Compression of historical transaction data records
If you have selected the <ZH><LS>No Marker Updating</> </>indicator,
during the compression <ZH>no markers are adjusted.</> This function is
used to make changes to non-cumulatives that have yet to be initialized
visible at a later point in time. When loading and compressing <ZH>
historical transaction data records</> be aware of the following:
Before the compression takes place, the InfoCubes into which the
historical transaction data records are loaded show potentially <ZH>
incorrect results</>. These inconsistencies are resolved during the
compression process.
Once the historical transaction data records have been loaded into an
InfoCube, the relevant <ZH>aggregates contain the incorrect data</>. All
the incorrect aggregates are, therefore, deactivated during the
compression run and rebuilt. For performance reasons, SAP recommends
deactivating aggregates before a compression run with historical data,
and to then rebuild them after the compression run.
Handling non-cumulative initializations as historical transaction data
is not permitted and results in the termination of the compression run.

• What is the cause and solution for SAP error message RSM140 - Warning: Data could be lost; for more information, see the long text ?

  The SAP error message RSM140, which states "Warning: Data could be lost; for more information, see the long text," typically occurs in the context of data extraction or data transfer processes, particularly when using the SAP BW (Business Warehouse) or SAP BI (Business Intelligence) systems. This warning indicates that there may be a risk of data loss during the process, and it is essential to address the underlying issues to ensure data integrity.
  Cause:
  The warning can be triggered by several factors, including:
  
  Data Inconsistencies: There may be inconsistencies in the data being extracted or transferred, such as missing records or mismatched data types.
  Data Overwriting: If the data being loaded into a target InfoProvider (like an InfoCube or DataStore Object) is not properly managed, it may lead to overwriting existing data.
  Incorrect Data Mapping: If the mapping between source and target fields is not correctly defined, it can lead to data loss.
  Insufficient Data Volume: If the data volume being processed exceeds the limits set in the system, it may lead to truncation or loss of data.
  Process Interruptions: Any interruptions during the data load process (e.g., system crashes, network issues) can lead to incomplete data transfers.
  
  Solution:
  To resolve the RSM140 warning, consider the following steps:
  
  Check Long Text: Review the long text associated with the warning message for specific details about the potential data loss.
  Data Validation: Validate the data in the source system to ensure there are no inconsistencies or missing records.
  Review Data Mapping: Ensure that the mapping between source and target fields is correctly defined and that all necessary fields are included.
  Monitor Data Volume: Check the data volume being processed and ensure it is within acceptable limits. If necessary, adjust the data load settings.
  Error Logs: Review error logs and process chains for any additional error messages that may provide insight into the issue.
  Test Load: Perform a test load with a smaller dataset to identify if the issue persists and to isolate the cause.
  Backup Data: Before performing any data load operations, ensure that you have a backup of the existing data to prevent loss.
  Consult Documentation: Refer to SAP documentation or support notes related to the specific data extraction or loading process you are using.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to the RSM140 warning.
  SAP Community: Engage with the SAP Community forums for insights from other users who may have encountered similar issues.
  SAP BW/BI Documentation: Review the official SAP BW/BI documentation for best practices on data extraction and loading processes.
  
  By following these steps, you can mitigate the risk of data loss and ensure a smoother data extraction or transfer process in your SAP environment.
