• What is the cause and solution for SAP error message RSDHA377 - Generated ADMP class '&1' can only have the methods '&2' and '&3' ?

  The SAP error message RSDHA377 indicates that there is an issue with the definition of an ABAP Data Mining Process (ADMP) class in the context of SAP BW (Business Warehouse) or SAP HANA. This error typically arises when the methods defined in the ADMP class do not conform to the expected methods that are allowed for that class type.
  Cause:
  The error message suggests that the ADMP class you are trying to use has been defined incorrectly. Specifically, it indicates that the class can only have certain methods, which are specified in the error message as '&2' and '&3'. This usually happens due to one of the following reasons:
  
  Incorrect Method Definition: The class may have methods that are not permitted for its type.
  Incompatibility: The methods defined in the class do not match the expected interface or abstract methods that need to be implemented.
  Configuration Issues: There may be configuration issues in the BW or HANA system that are causing the class to be recognized incorrectly.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Class Definition: Review the ADMP class definition in the ABAP Workbench (transaction SE80 or SE24). Ensure that only the allowed methods (as indicated in the error message) are defined.

  Implement Required Methods: Ensure that the required methods (those listed in the error message) are properly implemented in the class.
  
  
  Check for Inheritance: If your class is inheriting from a parent class, ensure that the parent class is correctly defined and that you are not overriding methods incorrectly.
  
  
  Transport Requests: If the class was recently transported from another system, ensure that all dependencies and related objects were also transported correctly.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to ADMP classes for any specific requirements or changes in newer versions.
  
  
  Testing: After making the necessary changes, test the class to ensure that it functions as expected without generating the error.
