  Cause:
  The error message "Table count failed for preselection table &1" suggests that the system encountered a problem when trying to count the entries in the specified preselection table (denoted by &1). This could be due to several reasons, including:

  Database Issues: There could be issues with the database itself, such as connectivity problems or corruption in the table.
  Configuration Errors: Incorrect configuration settings in the migration tool or the preselection table could lead to this error.
  Authorization Issues: The user executing the migration might not have the necessary authorizations to access the preselection table.
  Data Volume: If the table contains a very large number of entries, it might lead to performance issues or timeouts.
  
  Solution:
  To resolve the CNV_OM_PRESEL119 error, you can take the following steps:
  
  
  Check Table Locking:
