Introduction:


Change Request Management (CHARM). When should you perform the steps provided in this document?

  1. If you are adding a new Quality system to a Landscape.

  2. If you want to add/remove a Quality client in an existing system of a landscape.

  3. If you want to update the Logical Component Groups.

  4. if you want to Redefine your landscape.


NOTE: *Modifying Logical Component Groups or Changing TMS while a ChaRM project is active can be very impactful for all charm changes. Please consult ChaRM expert before making any changes.

 

Add/remove a Quality system from a landscape


All below stems must be performed in the given order:

Step1: Adjusting the TMS so that Dev System is feeding into two quality systems

Step2: Update the Logical Component Groups

Step3: Redefining the Landscape

Step4: Update the Batch Jobs

 

Step1: Adjusting the TMS so that Dev System is feeding into two quality systems.


I will discuss two examples here. One related to adding an additional quality system and second example will be of adding multiple clients within the same system.

Example1: DR4 system wants to feed data into two Quality systems QR4 and QR8 and finally Prod PR4 wants to collect data from QR4 system.

Example 2: DRN Dev system wants to feed data into multiple clients within QRN system i.e. (QRN:900,910,920)

Step2: Update the Logical Component Groups



  1. SLAN

  2. Select the solution corresponding to your environment. In this scenario we are using "main solution".


  3. System Landscape > Assign Technical Systems


  4. Search and Select the Logical Component group of the project for which you want to do the modification and add the new Quality system and click OK. (if you don't see or have a different system type then use Tcode: /nmaint_roles to defined the new system type as Quality Assurance System 2 )



 

Step3: Redefining the Landscape



  1. Go to the Phase Cycle in Edit mode and Click Redefine Landscape.


  2. Everything should be green on the next screen for "Check Prerequisites". If not then first fix those errors.


  3. Click Next


  4. Add/Keep by clicking the checkbox, the new additional Quality system/clients as target from Dev boxes.

  5. * Uncheck the Development Workbench system only if shown as a target from customizing client (DR4:400 > DR4:410 in this scenario). This option comes if in TMS you have defined Workbench client as target client for customizing.


  6. Click Next. Validate all details are looking good on next screen and click '"Confirm".


NOTE: *Please notice that all the projects in Charm that are using above modified logical component Group will be affected by this change and you will have to Redefine the landscape for all those projects. It is not necessary to add this extra quality box for all those projects and you can uncheck this Quality box when Redefining if not needed.

Step4: Adjust the quality transport import jobs from the task list.




 

Step 5: (OPTIONAL) Use report RSCTS_OBJ_TRACK_REMOVE_SYSTEM. If needed you can remove this newly added quality system for CTS Transport tracking. This way you will not receive DGP errors related to this additional Quality system.

 

Conclusion


In 7.2 SAP has made it extremely simple to modify logical components while change cycle is still open. In 7.1 it was extremely difficult to perform these activities and in certain scenarios it was not possible at all.

During step redefine a landscape :

You are allowed to remove only quality systems and clients from a change cycle in motion.

You are allowed to even switch the quality system with another quality system but transport movement up to that moment would be manual or by a system copy.

SAP doesn't allow to modify the development or production system when a change cycle is active. See Note below for exception to this scenario: 2587310 - Remove Development and Production systems during redefine landscape

Additional Info:

The transport tracks overview contains the following elements and functions:

  • Tiles represent systems connected by transport routes.

  • Dotted lines represent connections between retrofit systems and their source development systems.

  • Select the checkbox in a system tile to select or deselect a system in a transport track. After deselecting a system, all follow-on systems that cannot be reached anymore are automatically deselected.

  • When the application calculates the transport tracks, the source systems must be the ones defined in the logical components of the branch. All other systems on the transport tracks must be in scope of the entire logical component groups under the change control landscape or the solution that is assigned to the cycle.

  • A valid transport track must have one development system and at least one production system. If deselecting a system makes the whole transport track invalid, all the systems of the track will be automatically deselected. Keep at least one valid transport track for creating a task list.

  • When redefining a system landscape, you are not allowed to deselect existing development or production systems in the task list and if you add or remove target systems you have to take care of the consistency of the import queue and transport status of the relevant systems by yourself.

  • Retrofit systems cannot be added or removed in the overview. Edit them in the retrofit systems table.
