• What is the cause and solution for SAP error message CL_SADL_GW_MDE_MSGX034 - & is not decimal ?

  The SAP error message CL_SADL_GW_MDE_MSGX034 typically indicates that there is an issue with the data type of a field that is expected to be a decimal but is not. This error often arises in the context of SAP Gateway and the SADL (SAP ABAP Programming Model for SAP Fiori) framework when dealing with OData services.
  Cause:
  
  
  Data Type Mismatch: The error usually occurs when the data being processed does not conform to the expected decimal format. This could be due to:
  
  Incorrect data being sent from the frontend (e.g., Fiori app).
  Data being retrieved from the database that does not match the expected decimal format.
  Configuration issues in the OData service or model.
  
  
  
  Localization Issues: Sometimes, the issue can arise from localization settings where the decimal separator is different (e.g., using a comma instead of a dot).
  
  
  Invalid Input: If a user inputs a value that cannot be converted to a decimal (e.g., letters or special characters), this error may occur.
  
  
  Solution:
  
  
  Check Input Data: Ensure that the data being sent to the OData service is in the correct decimal format. Validate user inputs to ensure they conform to expected formats.
  
  
  Review OData Service: Check the OData service definition and ensure that the data types are correctly defined. Make sure that the fields expected to be decimal are correctly mapped in the service.
  
  
  Debugging: Use transaction codes like /IWFND/ERROR_LOG to check for detailed error logs. This can provide more context on where the error is occurring.
  
  
  Localization Settings: Verify the localization settings in your SAP system. Ensure that the decimal separator is set correctly according to your region's standards.
  
  
  Data Conversion: If you are manipulating data before sending it to the OData service, ensure that any conversions to decimal types are handled correctly.
  
  
  Testing: Test the OData service using tools like Postman or the SAP Gateway Client to see if the error can be reproduced with specific inputs.
