==Field Reports and Current Views==
All mine action information is entered into IMSMA<sup>NG</sup> via a field report, a data entry form used to collect information about an item. When a field report is completed, it is either reconciled to an existing item (that is, it is determined to be information about an item that already exists in IMSMA<sup>NG</sup>) or it is reconciled as new (that is, it is determined to be information about an item that does not already exist in IMSMA<sup>NG</sup>).

With this approach, users can collect and store multiple field reports about the same item over time so that the entire history of the item is preserved in the system. The approach also provides a complete audit trail of all changes made to any mine action information so that information managers can answer the question, "What did we know and when did we know it?"
