This typically occurs in the context of data replication or data transfer processes, such as those involving SAP Data Services or SAP Landscape Transformation (SLT).
  Cause:

  Solution:
  To resolve the EDEREG656 error, you can take the following steps:
  
  
  Check Existing Time Slices:

  Review Configuration:
  
  Review the configuration settings for the data exchange process to ensure that they are set up correctly. Look for any parameters that may be causing the creation of duplicate time slices.
  
  
  
  Check for Concurrent Processes:
