This has the effect of limiting the subreport records to only those records that have a '''link''' to the guid or object passed from the main report.
===Direct Relationships===
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>

Direct relationships also exist when subsets of data are contained within an item. 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.
