+* **Additional Notes**
+
+   * **Import Scheduled!**
+
+If you have more than 1000 records in your file, your import will be scheduled immediately and an email notification will be sent to you after the successful import.
+
+  * **Data Corruption Error**
+
+This error shows up when the import is interrupted for various reasons like crashing in between or canceled by a user etc. This error indicates that the import table still has records to be imported into the system, but all the information related to the import (like mapping, default values, merge criteria) are all lost. So these records can no more be imported and the user needs to clear this data before starting any other import.
+
+  * **Import Locked Error**
+
+This error will be displayed if the import has been already started on the same module by any other user in Vtiger CRM. The details of the module, the user, and the time at which the Import has been locked is detailed within the error message itself.
+
+  * **Import Interrupted Error**
+
+If an Admin user is performing import and if a non-admin user tries to start an import on the same module, he will get to see the Import Locked error. If a non-admin user is doing the import, and Admin user attempts to import the same module, same time, he can be able to see the status of the current import and he will even have powers to cancel the current import; Consequently, the Import Interrupted Error will be displayed to the non-admin user.
+
+  * **Heads Up!
+
+   **1.** If you would start importing in one particular module, you cannot import records into the same or any other module in Vtiger CRM.
+   **2.** If you would trigger import on a particular module, neither you nor any other user in Vtiger CRM can import records into the same module. However, other users can import records into other modules in Vtiger CRM.
