The cells in the grid have different colors. White grid cells denote that the user can enter data, green cells mean that 
the data is automatically calculated by the NAIIS application, light blue cells signify that dat a are automatically 
copied from a different node (for  example in 1.B.1.a.1.i), and yellow cells mean that a default value (for example, 
fraction of carbon stored in reference approach) is provided. Where the cell is grey, no input is necessary. (figure 24) 
In the energy sector, users are provided a dropdown list to select a unit in reporting t he consumption and production 
of fuels. This is marked with .

4.4	Data	input	
Data can be entered into the white grid cells only. It is also possible to copy and paste data from one cell to another 
by using the shortcut keys ‘ Ctrl + c ’ to copy and ‘Ctrl + v ’ to paste. Each value entered is automatically saved . 
When the data is entered, it is first shown in bold, and then changes to normal font indicating that the value has been 
saved. Saving occurs immediately  (usually within 1 second), but in case the system becomes slower, the user 
should wait until data are shown in regular font before exiting the grid . Otherwise, the data entered will not be 
saved. 
As mentioned in the previous section,  default values are provided for some par ameters (yellow cells in the grid).  
These values can be overwritten if the Party has more accurate data. 
Note: Data that has been entered will be automatically saved. 
 
4.5	Add/delete	new	nodes	–	user	defined	source	categories	
4.5.1	Add	new	nodes	
New nodes, for example, can be added to  the navigation tree in order to add ei ther a category, a fluorinated gas (F-
gas), a fuel, a livestock type, or a subdivision in the LULUCF sector. 
User-defined items can be added for: 
 Categories indicated as “Other (please specify)” 
 LULUCF subdivision 
 User-defined fuels
