SAP Error Message - Details

• Message type: E = Error

• Message class: OO_SOURCE_BASED - WB - Class Builder - Messages for the source-b. Class Editor

• Message number: 033

• Message text: A method implementation cannot uniquely be determined

What causes this issue?

The class can't be separated into its different source parts (public-,
protected-, (package-,) private section or method implementation).

System Response

A warning will be sent and the changes won't be stored.

How to fix this error?

Please check whether the source contains the following statements:
<EX>CLASS <class_name> DEFINITION.</>
<EX>...</>
<EX>ENDCLASS.</>

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

<EX>CLASS <class_name> IMPLEMENTATION.</>
<EX> METHOD <method_name_1>.</>
<EX> ...</>
<EX> ENDMETHOD.</>
<EX> ...</>
<EX> METHOD <method_name_n>.</>
<EX> ...</>
<EX> ENDMETHOD.</>
<EX>ENDCLASS.</>
<EX>It is also important to check that the public-, protected-,
(package-) and private section are in the correct order.</>
<EX>The syntax check will help you to determine where the class
structure is insufficient.</>

• What is the cause and solution for SAP error message OO_SOURCE_BASED033 - A method implementation cannot uniquely be determined ?

  The SAP error message OO_SOURCE_BASED033 ("A method implementation cannot uniquely be determined") typically occurs in the context of Object-Oriented ABAP programming. This error indicates that the system is unable to determine which method implementation to call due to ambiguity, often arising from inheritance or interface implementation scenarios.
  Causes:
  
  Ambiguous Method Resolution: This error often occurs when a class inherits from multiple superclasses or implements multiple interfaces that define methods with the same name and signature. The system cannot determine which method to execute.
  Missing Method Implementation: If a subclass does not implement a method that is defined in an interface or superclass, and there are multiple potential candidates, the system may raise this error.
  Dynamic Method Calls: If you are using dynamic method calls (e.g., using CALL METHOD), and the method cannot be resolved to a single implementation, this error can occur.
  
  Solutions:
  
  Check Inheritance and Interfaces: Review the class hierarchy and interfaces to identify any
