• What is the cause and solution for SAP error message RSAN_OM107 - Conversion error: element &1 is not supported ?

  The SAP error message RSAN_OM107, which states "Conversion error: element &1 is not supported," typically occurs in the context of SAP BW (Business Warehouse) or SAP BW/4HANA when there is an issue with data conversion or transformation during the extraction, loading, or reporting processes.
  Cause:
  
  
  Unsupported Data Type: The error often arises when the system encounters a data type or element that is not supported for conversion. This can happen if the data source contains fields that are not compatible with the target data model or transformation rules.
  
  
  Incorrect Mapping: If there is a mismatch in the mapping of fields between the source and target, it can lead to this error. For example, if a field in the source is expected to be a numeric type but is being treated as a string in the target.
  
  
  Data Quality Issues: Sometimes, the data itself may contain unexpected values or formats that cannot be converted properly, leading to this error.
  
  
  Configuration Issues: Incorrect settings in the InfoObjects, transformations, or data sources can also lead to this error.
  
  
  Solution:
  
  
  Check Data Types: Review the data types of the elements involved in the transformation. Ensure that the source and target data types are compatible.
  
  
  Review Transformations: Go through the transformation rules defined in the Data Transfer Process (DTP) or the transformation itself. Make sure that all mappings are correct and that there are no unsupported conversions.
  
  
  Data Cleansing: If the issue is due to data quality, consider cleansing the data in the source system or applying filters in the DTP to exclude problematic records.
  
  
  Debugging: Use the SAP BW debugging tools to trace the data flow and identify where the conversion error is occurring. This can help pinpoint the exact element causing the issue.
  
  
  Update InfoObjects: If the InfoObjects have been changed or updated, ensure that all related transformations and DTPs are also updated accordingly.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific version of SAP BW you are using, as there may be known issues or patches available.
