Setting Up TMS and CTS, and Maintaining Clients As of R/3 Release 4.0, system landscapes are defined in terms of transport domains. Development objects and Customizing settings are distributed through the transport system between all R/3 Systems configured within the same transport domain. Each R/3 System in the domain requires a unique ID. Systems within a transport domain that use a common transport directory comprise the same transport group. Configuration and administration are first performed on one R/3 System, known as the Transport Domain Controller. This R/3 System then provides the reference configuration that is distributed to the other R/3 Systems by Remote Function Call (RFC).
Setting up the transport domain and transport group defines the physical transport environment. Transport relationships, that is, the roles of the R/3 Systems and the direction for transporting change requests, are defined through transport routes. In each R/3 System there are also a number of clients, each of which is designed to play a specific role.
To set up the TMS and the CTS, the system administrator requires the authorizations S_CTS_TR_ALL and S_CTS_ADMIN (profile S_A.SYSTEM). User DDIC configures the clients.

How to Perform Tasks
Performing Installation Follow-Up Work Installation follow-up work generates the basic settings of the Change and Transport Organizer (CTO).
1. Log on to the Transport Domain Controller using client 000 and user DDIC 2. Choose Tools Administration Transports Installation follow-up work.
The screen Processing after Installation for CTO is displayed. 3. Select either R/3 Standard Installation or Database copy or migration, as appropriate. 4. Choose Installation CTO post-processing Execute. 5. Choose Back.
Configuring the Transport Domain Controller and Transport Domains To use the transport system, first define a transport domain. The R/3 Systems in the domain require unique names. Choose an R/3 System with high availability and security to be the Transport Domain Controller. All administrative activities for the Transport Management System (TMS) that affect the entire transport domain can only be performed in the Transport Domain Controller. By setting up the TMS, you automatically set up the CPIC users TMSADM and TMSSUP, generate the required RFC destinations, and record the TMS configuration in the transport directory (file DOMAIN_DEV). The Transport Domain Controller has the reference configuration, which is distributed by RFC to all other R/3 Systems in your system landscape.

1. Log on to the Transport Domain Controller as the system administrator using Client 000. 2. Choose Tools Administration Transports Transport Management System (or use Transaction STMS).
The screen Transport Management System is displayed. 3. Enter the name of the transport domain and a short descriptive text. 4. If your R/3 System consists of several application servers, you can select a server. 5. Choose Save.
Applying to be Included in the Transport Domain After configuring the transport domain on the Domain Controller, all other R/3 Systems in your system landscape must apply to be included in the transport domain. This means that on those R/3 Systems the user TMSADM is created, the required RFC destinations generated, and the addressees sent to the Domain Controller. To apply to be included in the transport domain, execute the following steps on each R/3 System in your system landscape except the Domain Controller:
1. Log on to the R/3 system as system administrator using client 000. 2. Choose Tools Administration Transports Transport Management System (or use Transaction STMS).
The screen Transport Management System is displayed. 3. If there is a common transport directory for all R/3 Systems in the transport domain, your current R/3 System is automatically proposed as the one to be included in the domain.
The dialog box TMS: Include System in Transport Domain is displayed. 4. If your R/3 System consists of several application servers, you can select a server to be included in the domain. 5. Choose Save.
Confirming Inclusion in the Transport Domain For security reasons, each R/3 System newly included in the transport domain must be confirmed in the Domain Controller as follows:
1. Log on to the Domain Controller as the system administrator using client 000. 2. Choose Tools Administration Transports Transport Management System (or use Transaction STMS).
The screen Transport Management System is displayed. 3. Choose Overview Systems.
The screen System Overview: Domain

8. To distribute the configuration , choose Extras Distribute TMS configuration. 9. After all R/3 Systems have been included in the transport domain, document the configuration in the table Transport Domain and Systems in the section on Configuration. This documentation enables you to subsequently compare current configurations in case of problems.
Creating a Transport Directory All R/3 Systems that access a common transport directory form part of the same transport group. The configuration is recorded in the file GROUP_DEV on operating system level. Create the transport directory directly after installation as follows:
1. Create the transport directory on operating system level, on one of the systems in the transport group:
Adapting TPPARAM The file TPPARAM is the global parameter file for the transport control program tp, and must be adapted after every new installation as follows:
1. In the development system, on operating system level go to the transport directory

