• Message type: E = Error

• Message class: RSODSO_TOOLS -

• Message number: 164

• Message text: Note the consequences that can occur if locks are deleted

What causes this issue?

Note that manually deleting persistent database locks can cause
inconsistencies during the data loading process.

System Response

Therefore before you delete any locks, ensure that there are no active
loading processes still running that require the relevant objects to be
locked. Otherwise there is the risk that the unprotected objects could
be changed by multiple simultaneous accesses, which can lead to
inconsistencies and errors in the data.

How to fix this error?

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

Procedure for System Administrators

The deletion of persistent database locks is logged in the application
log (SLG1).

• What is the cause and solution for SAP error message RSODSO_TOOLS164 - Note the consequences that can occur if locks are deleted ?

  The SAP error message RSODSO_TOOLS164 typically relates to issues with DataStore Objects (DSOs) in SAP BW (Business Warehouse). This error can occur when there are problems with the locks on the DSO, which can prevent data loading or processing.
  Cause:
  The error RSODSO_TOOLS164 usually arises due to:
  
  Locks on the DSO: This can happen if there are ongoing processes (like data loads or transformations) that have not been completed, leading to locks that prevent other operations from proceeding.
  Long-running processes: If a data load or transformation takes too long, it can lead to locks that block other operations.
  System issues: Sometimes, system performance issues or bugs can lead to locks not being released properly.
  
  Solution:
  To resolve the RSODSO_TOOLS164 error, you can take the following steps:
  
  Check for Active Processes: Use transaction codes like SM12 to check for locks on the DSO. Identify any active processes that may be holding locks.
  Terminate Long-Running Processes: If you find any processes that are stuck or taking too long, you may need to terminate them. This can be done through transaction SM37 (Job Monitoring) or SM12 (Lock Entries).
  Release Locks: If you determine that locks are no longer needed, you can manually delete them using transaction SM12. However, be cautious with this step.
  Monitor System Performance: Ensure that your system is performing optimally to prevent long-running processes in the future. This may involve checking system resources, optimizing queries, or adjusting data load schedules.
  Consult SAP Notes: Check for any relevant SAP Notes that may provide additional guidance or patches related to this error.
  
  Consequences of Deleting Locks:
  Deleting locks can have several consequences, including:
  
  Data Integrity Issues: If you delete locks while a data load or transformation is still in progress, it can lead to incomplete or corrupted data being written to the DSO.
  Inconsistent Reporting: Users may encounter inconsistent or incorrect data in reports if the underlying data is not fully loaded or processed.
  System Instability: Forcefully removing locks can lead to system instability, as it may disrupt ongoing processes and lead to further errors.
  Loss of Transactional Data: If a transaction is interrupted, you may lose important transactional data that was being processed.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SM12 (Lock Entries), SM37 (Job Monitoring), and RSA1 (Data Warehousing Workbench) for managing and monitoring DSOs.
  SAP Notes: Regularly check SAP Notes for updates or patches related to DSO management and error handling.
  Best Practices: Implement best practices for data loading and processing in SAP BW to minimize the occurrence of locks and related errors.
  
  Always ensure that you have proper backups and a recovery plan in place before making changes to locks or terminating processes in a production environment.
