• What is the cause and solution for SAP error message RSODSO_ROLLBACK251 - Error in In-Memory-optimized rollback (see longtext) ?

  The SAP error message RSODSO_ROLLBACK251 typically indicates an issue related to the rollback process in an in-memory optimized DataStore Object (DSO) in SAP BW/4HANA or SAP BW on HANA. This error can occur during data loading or processing when the system encounters a problem that prevents it from completing the operation successfully.
  Cause:
  
  Data Consistency Issues: The error may arise due to inconsistencies in the data being processed, such as duplicate records or invalid data formats.
  Memory Constraints: Insufficient memory resources can lead to failures during the rollback process, especially in in-memory optimized environments.
  Transaction Failures: If a transaction fails during data loading, the system attempts to roll back changes, which can trigger this error if it encounters issues during the rollback.
  Locking Issues: If there are locks on the DSO or related objects, it may prevent the rollback from completing successfully.
  System Configuration: Incorrect configuration settings for the DSO or the underlying database can also lead to this error.
  
  Solution:
  
  Check Data Consistency: Review the data being loaded into the DSO for any inconsistencies or duplicates. Ensure that the data adheres to the expected formats and constraints.
  Monitor Memory Usage: Check the memory usage of the HANA system. If memory is low, consider optimizing memory allocation or increasing the available resources.
  Review Transaction Logs: Analyze the transaction logs to identify any specific errors that occurred during the data loading process. This can provide insights into what caused the rollback to fail.
  Check Locks: Use transaction codes like SM12 to check for any locks on the DSO or related objects. If locks are found, resolve them before retrying the operation.
  Reconfigure DSO: If the issue persists, review the configuration settings of the DSO and ensure they are set up correctly for in-memory processing.
  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 resolve known issues.
