• What is the cause and solution for SAP error message SRT_CORE018 - ASSERT failed: field value not a valid Boolean ?

  The SAP error message SRT_CORE018 ASSERT failed: field value not a valid Boolean typically occurs in the context of SAP's web services or integration scenarios, particularly when dealing with the SAP Process Integration (PI) or SAP Process Orchestration (PO) environments. This error indicates that a value expected to be a Boolean (true/false) is not valid, which can lead to assertion failures in the system.
  Cause
  The error can be caused by several factors, including:
  
  Incorrect Data Type: The system is expecting a Boolean value (e.g., true or false), but it receives a different data type (e.g., a string, number, or null).
  Mapping Issues: If you are using mappings (e.g., graphical or XSLT mappings) in your integration flow, there may be a mapping error where a field is incorrectly mapped to a Boolean type.
  Service Interface Definition: The service interface may have been defined incorrectly, leading to mismatches in expected data types.
  Faulty Configuration: Configuration settings in the integration scenario may not align with the expected data types.
  
  Solution
  To resolve the SRT_CORE018 error, you can take the following steps:
  
  
  Check the Data Mapping:
  
  Review the mappings in your integration flow to ensure that all fields expected to be Boolean are correctly mapped.
  Ensure that the source data being sent to the service is in the correct format.
  
  
  
  Validate Input Data:
  
  Inspect the input data being sent to the service. Ensure that any fields expected to be Boolean are indeed set to true or false and not to any other value.
  
  
  
  Review Service Interface:
  
  Check the service interface definition in the Enterprise Services Repository (ESR) to ensure that the data types are correctly defined.
  If necessary, regenerate the service interface or update the data types.
  
  
  
  Debugging:
  
  Use the SAP PI/PO monitoring tools to trace the message flow and identify where the error occurs.
  Look for any logs or traces that provide more context about the error.
  
  
  
  Testing:
  
  After making changes, test the integration scenario to ensure that the error is resolved and that the data is processed correctly.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or community forums for additional insights or similar issues encountered by other users.
