• What is the cause and solution for SAP error message CME_CHAR808 - No mapping possible if multiple values are used in the data set ?

  The SAP error message CME_CHAR808 indicates that there is an issue with mapping values in a dataset when multiple values are used. This typically occurs in the context of data extraction, transformation, or loading processes, particularly in SAP BW (Business Warehouse) or SAP HANA environments.
  Cause:
  The error arises when the system encounters a situation where it cannot determine a single mapping for a characteristic because multiple values are provided. This can happen in scenarios such as:
  
  Multiple Values in a Filter: If a filter is applied that includes multiple values for a characteristic, and the system is unable to resolve which value to use for mapping.
  Inconsistent Data: The dataset may contain inconsistent or conflicting values that cannot be reconciled.
  Incorrect Data Model: The data model may not be set up to handle multiple values for the characteristic in question.
  
  Solution:
  To resolve the CME_CHAR808 error, consider the following steps:
  
  
  Review the Data Input: Check the dataset for the characteristic that is causing the issue. Ensure that it does not contain multiple values where a single value is expected.
  
  
  Adjust Filters: If you are using filters in your query or data extraction, modify them to ensure that only one value is being passed for the characteristic in question.
  
  
  Data Cleansing: Clean the data to remove any inconsistencies or duplicates that may lead to multiple values being present.
  
  
  Mapping Configuration: Review the mapping configuration in your data model. Ensure that it is set up to handle the expected values correctly.
  
  
  Use Aggregation: If applicable, consider using aggregation functions to consolidate multiple values into a single value that can be mapped.
  
  
  Consult Documentation: Refer to SAP documentation or support resources for specific guidance related to the version of SAP you are using, as there may be version-specific considerations.
  
  
  Testing: After making adjustments, test the data extraction or transformation process again to ensure that the error is resolved.
