==Field Reports and Current Views==

All mine action information is entered into IMSMAA <supb>NGfield report</supb> via a field report, is a data entry form used to collect record and store information about an item. When A <b>current view</b> is a field report is completed, it is either reconciled to an existing item (that is, it is determined to be summary of all the information collected about an item that already exists in IMSMAon field reports.<supb>NGReconciliation</supb>) or it is reconciled as new (that is, it is determined the process of assigning the information in a field report to be information about an existing item or creating a new item that does not already exist in IMSMA^NG)current view.

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?"

===Assigning and Linking===

 

<b>Assigning</b> refers to the assignment of an item to a location for the purposes of grouping information. All items must be assigned a location.

 

<b>Linking</b> refers to the association between items for the purposes of analysis. Linking is optional, for example, when linking clearances to minefields.

IMSMA^NG provides the capability to assign items to locations and create links between items, a function that shows the relationships between items and processes and that enriches the data collected. Assignments and links are defined during the field report approval process. An item is assigned to one location, which ties the item to the country structure and allows for reporting mine action data by area. The same item can then be linked to as many other items as necessary. In this way, IMSMA^NG supports the idea of linking hazard reductions to hazards, victims to accidents or any item to any other item. When used with item subcategories, linking adds a powerful capacity to implement an information workflow and create rich and useful data for decision makers. To ensure the integrity of this data, system administrators must clearly specify the kinds of links to track in IMSMA^NG. See [[Maintaining IMSMA]] for more on this topic.
