<p>Sub-report is reports within a report; thus, providing a way to generate a report that includes data on the target IMSMA Item as well as data on other IMSMA Items that are associated to the target IMSMA Item. Generally a sub-report is used in a situation where you have one or more sets of data relating to a single IMSMA item. A common use case would be a Location report with multiple details bands of different IMSMA items (Land, Activity, Accident, Victim, Education, and QM).</p>

<p>Regardless of what IMSMA data you’re including in your report and sub-reports, there are 6 basic steps to create a report with sub-reports:</p>

<p>The following section of the Advance Reports chapter discusses relationships between Items in IMSMA and also provides instructions on how to create a specific report/sub-reports.</p>

<p>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>

Certain items have subsets of data that are contained within them. For example, an education may have education details such as the education type, total audience, and percentage of women and men. The education details data requires the education to exist. Table 3. Parent/child relationships lists the items and the data subsets that depend on them.

Part 4 of this training module discussed direct relationships—relationships where the parent item must exist in order for the child item to exist. In this part of the training, you will learn about linked relationships. Linked relationships are optional relationships which may exist between items. Unlike direct relationships that are enforced during the IMSMA reconciliation process, links are optional. Accidents, land, activities, educations, and QMs may be related to one another via ''links''. For example, a victim may be associated to an accident in a particular land. If these relationships are known, IMSMA users may define these links while reconciling the Data Entry Form.

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.
