• What is the cause and solution for SAP error message RSAOLTP005 - Field list contains rows with various keys ?

  The SAP error message RSAOLTP005, which states "Field list contains rows with various keys," typically occurs in the context of data extraction or data transfer processes, particularly when working with SAP BW (Business Warehouse) or SAP Data Services. This error indicates that the field list being processed contains rows that have different keys, which can lead to inconsistencies in data extraction or transformation.
  Cause:
  
  
  Inconsistent Key Fields: The most common cause of this error is that the data being processed has inconsistent key fields. For example, if you are trying to extract data from a table or InfoProvider that has a composite key, and the rows being processed do not share the same key structure, this error will occur.
  
  
  Data Model Issues: There may be issues with the data model, such as missing or incorrectly defined key fields in the source or target systems.
  
  
  Transformation Logic: If there are transformations applied that change the key fields or if the mapping is not correctly defined, it can lead to this error.
  
  
  Data Source Configuration: The configuration of the data source in SAP BW or the extraction settings may not be aligned with the actual data structure.
  
  
  Solution:
  
  
  Check Key Fields: Review the key fields in the source data and ensure that they are consistent across all rows. Make sure that the key fields defined in the data model match the actual data being processed.
  
  
  Adjust Data Model: If there are discrepancies in the data model, adjust the model to ensure that the key fields are correctly defined and consistent.
  
  
  Review Transformation Logic: If you are using transformations, check the logic to ensure that it does not inadvertently change the key fields or create inconsistencies.
  
  
  Data Source Configuration: Verify the configuration of the data source in SAP BW. Ensure that the extraction settings are correctly set up to match the structure of the source data.
  
  
  Debugging: If the issue persists, consider debugging the data flow to identify where the inconsistency arises. This may involve checking the data in the source system, the transformation rules, and the target structure.
  
  
  Consult Documentation: Refer to SAP documentation or support notes related to the specific version of SAP you are using, as there may be known issues or additional guidance available.
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any specific fixes or patches related to this error message.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have found.
  Data Quality Checks: Implement data quality checks to ensure that the data being processed is clean and consistent before extraction or transformation.
  
  By following these steps, you should be able to identify the root cause of the RSAOLTP005 error and implement a solution to resolve it.
