• What is the cause and solution for SAP error message SRM_ECM_MSG175 - Error during HASH calculation (optimistic locking) ?

  The SAP error message SRM_ECM_MSG175, which indicates "Error during HASH calculation (optimistic locking)," typically arises in the context of SAP Supplier Relationship Management (SRM) when there is an issue with data consistency during a transaction. This error is often related to optimistic locking mechanisms that SAP uses to prevent data conflicts when multiple users or processes attempt to modify the same data simultaneously.
  Cause:
  
  
  Optimistic Locking Conflict: This error usually occurs when two or more users are trying to update the same data record at the same time. The system uses a hash value to ensure that the data has not changed since it was last read. If the hash value does not match, it indicates that another transaction has modified the data, leading to a conflict.
  
  
  Data Consistency Issues: If there are inconsistencies in the data or if the data has been changed by another process after it was read, this can trigger the error.
  
  
  Network Issues: Sometimes, network latency or interruptions can cause the hash calculation to fail.
  
  
  Solution:
  
  
  Retry the Operation: The simplest solution is to retry the operation. If the error was due to a temporary conflict, retrying may succeed.
  
  
  Check for Concurrent Updates: Investigate if multiple users or processes are trying to update the same record simultaneously. If so, coordinate the updates to avoid conflicts.
  
  
  Review Data Changes: Ensure that the data being modified has not been changed by another transaction. You may need to refresh the data before attempting to save changes.
  
  
  Debugging: If the issue persists, consider enabling debugging or logging to capture more details about the error. This can help identify the specific conditions under which the error occurs.
  
  
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes or patches that may address this specific error. There may be known issues or updates that can resolve the problem.
  
  
  System Configuration: Review the system configuration related to locking and transaction handling. Ensure that the settings are appropriate for your business processes.
  
  
  Related Information:
  
  
  Optimistic Locking: This is a concurrency control method that allows multiple transactions to proceed without locking resources. It checks for conflicts only at the time of committing the transaction.
  
  
  Hash Calculation: The hash value is a unique identifier generated based on the data in the record. If the data changes, the hash value will also change, indicating that the record has been modified.
  
  
  SAP SRM Documentation: Refer to the official SAP documentation for SRM for more details on transaction handling and error messages.
  
  
  If the problem continues after trying the above solutions, it may be necessary to involve your SAP Basis or technical support team for further investigation and resolution.
