When importing parameter values, the index lists of the model determine which data is imported. This means that if a model has three contaminants defined (Candy, Soda and Cigarettes) and the parameter tooth_ache_factor is imported, only values for Candy, Soda and Cigarettes will be imported even if the Material index list of the database also contain contaminants Rum, Gasoline and Gravel.
It is also important that the indices are spelled the same way in Ecolego and in the database/Excel. Therefore it is practical (and time saving) to import dependencies from the database or an Excel file rather than creating them manually.
To import index lists from Excel, select
File|Import|Import Index-lists from Excel… and select a file from which to import.
File|Import|Import Index-lists from Database…. Index lists will be imported from the currently selected database project.
Select lists and use the arrow buttons to move add them to the model.
Click Import in the bottom of the window to import the dependences.
