Standard AX data import & deletion

When using standard Dynamics AX 2009 import & export functionality for data migration, there's one thing that needs to be careful of - the default settings is deleting data before importing new data.

The deletion happens to the last two setup options:
> Clear table before inserting records
> Use definition group settings - "Delete and import"

This (deletion) is the default value on the table setup and during the import, unless it has been changed once and saved into usage data.

Unfortunately standard AX do the delete and import in two separate transaction.
Any error on import won’t rollback the transaction for the deletion.

Screenshot showing the transaction level, the deletion is in its own transaction.
DeleteAction is not executed as well, so no other table is affected.
