.

Common Transport directory

Usr/sap/trans of TDC residing at OS level of central instance, is called as common transport directory for all the systems taken place in the TD. Once a TR gets released accordingly there are two files get created in data and cofile folders of common transport directory and that TR number gets entered in to the target system buffer folder.

  • /Data: All transport requests data file gets stored in this, which are in the format of R<T.RNo>.<SID>
  • /Cofile: All transport requests control file gets stored in this, which are in the format of K<T.RNo>.<SID>
  • /bin: where Domain.cfg and transport profile which is tp_Domain_<Sid>.Pfl gets stored
  • /Log: Where all the TR logs get stored which are two types
    • -Slog: Which called as status log maintains steps were performed by TR.
    • -Alog: This is nothing but Action log maintains log information of every step like execution of reports, generation….etc in detail with the information of object list of TR.

Note: As per return codes

  • RC 0→successfully completed
  • RC 4→ended with warnings
  • RC 8→ Ended with errors (should be reported to ABAPers)
  • RC 12 & above→ended with errors (taken care by Basis admin).

/Buffer: Which maintains all the transport request information have to be added in to import queue of other systems connected in transport domain. Unless a TR added in to buffer which can not be imported in to target system..

/Sap Names: Maintains all the user ids of users who creates a TR and its list in that system

/Tmp: Called as temporary directory or temporary folder where support pack released logs get created.

Importing Transport request

As per two types of TR, generally which are local and remote, scc1 is to import the TR between different clients of same database where it was created. Remote TR consists two steps to move from one to another system, which are export and Import.


Once a TR released as per the target mentioned to TR automatically gets added in to that target system import queue, If transport routes have been configured which is called as Export. Import:

STMS Configuration

take dev server as TDC login in to dev server with 000 and ddic user hit se06 to perform this post installation activity hit stms


give system name,description and transort domain details and save
