• What is the cause and solution for SAP error message UJD_EXCEPTION256 - Selection overlaps with delta initialization &1 ?

  The SAP error message UJD_EXCEPTION256 indicates that there is an issue with the selection criteria used in a query or report that overlaps with the delta initialization for a data source. This typically occurs in the context of SAP BW (Business Warehouse) or SAP BW/4HANA when working with delta loads.
  Cause:
  The error arises when the selection criteria defined for a query or data extraction overlaps with the data that has already been initialized for delta extraction. This can happen if:
  
  The selection period includes data that has already been loaded in a previous delta initialization.
  The delta initialization process has not been completed properly, or there are inconsistencies in the data.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Selection Criteria:
  
  Review the selection criteria used in your query or data extraction. Ensure that the date range or other parameters do not overlap with the data that has already been initialized for delta extraction.
  
  
  
  Adjust Delta Initialization:
  
  If you need to change the selection criteria, consider re-initializing the delta load. This may involve:
  
  Performing a full load instead of a delta load if the data has changed significantly.
  Adjusting the delta initialization settings to ensure that the correct data is being captured.
  
  
  
  
  
  Monitor Delta Process:
  
  Ensure that the delta process is running correctly. Check for any errors in the delta load process that may have caused inconsistencies.
