Cause

In the parts database to be checked, a part was found at which a value was entered for the ERP number property which already exists for the same property at another part. This may have been caused by editing via the EPLAN API.

Solution

1. In the message management dialog mark the line with the message and select the Properties popup menu item.
   
   The Parts management dialog is opened, the respective part is already marked in it.
2. Bring the Properties tab to the front.
3. In the property table open the hierarchy level General.
4. Remember the entered value for the ERP number property.
5. Repeat this at all other parts for which the message was output.
6. Enter different values for the ERP number property at all parts.
7. Close the parts management, save the modified data, and carry out a parts synchronization.
8. If required, start a new check run.
