  The SAP error message CNV10310762 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that the system expects a selection of a block of data (usually a range of records) but has detected that more than two lines (or records) have been selected. 
  Cause:
  The error is caused by the selection of multiple records in a way that does not conform to the expected input format. Specifically, the system is looking for a clear start and end point for a block of records, but it has detected that the selection is ambiguous or exceeds the expected format.
  Solution:
  To resolve this error, you can follow these steps:

  Consult Documentation: Refer to the SAP documentation or help resources related to the specific migration or conversion tool you are using. There may be specific guidelines on how to select records properly.
  
  
  Test with Fewer Records: If you are still encountering issues, try testing the selection with a smaller number of records to see if the error persists.
