When running LoadBuilder the following errors appear.
"# ID(s) do not match any IDs in the model."
"Calculations failed due to…"
These dialogs could be appearing for a couple of reasons.
Scenario 1: Using a LoadBuilder method that uses a selection set for a layer.
The selection set(s) used in LoadBuilder are "selection based", which means it was created from a group of selected elements. If one or more of the elements have been deleted since creating the selection set then LoadBuilder will consider them missing and won't continue.
Scenario 2: Using a LoadBuilder method that uses a Shapefile for a layer.
One or more of the service area polygons are missing their corresponding element (the junctions used in the Thiessen polygon tool). This could happen if for example you deleted the junctions after creating the Thiessen polygon shapefile.
The selection set will need to be updated.
Try the following:1. Note the selection set(s) used in LoadBuilder when the dialogs appear.2. Open the Selection Sets manager.3. Double-click on the selection set, used in LoadBuilder, to select the elements in the drawing.4. Click the New icon in the Selection Sets manager, select "Create from Selection", then enter a name.5. Repeat steps 3-4 as needed.6. Try using LoadBuilder again with the updated selection sets.
Add the shapefile as a background layer to visually see if any of the corresponding junctions are missing. If you used a different method besides the Thiessen Polygon creation tool, it is recommended you use this to assure that the service area reflects the elements in the model.
