• What is the cause and solution for SAP error message /SRMSMC/CHANGE_INFO004 - Change info for relation (supplier &1, contact &2) is locked by user &3 ?

  The SAP error message /SRMSMC/CHANGE_INFO004 indicates that a change operation for a specific relation (in this case, a supplier and a contact) is currently locked by another user. This typically occurs in the Supplier Relationship Management (SRM) module when multiple users attempt to modify the same data simultaneously.
  Cause:
  
  Data Locking: The primary cause of this error is that the record you are trying to change is locked by another user. SAP uses a locking mechanism to prevent data inconsistencies that can arise from concurrent updates.
  Long-running Transactions: If a user has a long-running transaction that involves the same data, it can lead to locks that prevent others from making changes.
  Uncommitted Changes: If a user has made changes to the data but has not yet committed those changes, the record remains locked.
  
  Solution:
  
  Wait and Retry: The simplest solution is to wait for the other user to complete their transaction and then try again. You can check with your colleagues to see if they are working on the same data.
  Identify the Lock: Use transaction code SM12 to view the lock entries. You can check which user is holding the lock and the specific object that is locked.
  Release the Lock: If you have the necessary authorizations, you can manually release the lock from SM12. However, this should be done with caution, as it may lead to data inconsistencies if the other user is still working on the data.
  Communicate with Users: If you find that a specific user is frequently locking the data, it may be helpful to communicate with them to coordinate changes.
  Review Transaction Design: If this issue occurs frequently, consider reviewing the design of the transactions to minimize locking conflicts, such as optimizing the duration of transactions or implementing better user coordination.
  
  Related Information:
  
  Lock Management: Understanding how SAP handles locks can help in troubleshooting. Locks can be either exclusive (preventing all other access) or shared (allowing read access).
  Transaction Codes: Familiarize yourself with relevant transaction codes like SM12 (to view locks), SM21 (to check system logs), and SM37 (to monitor background jobs) for better troubleshooting.
  User Training: Ensure that users are trained on how to manage their transactions efficiently to minimize locking issues.
  
  If the problem persists or if you encounter additional issues, it may be beneficial to consult with your SAP Basis team or technical support for further assistance.
