• What is the cause and solution for SAP error message CNV_00001174 - Indentical entry for source and target table ?

  The SAP error message CNV_00001174 indicates that there is an identical entry for the source and target table during a data migration or conversion process. This typically occurs in the context of SAP's data migration tools, such as the SAP S/4HANA Migration Cockpit or other data transfer processes.
  Cause:
  The error arises when the system detects that the same data record exists in both the source and target tables. This can happen due to several reasons:
  
  Duplicate Data: The source data may contain duplicate entries that are being mapped to the target table.
  Incorrect Mapping: The mapping configuration may be set up incorrectly, leading to the same record being processed for both source and target.
  Data Integrity Issues: There may be issues with data integrity in the source system, causing records to be duplicated unintentionally.
  
  Solution:
  To resolve the CNV_00001174 error, you can take the following steps:
  
  
  Check for Duplicates:
  
  Review the source data for duplicate entries. You can use SQL queries or data analysis tools to identify duplicates in the source table.
  If duplicates are found, decide on a strategy to handle them (e.g., remove duplicates, merge records, etc.).
  
  
  
  Review Mapping Configuration:
  
  Verify the mapping configuration between the source and target tables. Ensure that the mapping is set up correctly and that it does not inadvertently cause the same record to be processed for both tables.
  
  
  
  Data Cleansing:
  
  Perform data cleansing on the source data to eliminate duplicates or correct any data integrity issues before running the migration again.
  
  
  
  Test Migration:
  
  After making the necessary adjustments, conduct a test migration with a smaller dataset to ensure that the issue has been resolved.
  
  
  
  Consult Documentation:
