How To Fix OO380 - Regenerate the constructor to apply the superclass's parameters

SAP Error Message - Details

• Message type: E = Error

• Message class: OO - Class Builder/API

• Message number: 380

• Message text: Regenerate the constructor to apply the superclass's parameters

What causes this issue?

The constructor is inconsistent due to changes on the constructor's
parameters of the super class.
The number or type of the super class parameters is not the same as in
the sub class.

System Response

In most cases, this inconsistency does not affect the behavior of the
exception class. This is only an information message; it might be
necessary to adapt the constructor of the exception class.

How to fix this error?

In order to adapt the constructor of the exception class, execute the
following menu entry:
Utilities -> Cleanup -> Constructor -> Class
There is also the possibility to adapt the constructors for all sub
classes by executing the following menu entry:
Utilities -> Cleanup -> Constructor -> Subordinate classes

Procedure for System Administrators

• What is the cause and solution for SAP error message OO380 - Regenerate the constructor to apply the superclass's parameters ?

  The SAP error message OO380, which states "Regenerate the constructor to apply the superclass's parameters," typically occurs in the context of ABAP Object-Oriented programming. This error indicates that there is a mismatch between the constructor of a subclass and the constructor of its superclass. Specifically, it suggests that the subclass's constructor does not properly call the superclass's constructor with the required parameters.
  Cause:
  
  Superclass Constructor Changes: If the superclass's constructor has been modified (e.g., parameters added or changed), the subclass's constructor may not be updated accordingly.
  Missing Superclass Constructor Call: The subclass constructor may not be calling the superclass constructor correctly, which is necessary to ensure that the superclass is initialized properly.
  Parameter Mismatch: The parameters expected by the superclass constructor do not match those provided in the subclass constructor.
  
  Solution:
  To resolve this error, you should follow these steps:
  
  
  Check Superclass Constructor: Review the constructor of the superclass to understand its parameters and ensure you know what is required.
  
  
  Update Subclass Constructor:
  
  Open the subclass where the error occurs.
  Ensure that the constructor of the subclass calls the superclass constructor using the SUPER keyword.
  Pass the required parameters from the subclass constructor to the superclass constructor.
  
  Example:
  CLASS lhc_subclass DEFINITION INHERITING FROM lhc_superclass.
    PUBLIC SECTION.
      METHODS constructor IMPORTING iv_param1 TYPE string.
  ENDCLASS.
  
  CLASS lhc_subclass IMPLEMENTATION.
    METHOD constructor.
      " Call the superclass constructor with the required parameters
      SUPER->constructor( iv_param1 ).
    ENDMETHOD.
  ENDCLASS.
  
  
  Regenerate the Constructor: In the ABAP Workbench, you can regenerate the constructor for the subclass. This can often be done by right-clicking on the class in the Class Builder and selecting the option to regenerate the constructor.
  
  
  Check for Other Errors: After making the changes, check for any other related errors that may arise due to the changes made.
  
  
  Related Information:
  
  ABAP Documentation: Refer to the official SAP documentation for more details on object-oriented programming in ABAP, especially regarding class inheritance and constructors.
  SAP Community: Engage with the SAP Community forums for discussions and solutions related to similar issues.
  Debugging: Use the ABAP debugger to step through the constructor calls to ensure that the parameters are being passed correctly.
  
  By following these steps, you should be able to resolve the OO380 error and ensure that your subclass properly initializes its superclass.
