• What is the cause and solution for SAP error message CL_SADL_GW_MDE_MSGX036 - & is not boolean ?

  The SAP error message CL_SADL_GW_MDE_MSGX036 typically indicates that there is an issue with a data type mismatch in a query or operation involving the SAP Gateway and the SADL (SAP ABAP Programming Model for SAP Fiori) framework. The specific message "is not boolean" suggests that the system expected a boolean value (true/false) but received a different data type instead.
  Cause:
  
  Data Type Mismatch: The most common cause of this error is that a field or parameter that is expected to be of boolean type is being passed a value of a different type (e.g., string, integer).
  Incorrect Query Structure: If you are using a query that involves filters or conditions, the structure of the query may not be correctly defined, leading to the system interpreting the data incorrectly.
  Model Definition Issues: There may be issues in the definition of the data model where the expected data types are not correctly specified.
  
  Solution:
  
  Check Data Types: Review the data types of the fields being used in your query or operation. Ensure that any field expected to be boolean is indeed being passed a boolean value.
  Review Query Logic: If you are using a query with filters, check the logic and ensure that the conditions are correctly defined. Make sure that boolean conditions are being used appropriately.
  Debugging: Use debugging tools in SAP to trace the execution of the code and identify where the data type mismatch is occurring. This can help pinpoint the exact location of the issue.
  Model Adjustments: If the issue is related to the data model, you may need to adjust the model definition to ensure that the expected data types are correctly specified.
