• What is the cause and solution for SAP error message MO035 - Error when locking prototype ?

  The SAP error message MO035, which states "Error when locking prototype," typically occurs in the context of production planning and control, particularly when dealing with material master data or production orders. This error indicates that the system is unable to lock a prototype or a specific object for processing, which can hinder operations such as creating or modifying production orders.
  Causes of MO035 Error
  
  
  Lock Conflicts: The most common cause is that another user or process is currently accessing the prototype or object you are trying to lock. SAP uses a locking mechanism to prevent data inconsistencies, and if the object is already locked, you will encounter this error.
  
  
  Database Issues: There may be underlying database issues that prevent the locking mechanism from functioning correctly.
  
  
  Authorization Issues: The user may not have the necessary authorizations to lock the object, leading to this error.
  
  
  System Performance: If the system is under heavy load or experiencing performance issues, it may fail to lock the object in a timely manner.
  
  
  Configuration Issues: Incorrect configuration settings in the SAP system can also lead to locking issues.
  
  
  Solutions to MO035 Error
  
  
  Check for Locking Users: Use transaction code SM12 to check for existing locks on the object. If you find that another user is holding the lock, you may need to wait for them to release it or contact them to resolve the issue.
  
  
  Retry the Operation: Sometimes, simply retrying the operation after a short period can resolve the issue, especially if it was caused by a temporary lock.
  
  
  Review Authorizations: Ensure that the user has the necessary authorizations to perform the action. You can check this with transaction code SU53 to see if there are any authorization failures.
  
  
  Check System Performance: Monitor system performance and check for any issues that may be affecting the locking mechanism. You can use transaction codes like ST22 (dump analysis) and SM21 (system log) to identify any underlying problems.
  
  
  Consult Basis Team: If the issue persists, it may be necessary to involve your SAP Basis team to investigate any database or configuration issues that could be causing the locking problem.
  
  
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error. There may be patches or updates that can resolve the issue.
