• What is the cause and solution for SAP error message CNV_CDMC_UCIA050 - Select only one row for extended program check ?

  The SAP error message CNV_CDMC_UCIA050 typically occurs during the execution of a program related to data conversion or migration, particularly in the context of the SAP Conversion Tools. This error indicates that the program expects only one row to be selected from a database table or internal table, but multiple rows were found instead.
  Cause:
  The primary cause of this error is that the program logic is designed to handle a single record, but the query or selection criteria used to fetch data returned multiple records. This can happen due to:
  
  Incorrect Selection Criteria: The WHERE clause in the SQL query may not be specific enough, leading to multiple records being selected.
  Data Integrity Issues: There may be duplicate entries in the database that violate the expected uniqueness of the data.
  Configuration Issues: The configuration settings for the data migration or conversion process may not be set up correctly, leading to unexpected results.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Review the Selection Logic:
  
  Check the code or configuration that is responsible for fetching the data. Ensure that the selection criteria are specific enough to return only one record.
  If necessary, modify the query to include additional filters or conditions.
  
  
  
  Check for Duplicates:
  
  Investigate the underlying database table to see if there are duplicate entries that should not exist. You can run a query to identify duplicates based on the relevant fields.
  If duplicates are found, you may need to clean up the data by removing or consolidating duplicate records.
  
  
  
  Debugging:
  
  If you have access to the ABAP code, you can set breakpoints or use debugging tools to trace the execution and see why multiple rows are being returned.
  Analyze the internal tables and data structures to understand how data is being processed.
  
  
  
  Consult Documentation:
