• What is the cause and solution for SAP error message TK644 - User & is not authorized to merge requests ?

  The SAP error message TK644 indicates that a user is not authorized to merge requests in the system. This typically occurs in the context of transport management, where users are trying to merge transport requests but lack the necessary permissions.
  Cause:
  
  Authorization Issues: The user does not have the required authorization objects to perform the merge operation. This could be due to missing roles or authorizations in their user profile.
  Transport Management Configuration: The transport management system (TMS) may have specific configurations that restrict certain users from merging requests.
  User Role Changes: If the user's roles or authorizations were recently changed, they may have lost the necessary permissions to perform the merge.
  
  Solution:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after the error occurs to see which authorization check failed. This will provide insight into what specific authorization is missing.
  Review the user's roles and authorizations in transaction SU01 or PFCG to ensure they have the necessary permissions.
  
  
  
  Assign Required Roles:
  
  If the user lacks the necessary roles, work with your SAP security team to assign the appropriate roles that include the required authorizations for merging transport requests.
  Common authorization objects related to transport management include S_TRANSPRT (Transport Management) and S_TCODE (Transaction Codes).
  
  
  
  Consult Transport Management Configuration:
  
  Check the transport management configuration to ensure that there are no restrictions placed on the user or user groups that would prevent merging requests.
  
  
  
  Testing:
  
  After making changes to the user's authorizations, have the user log out and log back in to ensure that the new permissions take effect.
  Attempt the merge operation again to verify that the issue has been resolved.
