Changes

<p>Before a data entry form can be approved, you must decide whether the item records in the data entry form create new item records, update existing item records, or are associated with existing item records of different item types. This process is called ''reconciliation''.</p>

<p>Data entry form item records can also update existing item records. Updates to existing item records can either replace an existing item record or combine certain item record attributes. When an existing item record is replaced, the summary of the existing item record is replaced with the data from the new item record. When an item record in a data entry form is combined with an existing item record, certain item record attributes are overwritten with the data from the new item record while other item record attributes are combined. Refer to the [[Reconcile by Updating an Existing Item Record]] for more details on which item attributes are combined for each item.</p>
