• What is the cause and solution for SAP error message 03115 - Part collision with separate locks ?

  The SAP error message "03115: Part collision with separate locks" typically occurs in the context of SAP's lock management system, particularly when dealing with object locks in a multi-user environment. This error indicates that there is a conflict between different locks on the same object, which can happen when multiple users or processes are trying to access or modify the same data simultaneously.
  Cause:
  
  Concurrent Access: The error usually arises when two or more users or processes attempt to lock the same object (e.g., a database record) in a way that is incompatible. For example, one user may have a lock for reading while another tries to write.
  Lock Table Overflow: If the lock table is full, it may lead to issues where new locks cannot be acquired, resulting in conflicts.
  Improper Lock Management: If the application logic does not handle locks properly, it can lead to situations where locks are held longer than necessary or are not released correctly.
  
  Solution:
  
  Identify Lock Conflicts: Use transaction codes like SM12 (to view and manage locks) to identify which users or processes are holding locks on the object in question. This can help you understand the source of the conflict.
  Release Locks: If you find that a lock is being held unnecessarily, you can manually release it using SM12. However, be cautious when doing this, as it may disrupt the user or process holding the lock.
  Optimize Locking Logic: Review the application code to ensure that locks are acquired and released appropriately. Minimize the duration for which locks are held and avoid unnecessary locking.
  Increase Lock Table Size: If the lock table is frequently full, consider increasing its size. This can be done by adjusting the profile parameters in the SAP system.
  Use Appropriate Lock Modes: Ensure that the correct lock modes (e.g., shared vs. exclusive) are being used based on the operation being performed.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as:
  
  SM12: Display and manage locks.
  SM21: System log for monitoring system messages.
  ST22: Dump analysis for checking for any short dumps related to locking issues.
  
  
  SAP Notes: Check SAP Notes for any known issues or patches related to locking mechanisms. You can search for specific notes that address the error message or related locking issues.
  Documentation: Review SAP documentation on lock management and concurrency control to better understand how locks work and best practices for managing them.
  
  If the issue persists after trying the above solutions, it may be beneficial to consult with your SAP Basis team or reach out to SAP support for further assistance.
