Sometimes, there will be situations like you have to process transport imports manually. This can be done by TP program from the operating system level.
Transport control program TP is controlled by a parameter file TP_<domain>.PFL which is present under bin subdirectory of the transport directory.
Please note in older releases of SAP R/3, the file is termed as TPPARAM.
Before using TP for the first time, it is suggested to test the connection to the desired target system.
To perform this test, following command can be used.
tp connect <target system> pf=<complete path of the parameter file>
If this test results are fine you can proceed further otherwise you need to troubleshoot the same and identify the reason for the same.
In order to insert a request into the import queue of an SAP R/3 system, use the following command:
tp addtobuffer <request> <target system> pf=<complete path of the parameter file>
If the above command is successful then, datafile and cofile of the request will get copied under respective data subdirectory and cofiles subdirectory of the transport directory.
As the request is inserted to the import queue, it can now be imported using the following command.
tp import <request> <target system> pf=<complete path of the parameter file>
In case you would like to import all the requests that are present in the import queue of an SAP system in the current sequence then provide the following command at oslevel.
tp import all <target system> pf=<complete path of the parameter file>
You can add the following to specify a specific client for import:
client = <number of the client>
If the client is not mentioned, the data is copied to the client with the same number as the client from which the data was exported.
If the client into which you would like to import a request does not exist in the target system, the import terminates with an error message.
