In Business Analyst Online, when a color-coded map is created for a defined area by selected geography, the geography graphic appears in the exported image or PDF while it's not visible on the project's map or the preview.
This issue is not reproducible in the latest version of ArcGIS Business Analyst Web App. When limiting the extent of a color-coded map to a site and then creating a PDF or an image, the output does not display the shaded site overlaid on top of the symbolized geographies. If the issue persists, contact Esri Support Services.
