• What is the cause and solution for SAP error message ESH_ENG_CDS_HANA104 - &1: Conversion error ?

  The SAP error message ESH_ENG_CDS_HANA104 typically indicates a conversion error that occurs when the system is trying to convert data types or values in a Core Data Services (CDS) view or when executing a query against a HANA database. This error can arise from various issues, such as incompatible data types, incorrect data formats, or issues with the underlying data model.
  Causes:
  
  Data Type Mismatch: The data being processed may not match the expected data type. For example, trying to convert a string to a number when the string contains non-numeric characters.
  Null Values: Attempting to convert null values or empty strings into a non-nullable data type can lead to conversion errors.
  Incorrect Data Format: If the data format does not match the expected format (e.g., date formats), it can cause conversion issues.
  Inconsistent Data: Data inconsistencies in the underlying tables can lead to conversion errors when the CDS view is executed.
  CDS View Definition: There may be issues in the definition of the CDS view itself, such as incorrect annotations or data type definitions.
  
  Solutions:
  
  Check Data Types: Review the data types of the fields in the CDS view and ensure that they match the expected types in the underlying database tables.
  Data Cleansing: Clean the data in the underlying tables to ensure that there are no invalid or inconsistent values that could cause conversion errors.
  Handle Null Values: Implement logic in the CDS view to handle null values appropriately, such as using COALESCE or CASE statements to provide default values.
  Review CDS View Definition: Check the definition of the CDS view for any errors or inconsistencies. Ensure that all annotations and data types are correctly defined.
  Test with Sample Data: Run tests with sample data to identify specific records that may be causing the conversion error. This can help isolate the issue.
  Check HANA Database Logs: Review the HANA database logs for any additional error messages or details that may provide more context about the conversion error.
