An important tp parameter is the name of the SAP System tp needs to log on to. This is not a parameter that can be set in the transport profile. You set it implicitly by making entries in the command line when tp is called. The name of the SAP System is included as one of the arguments in the command line, or it can be determined from the first three characters of the change request specified (for export calls).
Possible values: Text
You can define a list of up to 50 SAP Systems with this parameter. The names must be separated by commas. If the export of a change request is successful, tp determines the test systems that have been specified for the target system of the change request and places the request in the buffers of these test systems.
