• What is the cause and solution for SAP error message B1204 - Method & has already been defined in the model view & ?

  The SAP error message B1204 indicates that there is a duplicate method definition in the model view. This typically occurs in the context of Business Object Modeling or when working with Business Process Management (BPM) in SAP.
  Cause:
  The error arises when:
  
  A method with the same name has already been defined in the model view you are working on.
  There may be a naming conflict due to the method being defined in multiple places or being inherited from a parent class or interface.
  
  Solution:
  To resolve the B1204 error, you can take the following steps:
  
  
  Check for Duplicates:
  
  Review the model view to identify if the method is already defined. Look for methods with the same name in the same context.
  
  
  
  Rename the Method:
  
  If you find that the method is indeed duplicated, consider renaming one of the methods to ensure that each method has a unique name.
  
  
  
  Review Inheritance:
  
  If the method is inherited from a parent class or interface, ensure that you are not trying to redefine it in a subclass or implementation. If you need to override it, use the appropriate syntax for overriding methods.
  
  
  
  Check for Multiple Implementations:
  
  If you are working with multiple implementations or versions of a model, ensure that you are not inadvertently defining the same method in different places.
  
  
  
  Clear Cache:
  
  Sometimes, clearing the cache or refreshing the model view can help resolve issues related to stale data.
  
  
  
  Consult Documentation:
