UA_FORMULA049 - Details

• The SAP error message UA_FORMULA049 indicates that a specific method of a class cannot be used in the context where it is being called. This error typically arises in ABAP programming when there is an issue with the method's accessibility, the context in which it is being called, or the parameters being passed to it.
  Causes:
  
  Method Accessibility: The method might be declared as private or protected, and you are trying to access it from outside its allowed scope.
  Incorrect Context: The method may not be applicable in the current context or is not intended to be used in the way it is being called.
  Parameter Mismatch: The parameters being passed to the method may not match the expected types or number of parameters.
  Class Instantiation: The class may not be instantiated correctly, or the object reference might be null.
  Version Issues: There may be version discrepancies if the method was introduced in a later version
