• What is the cause and solution for SAP error message RSDMD290 - Delta handling for record &1, field '&2': Value modified from &3 to &4 ?

  The SAP error message RSDMD290 indicates that there is an issue with delta handling in the context of data extraction or data loading in SAP BW (Business Warehouse). Specifically, this error occurs when a value in a delta record has been modified, which can lead to inconsistencies in the data being processed.
  Cause:
  The error message RSDMD290 is triggered when:
  
  A delta record is being processed, and the value of a specific field has changed from its previous value to a new value.
  This typically happens when the data source is set up to handle deltas, but the underlying data has been modified in a way that is not compatible with the delta logic.
  For example, if a record was previously loaded with a certain value and then that value is changed in the source system, the delta process may not be able to handle this change correctly.
  
  Solution:
  To resolve the RSDMD290 error, consider the following steps:
  
  
  Check Data Source Configuration: Ensure that the data source is correctly configured for delta handling. Review the settings in the DataSource and make sure that the delta mechanism is appropriate for the type of data being processed.
  
  
  Review Data Changes: Investigate the changes made to the data in the source system. If the data was modified in a way that is not compatible with the delta logic, you may need to adjust how the data is being updated or consider using a full load instead of a delta load.
  
  
  Perform a Full Load: If the delta handling is causing issues, you might want to perform a full data load to reset the data in the target system. This can help to clear any inconsistencies that have arisen from delta processing.
  
  
  Check for Data Consistency: Ensure that the data in the source system is consistent and that there are no conflicting updates. This may involve checking for duplicate records or ensuring that the primary keys are unique.
  
  
  Consult SAP Notes: Look for any relevant SAP Notes that may address this specific error. SAP frequently updates its documentation and provides solutions for known issues.
  
  
  Monitor Data Changes: Implement monitoring for data changes in the source system to better understand when and how data is being modified, which can help prevent similar issues in the future.
  
  
  Related Information:
  
  Delta Handling: Delta handling is a mechanism in SAP BW that allows for the efficient transfer of only the changed data from the source system to the target system, rather than transferring the entire dataset.
  DataSource: A DataSource in SAP BW is a structure that defines how data is extracted from a source system. It includes settings for delta handling, extraction methods, and data transformation.
  SAP BW: SAP Business Warehouse is a data warehousing solution that allows organizations to consolidate and analyze data from various sources.
  
  If the issue persists after following these steps, it may be beneficial to engage with SAP support or consult with a technical expert familiar with SAP BW and delta processing.
