SAP BASIS NOTES -11

STMS (SAP Transport management System) :-

1) SAP normally follows 3 system landscape with 3 tier architecture. i.e. DEV, QAS, PRD.
2) One of the systems has to be configured as transport domain controller. This configuration is done as a   part of implementation i.e. immediately after executing SICK transaction.
3) The transaction to configure transport management. STMS
4) RFC’s are generated when the Transport Management System when continued R/3 system to communicate with all R/3 systems in a domain.

Q) What is a transport group?
A) SAP systems that share a common transport directory tree form a transport group.

Q) What is transport domain controller?
A) R/3 system with the reference configuration is called as the transaction domain controller.

Q) What is transport domain?
A) All R/3 systems that are planned to manage centrally using TMS form a transport domain.

In order to configure transaction domain controller we have to login using client 000 and user sap* or any user having similar authorization using sap*.

Configuring Transport domain controller:-
1) Login to SAP using client 000 and sap*
2) Go to STMS, it will propose the system as transport domain controller, provide the description and save.
3) Go to overview menu and select systems
4) Place the cursor on SYS ID and select SAP system display
5) Go to transport pool and check under global parameter transport directory. i.e. transport directory path (\usr\sap\trans)

Note: The above steps are performed in Dev System which we can assume as domain controller

Steps for Requesting inclusion of QAS and PRD systems into domain controller
Log on to QAS with 000 and SAP* go to STMS
Select other configuration
Provide the description and target hostname of the transport domain i.e. DEV system domain name and instance no and save
Login to Development using 000 and sap * and goto STMS
Select the QAS
Go to sap systems -> Approve
This will pop up message saying “Inclusion of system in Transport Domain” then click “Yes”

Note: Repeat the above steps for inclusion of PROD system also
In Dev distribute TMS configuration by selecting extras -> Distribute TMS configuration
It POPs us a message and then select “Yes”

Backup Domain Controller   
Backup domain controller holds the copy of reference configuration and configuration changes can be managed when transport domain controller is not available.

Steps in defining backup domain controller:
1. Log on to transport domain controller system using client 000 and SAP*. Go to STMS T-code.
2. In STMS screen go to overview -> systems -> select the R3 system to be defined as backup domain controller.
3. Go to SAP system -> Display
4. Go to communication tab -> Select change under backup, you have to mention “QAS” and save then it will give a pop-up windows requesting you to configure the changes immediately, select YES.
5. Go to Extras from menu -> Activate backup domain controller. It will give a pop-up windows as “Activate system QAS as a domain controller” click “YES”.

Transport Routes:
Transport routes indicate the roles of each systems and flow of change request.

Steps to configure transport routes:
1. Go to STMS T-code and Extras -> Settings -> Transport Routes  -> Select the desired editor and choose continue (By default graphical editor)
2. Go to overview -> Transport routes -> Select display or change mode
3. Go to configuration -> Standard configuration -> Three system in group.
4. Select the R3 system in the pop-up according to their roles and click continue and save and specify the type of configuration and choose continue, it will ask you to distribute and activate the change then select YES.

Q) What are the two editor modes in which we can configure the transport routes?
A) 1. Graphical Editor
     2. Hierarchical Editor   

Q) What are the various configuration methods available in STMS?
A)  1. Single system configuration
      2. Development and Production systems
      3. Three systems in a group

Q)  What is a standard transport layer?
A)  This describes the transport route that the data from the development systems follows.

Q)  What is SAP transport layer?
A)  It is a predefined transport layer for DEV classes of SAP standard objects

Create Transport Layer:
1. STMS -> Overview -> Transport routes -> Select change button -> select zoon in button -> Select the particular transport route -> Go to Edit -> Transport layer -> Create.
2. Enter the transport layer name and description.

Configuring transport routes manually:
1. STMS -> Overview -> Transport routes
2. Go to Edit -> Transport route and add transport route -> Select source and target and leave it then we get pop-up window transport layer and click continue.

Note: Development system consider as consolidation system. Quality system consider as delivery system. Production system is considered as integration system.

Enabling Quality assurance approval procedure (QAS):
1. Go to STMS -> Overview -> Transport routes -> Select change mode and double click on QAS System.
2. Go to System -> System attributes -> Delivery after configuration and click on procedure button.
3. Select the check box under the column “ASTV” as required and choose save.
4. Select distribute and activate (F8) button icon.

Q) What are the three approval steps you need to follow as a part of approval procedure in QAS?
A) 1. To be approved by system administrator
     2. To be approved by department
     3. To be approved by request owner

Using TMS on day to day operations:
Go to “STMS_IMPORT” = this will take us to the screen in which all the imports are available. Select the import that is transport request and click the truck button (Half loaded truck).

Note:
1. If the import request button are not appears under STMS_IMPORTS then go to Extras -> other request and select add enter the transport request number manually which you want to manually import.
2. Move transport number xyz to client 100.

Transporting request in OS Level:
1. Log on to any SAP system go to “\usr\sap\trans\bin” execute the command “TP add to buffer <request number> <SID>client <client number>”
2. To import the command is “TP import <request number><SID>Client <ClientNo> U0

Note: U0 is a qualifier to leave the transport in the buffer.

Q)  What are the various qualifier option or what are the various import options?
A) There are six import options
  1. Leave transport request in queue for later import
  2. Import transport request again
  3. Overwrite originals
  4. Overwrite objects in unconfirmed repairs
  5. Ignore unpermitted transport type
  6. Ignore predecessor relations
