• What is the cause and solution for SAP error message 42491 - Contents of info object unchanged (export reset) ?

  The SAP error message 42491, which states "Contents of info object unchanged (export reset)," typically occurs in the context of data extraction or data transfer processes, particularly when working with InfoObjects in SAP BW (Business Warehouse) or SAP BI (Business Intelligence).
  Cause:
  This error message usually indicates that the system has detected that the contents of an InfoObject have not changed since the last time it was exported or processed. This can happen due to several reasons:
  
  
  No New Data: The data being extracted or processed has not changed since the last extraction, leading the system to determine that there is nothing new to export.
  
  
  Data Source Configuration: The data source may not be configured correctly, or there may be issues with the data flow that prevent new data from being recognized.
  
  
  Delta Mechanism: If you are using a delta mechanism for data extraction, it may not have identified any new records to extract.
  
  
  InfoObject Settings: The settings of the InfoObject may not allow for changes to be recognized, or there may be issues with the data model.
  
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Data Source: Verify that the data source is correctly configured and that there is indeed new data available for extraction. You can do this by checking the source system.
  
  
  Review Delta Settings: If you are using delta extraction, ensure that the delta mechanism is functioning correctly. Check if the delta queue has any entries and if the last delta extraction was successful.
  
  
  Reprocess the Data: If you suspect that the data should have changed, try reprocessing the data load. This can sometimes help in recognizing changes that were not previously detected.
  
  
  Check InfoObject Configuration: Review the configuration of the InfoObject in question. Ensure that it is set up correctly and that there are no restrictions that would prevent it from recognizing changes.
  
  
  Monitor Load Process: Use transaction codes like RSA1 (Data Warehousing Workbench) to monitor the load process and check for any warnings or errors that might provide additional context.
  
  
  Consult Logs: Check the application logs (transaction SLG1) for any related messages that might give more insight into why the data is not being recognized as changed.
  
  
  Data Consistency: Ensure that the data in the source system is consistent and that there are no issues with data integrity that could affect the extraction process.