Defining Transport Routes Transport relationships, that is, the roles of the systems and the direction in which change requests are transported, are defined through transport routes. A consolidation path must be defined between the development system and the quality assurance system. This path is the standard transport route for the development system. For each transport from an SAP FTP server, a consolidation path SAP must be defined. A delivery path must be defined between the quality assurance system and the production system. To define transport routes, use the hierarchical list editor (the screen Display Transport Routes) with the standard configuration of system groups. To set up the hierarchical list editor, perform the following steps on the Domain Controller server:
1. Log on as system administrator using client 000. 2. Choose Tools Administration Transports Transport Management System (or use Transaction STMS).
The screen Transport Management System is displayed. 3. Choose Overview Systems.
The screen System Overview: Domain:
The screen Display Transport Routes is displayed. 5. To switch to change mode, choose Configuration DisplayChange. 6. Choose Configuration Standard config .
The screen Change transport routes is displayed. 7. Select 3 system group and choose Continue. 8. In the hierarchical list, your R/3 Systems and their transport routes are displayed under Transport Routes. 9. Save the configuration. 10. To check the configuration of the transport routes, choose Configuration Check All systems. 11. To distribute the configuration of transport routes to all R/3 Systems, choose Configuration Distribute. 12. To activate the configuration, choose Configuration Activate In all systems. You require authorization to log on in all systems. 13. Document the configuration in the section Configuration below, using the table Transport routes. To find out the type of transport route, choose Goto Graphical editor. Check the table if there are subsequent problems with the current configuration. 14. Choose Back.

6. Select either Modifiable or Not modifiable for Repository and client-independent Customizing and choose Enter. Objects should only be modifiable in the development system. 7. In the development system and any other system in which the global setting is set to Modifiable, you need to make additional settings on the screen System change option, which lists all name ranges and name spaces in the system. Normally only the customer name range and local objects are modifiable. If it is necessary to modify SAP standard objects, the affected components must first be set to modifiable. 8. Save the settings. 9. Before your systems become operative, document the system change option for each R/3 Systems below under the section Configuration, using the table System Change Option. Check the table if there are subsequent problems with the setting of the system change option. 10. Choose Back.
Checking and Changing Client Settings In the tables below, in the section Configuration Documentation, document the client settings in your three- system landscape (for the development system, the quality assurance system, and the production system). To find out or change the relevant client settings, proceed as follows: 1. Choose Tools Administration Administration Client admin. Client maintenance.
The screen Display View "Clients": Overview is displayed. Execute the following steps for all lines (clients). 2. Double-click a line.
The screen Display View "Clients": Detail is displayed. 3. Before the system becomes operative, document the attributes of the client in the tables below. 4. If there are subsequent problems in R/3 which possibly result from client settings, check the settings in the tables. To change or reset settings, in the screen Display View "Clients": Overview, choose Table view Display Change. Double-click the client and change the attributes as required. 5. Choose Back.
Checking RDDIMPDP Before the system becomes operative and whenever there are problems with imports, check whether the Import Dispatcher (report RDDIMPDP) is correctly scheduled as a background job: 1. Choose Tools CCMS Jobs Maintenance (or use Transaction SM37).
The screen Select Background Jobs is displayed. 2. Enter RDDIMPDP* in the field Job name, enter an * in the field User name and in the field Or start after event, deselect finished and active, and choose Enter to execute.
The screen Job Overview – Alphabetic is displayed. 3. The Job Overview should contain the job RDDIMPDP, and, additionally, for each client into which transport requests are to be imported, a job with the name RDDIMPDP_CLIENT_
The screen Display Job

must be indicated as event related in the field Job frequency as event periodic. The field Job start should indicate Planned start after event SAP_TRIGGER_RDDIMPDP for job RDDIMPDP, and Planned start after event SAP_TRIGGER_RDDIMPDP_CLIENT for all client-specific RDDIMPDP jobs. The Status should in both cases be released. 6. If one of the background jobs is not correctly planned or not planned at all, perform the task Scheduling RDDIMPDP as described below. 7. Choose Back.
Scheduling RDDIMPDP If performing the above task Checking RDDIMPDP revealed that the background jobs required for import were not correctly scheduled, perform the following steps:
1. If the background job that was not correctly scheduled is RDDIMPDP, log on using client 000. If the background job that was not correctly scheduled is RDDIMPDP_CLIENT_nnn (where nnn is the client), log on using that client (nnn). 2. Choose Tools ABAP Workbench Development ABAP Editor (or use Transaction SE38).
The screen ABAP Editor: Initial Screen is displayed. 3. In the field Program, enter the ABAP report RDDNEWPP, and choose Program Execute Directly. 4. After successful execution of the program, choose Back. 5. Perform the task Checking RDDIMPDP again for the job that was just scheduled.
