Data Mapping rules help you understand how data is gathered and displayed.
Data mapping is a useful tool for viewing different levels of data in a model. Because the model hierarchy can be mapped at different levels, it is important to know from where the data is being collected to accurately interpret the results.
Additionally, you should also know how file attachments affect the report results.
A report is generated using all of the files in the current model, including attachments. As a result, the chart may not have a 1:1 correlation with the files displayed in the canvas.
For example, a pie chart slice may indicate that a large percentage of files is currently in the Work in Progress (WIP) state. However, when mapping the data onto the model, only a small number of files are color coded to the WIP slice. This difference in display is because the slice is taking into account the attached files as well as the part files but only the part files are visible on canvas. You can view the full report to see a complete list of files that make up a pie slice.
When a report is generated, the reporting system evaluates the files without knowledge of their relationships. The resulting chart represents actual flat data. Since a model has several levels to it, you have the option of mapping your data as three different levels to better understand the report data. This versatility allows you to examine model data at the parts level, the assemblies level, and the first children level. By examining all three levels, you will have the most complete picture of the report results.
Leaf Node mapping is the most granular view of the model. Only parts within assemblies are mapped. This level is used most often early in a project to see where components are in the development process.
All Assemblies mapping provides a perspective of the report results as they relate to the assembly level and first level parts. The color of an assembly determines the color of its parts but subassemblies are assigned their own colors.
First level children mapping is the least granular view. All parts and assemblies within each first level child are given the same color as the first level child.
