• What is the cause and solution for SAP error message DRF_DDIC001 - Function not possible because more than one row is selected ?

  The SAP error message DRF_DDIC001 indicates that a function cannot be executed because more than one row has been selected in a context where only a single row is expected. This typically occurs in the context of data replication or data transfer processes, particularly when using the Data Replication Framework (DRF) in SAP.
  Cause:
  
  Multiple Entries: The most common cause of this error is that the system is trying to process multiple entries (rows) when it is designed to handle only one. This can happen if the selection criteria used in a query or function call are too broad, resulting in multiple records being returned.
  Configuration Issues: There may be issues with the configuration of the data replication settings, leading to unexpected results.
  Data Integrity Issues: There might be duplicate entries in the source data that are causing the function to select more than one row.
  
  Solution:
  
  Refine Selection Criteria: Review the selection criteria used in the function or query. Ensure that it is specific enough to return only a single row. This may involve adding additional filters or conditions.
  Check Configuration: Verify the configuration settings in the Data Replication Framework. Ensure that the settings are correctly defined to avoid selecting multiple rows.
  Data Cleanup: If the issue is due to duplicate entries in the database, perform a data cleanup to remove or consolidate duplicate records.
  Debugging: If you have access to debugging tools, you can trace the execution of the function to identify where the multiple rows are being selected and adjust the logic accordingly.
  Consult Documentation: Refer to SAP documentation or notes related to the specific function or process you are working with for any additional guidance or known issues.
  
  Related Information:
