  The SAP error message RS_MAPI_JSON102 Error in anyOf at & typically occurs in the context of SAP applications that utilize JSON data structures, particularly when working with APIs or data services that expect a specific JSON format. This error indicates that there is an issue with the JSON data being processed, specifically related to the anyOf validation schema.
  Cause:
  
  Invalid JSON Structure: The JSON data being sent or received does not conform to the expected structure defined in the API or service. This could be due to missing required fields, incorrect data types, or additional unexpected fields.
  Schema Mismatch: The JSON data does not match the schema defined for the API endpoint. The anyOf keyword in JSON Schema allows for validation against multiple schemas, and if the data does not match any of the specified schemas, this error can occur.
  Data Type Issues: If the data types of the values in the JSON do not match the expected types (e.g., a string is provided where a number is expected), this can trigger the error.
  Empty or Null Values: If required fields are empty or null, it can lead to validation failures.
  
  Solution:
  
  Validate JSON Structure: Use a JSON validator tool to check the structure of the JSON data being sent or received. Ensure that it adheres to the expected schema.
  Check API Documentation: Review the API documentation to understand the expected JSON structure, including required fields, data types, and any constraints.
  Debugging: If possible, log the JSON data being processed at the point of failure to identify discrepancies. Compare it against the expected schema.
  Adjust Data: Modify the JSON data to ensure it meets the requirements of the API. This may involve adding missing fields, correcting data types, or removing unnecessary fields.
  Testing: After making adjustments, test the API call again to see if the error persists.
