• What is the cause and solution for SAP error message FMCCAVC750 - Call of method &1 not allowed in class &2 ?

  The SAP error message FMCCAVC750, which states "Call of method &1 not allowed in class &2," typically indicates that there is an attempt to call a method that is not permitted in the specified class. This can occur due to various reasons, such as:
  Causes:
  
  Access Control: The method being called may not be accessible from the context in which it is being called. This could be due to visibility restrictions (e.g., private or protected methods).
  Incorrect Class Usage: The method may not be defined in the class you are trying to call it from, or it may be defined in a different class that is not instantiated or accessible.
  Static vs. Instance Method: If you are trying to call an instance method statically or vice versa, this can lead to this error.
  Inheritance Issues: If the method is defined in a parent class and you are trying to call it from a child class without proper inheritance or instantiation, it may lead to this error.
  Method Signature Mismatch: If the method signature does not match the expected parameters, it can also lead to this error.
  
  Solutions:
  
  Check Method Accessibility: Ensure that the method you are trying to call is accessible from the context you are calling it from. If it is private or protected, consider changing its visibility or using a public method to access it.
  Verify Class and Method Existence: Double-check that the method exists in the class you are trying to call it from. If it is in a different class, ensure you are using the correct instance of that class.
  Correct Method Call Type: Make sure you are calling the method correctly (static vs. instance). If it is an instance method, ensure you have created an instance of the class before calling it.
  Review Inheritance: If the method is inherited, ensure that the child class is correctly set up to access the parent class's methods.
  Check Parameters: Ensure that the parameters you are passing to the method match the expected signature.
