Various Kinds of Subreports
==Various Kinds of Subreports==
<p>This section discusses relationships between Items in IMSMA and also provides instructions on how to create a specific report/sub-reports. The reports discussed so far in this training module have been based on a single data source. In this part of the training module, you will learn to create more complex reports that reference multiple data sources. Some items are dependent on the existence of another item. This type of relationship is referred to as a direct relationship. For example, an accident, land, activity, education, QM, or victim has a direct relationship to the location to which it is associated. The accident, land, activity, education, QM, or victim cannot exist unless it is associated with a location. This direct relationship is enforced in IMSMA via the reconciliation process.</p>

The process for creating a report on an item and its linked items is similar to the process for creating a report on items with a direct relationship. The item in the main report is the primary item for which you would like to find linked items. The sub-report would return the records for the particular item that is linked to the primary item. The key difference is the query used in the sub-report.
If you would like to report on different items that linked to the item in the main report, you may create a new sub-report for each linked item. For example, to create a report of land and the accidents and activities that are linked to those land, you would create the main report on land. This report would then contain a sub-report to list linked accidents, and another sub-report to list linked activities.
