• What is the cause and solution for SAP error message TN166 - &1 &2 was imported without using Support Package Manager ?

  The SAP error message TN166 indicates that a transport request (TR) was imported into the system without using the Support Package Manager (SPM). This can lead to inconsistencies in the system, as the Support Package Manager is designed to ensure that all necessary components and dependencies are handled correctly during the import process.
  Cause:
  The error typically arises when:
  
  A transport request is imported directly using transaction codes like STMS (Transport Management System) or SE09 (Transport Organizer) instead of using the Support Package Manager.
  The transport request contains changes that are part of a support package or enhancement package that should be applied through SPM to ensure proper sequencing and dependency management.
  
  Solution:
  To resolve this issue, you can follow these steps:
  
  
  Identify the Transport Request: Determine which transport request is causing the error. The error message will usually specify the transport request number.
  
  
  Check Dependencies: Review the contents of the transport request to understand what changes it includes and whether it has dependencies on other requests or components.
  
  
  Use Support Package Manager:
  
  If the transport request is part of a support package or enhancement package, you should re-import it using the Support Package Manager.
  Access the Support Package Manager via transaction code SPAM or SAINT (for add-ons).
  Load the relevant support package or enhancement package and ensure that the transport request is included in the import process.
  
  
  
  Re-import the Transport Request: If necessary, you may need to revert the changes made by the transport request that was imported incorrectly. This can be done by:
  
  Using the STMS transaction to import the transport request again, ensuring that you select the option to use the Support Package Manager.
  
  
  
  Check for System Consistency: After re-importing, check the system for any inconsistencies or issues that may have arisen due to the incorrect import.
  
  
  Consult SAP Notes: If the issue persists, check the SAP Support Portal for any relevant SAP Notes that may provide additional guidance or solutions specific to your version of SAP.
  
  
  Related Information:
  
  SAP Notes: Always check for relevant SAP Notes that may address specific issues related to transport management and support package imports.
  Transport Management System (TMS): Familiarize yourself with TMS and its role in managing transports within SAP systems.
  Support Package Manager (SPM): Understand the importance of using SPM for applying support packages and enhancements to ensure system integrity.
  
  By following these steps, you should be able to resolve the TN166 error and ensure that your SAP system remains stable and consistent.
