SAP Error Message - Details

• Message type: E = Error

• Message class: ILM_STOR -

• Message number: 661

• Message text: No class name available for interface &1, version &2, parameter &3

What causes this issue?

The interface &syst-msgv1& determines an implementing class. The version
specification is [&syst-msgv2&], the parameter has the value [
&syst-msgv3&].
A key cannot be determined for this value either in the table
TILMSTOR_CF nor in the class factory implementation.

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

System Response

The procedure is terminated.

How to fix this error?

This can be an error in the settings in table TILMSTOR_CF or an

• What is the cause and solution for SAP error message ILM_STOR661 - No class name available for interface &1, version &2, parameter &3 ?

  The SAP error message ILM_STOR661 indicates that there is an issue related to the Information Lifecycle Management (ILM) system, specifically concerning the storage of data. The message states that there is "No class name available for interface &1, version &2, parameter &3." This typically means that the system is unable to find a class that implements a specific interface for the given version and parameter.
  Cause:
  
  Missing Class Implementation: The class that is supposed to implement the specified interface is either missing or not properly registered in the system.
  Incorrect Configuration: There may be a misconfiguration in the ILM settings or the storage system that prevents the correct class from being identified.
  Version Mismatch: The version of the interface being referenced may not match any available implementations in the system.
  Transport Issues: If the system has recently undergone a transport of changes, the necessary classes may not have been transported correctly.
  
  Solution:
  
  
  Check Class Implementation:
  
  Verify that the class implementing the specified interface exists in the system. You can do this by using transaction SE80 or SE24 to search for the class.
  If the class is missing, you may need to create it or transport it from another system where it exists.
  
  
  
  Review Configuration:
  
  Check the ILM configuration settings to ensure that they are correctly set up. This includes verifying the storage settings and ensuring that the correct classes are assigned to the relevant interfaces.
  
  
  
  Check Versioning:
  
  Ensure that the version of the interface being referenced is correct and that there is a corresponding implementation for that version.
  
  
  
  Transport Check:
  
  If the issue arose after a transport, check the transport logs to ensure that all necessary objects were included and transported correctly. You may need to re-transport the missing classes.
  
  
  
  Debugging:
  
  If the issue persists, consider debugging the code where the error occurs to gain more insight into why the class cannot be found.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to ILM and the specific interfaces you are working with for any additional guidance or known issues.
  
  
  
  Related Information:
