• What is the cause and solution for SAP error message ABAP_TESTDOUBLE034 - &4 Double cannot be created for constructors with mandatory parameters ?

  The SAP error message ABAP_TESTDOUBLE034 indicates that there is an issue with the creation of a double (floating-point number) in the context of a constructor that has mandatory parameters. This error typically arises in ABAP when you are trying to instantiate a class or call a method that requires mandatory parameters, but the parameters are not being provided correctly.
  Cause:
  
  Mandatory Parameters: The constructor of the class you are trying to instantiate has mandatory parameters that must be provided. If these parameters are not supplied, the system cannot create the instance of the class.
  Incorrect Data Type: If you are trying to pass a value that cannot be converted to a double or if the value is not in the expected format, this error may occur.
  Syntax Errors: There may be syntax errors in the code that prevent the correct execution of the constructor.
  
  Solution:
  
  
  Check Constructor Definition: Review the constructor of the class you are trying to instantiate. Ensure that you are providing all mandatory parameters when creating an instance of the class.
  Example:
  CLASS my_class DEFINITION.
    PUBLIC SECTION.
      METHODS constructor IMPORTING iv_param1 TYPE i iv_param2 TYPE f.
  ENDCLASS.
  
  CLASS my_class IMPLEMENTATION.
    METHOD constructor.
      " Constructor logic
    ENDMETHOD.
  ENDCLASS.
  
  " Correct instantiation
  DATA(lo_instance) = NEW my_class( iv_param1 = 10 iv_param2 = 3.14 ).
  
  
  Provide Correct Values: Ensure that the values you are passing to the constructor are of the correct data type and format. If the constructor expects a floating-point number, make sure you are passing a valid float.
  
  
  Debugging: If you are unsure where the error is occurring, use the ABAP debugger to step through the code and check the values being passed to the constructor.
  
  
  Review Related Code: Check for any related code that might be affecting the instantiation of the class. This includes any factory methods or other classes that might be involved in the creation process.
  
  
  Related Information:
  
  ABAP Documentation: Refer to the official SAP documentation for more details on class constructors and parameter handling in ABAP.
  SAP Community: You can search for similar issues on the SAP Community forums, where other developers may have encountered and resolved similar problems.
  Error Handling: Implement error handling in your code to gracefully manage situations where parameters may not be provided or are invalid.
  
  By ensuring that all mandatory parameters are provided and are of the correct type, you should be able to resolve the ABAP_TESTDOUBLE034 error.
