When an error occurs during the import or export procedures, all modifications are cancelled and data is reverted to the state before the process was launched.
The only situation where the process continues executing even if an error occurs is when a dimension is not recognized. In this case, the procedure carries on with the next dimension.
When data integrity failures occur, the add-on leaves data validation to EBX®. For instance, if a relation is broken between two dimensions, the import procedure carries on and EBX® logs an error in the validation report.
