Cause

  2. Click the Editor tab.
  3. Update the 'Jet Engine max # of records to calculate' value. This value can be any number larger than the number of records in the current dataset. For example, if the dataset has 250,000 records, set the value to 300,000.

    Note:
    This step requires ADMINISTRATIVE access permissions.

  4. Close the ArcMap Advanced Settings window.
  5. Paste the feature class again.
