How To Fix XT266 - Transport group &1 only contains systems with release lower than 4.5A

SAP Error Message - Details

• Message type: E = Error

• Message class: XT - Transport Management System

• Message number: 266

• Message text: Transport group &1 only contains systems with release lower than 4.5A

What causes this issue?

You cannot forward transport requests from the group &V1& directly to
to the system &V2&, since the transport program tp is incompatible. tp
cannot be adjusted at the moment.

System Response

The transport group &V1& cannot be adjusted.

Procedure for System Administrators

If you want to make transports between systems in the transport group
&V1& and the system &V2&, then you need a virtual system <VIR> with the
system &V2& as the communication system.
You must set the parameter NBUFFORM to 0 in the transport tool
configuration for this virtual system.
You can then forward requests from systems in group &V1& to the virtual
system <VIR>.
After the virtual system has been adjusted, you can forward and import
the requests to the system &V2&.

• What is the cause and solution for SAP error message XT266 - Transport group &1 only contains systems with release lower than 4.5A ?

  The SAP error message XT266 indicates that the transport group you are trying to work with contains only systems that have a release lower than 4.5A. This typically occurs when you are attempting to transport objects between systems that are not compatible due to their version differences.
  Cause:
  
  Version Compatibility: The transport group is configured to include systems that are all on a version lower than 4.5A. SAP has specific rules regarding transport compatibility, and systems must be on compatible versions to exchange transports.
  Transport Group Configuration: The transport group may have been incorrectly configured to include only older systems, or newer systems may not have been added to the transport group.
  
  Solution:
  
  
  Check Transport Group Configuration:
  
  Go to transaction code STMS (Transport Management System).
  Check the configuration of the transport group to ensure that it includes systems that are on version 4.5A or higher.
  If necessary, add systems with the appropriate version to the transport group.
  
  
  
  Upgrade Systems:
  
  If you have systems that are still on a version lower than 4.5A, consider upgrading them to a compatible version if feasible.
  
  
  
  Create a New Transport Group:
  
  If the current transport group cannot be modified to include compatible systems, consider creating a new transport group that includes systems with the required version.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that may provide additional guidance or solutions related to this error.
  
  
  
  Transport Request:
  
  Ensure that the transport request you are trying to release is compatible with the target system's version.
  
  
  
  Related Information:
  
  SAP Versioning: Understanding the versioning of SAP systems is crucial. Versions are typically denoted in the format of XX.YY, where XX is the major version and YY is the minor version.
  Transport Management System (TMS): Familiarize yourself with TMS, as it is the tool used to manage transports between different SAP systems.
  SAP Documentation: Refer to the official SAP documentation for detailed information on transport management and version compatibility.
  
  By following these steps, you should be able to resolve the XT266 error and ensure that your transport processes function smoothly.
