• What is the cause and solution for SAP error message CNV20200762 - More than two lines were selected; select start and end of block ?

  The SAP error message CNV20200762 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 continuous block of data (start and end of the block), but more than two lines have been selected, which is not allowed.
  Cause:
  The error is caused by selecting multiple, non-contiguous rows or lines in a data selection interface where the system expects a continuous range. This can happen in various scenarios, such as:
  
  When trying to select multiple records in a table or a list where only a start and end record should be selected.
  When the user inadvertently selects rows that are not adjacent to each other.
  
  Solution:
  To resolve this error, follow these steps:
  
  
  Select a Continuous Block: Ensure that you are selecting a continuous block of records. Click on the first record you want to select, then hold down the Shift key and click on the last record in the block. This will select all records in between.
  
  
  Check for Filters: If you are using filters or search criteria, ensure that they are set correctly to display the records you need without selecting non-contiguous lines.
  
  
  Review Documentation: Check the specific documentation for the migration tool or process you are using. There may be additional guidelines or requirements for selecting data.
  
  
  Test with Fewer Records: If you are still encountering issues, try selecting a smaller number of records to see if the error persists. This can help isolate the problem.
