Variable Tags provide a way to classify and provide useful metadata about the variables. Tags are displayed on the variable properties section of the variable edit screens. Each variable can have as many tags as desired, or none at all.
Adding Tags to Variables
Variable tags can be used to categorize variables. When running a projection, you can select specific tags to include or exclude as a way to filter which variables are executed during the model run. A common application for variable tags is to identify variables for a specific accounting basis such as US GAAP. This way you can specifically exclude or include all variables tagged US GAAP depending upon the applicability of this accounting basis to your projection. More info on projection inputs including variable tag inclusion and exclusion, can be found on the Projection Inputs article.
Whenever a variable is created, it has no tags initially. On the Formula Builder section of the variable edit screens, the variable will display a (No Tags) message.
Clicking on top of the (No Tags) message will load an editor where new tags can be added.
Clicking on the text box will display a list of all the tags that have already been created on the current model. You can select tags from this list by clicking on them or using the typeahead functionality to find one and pressing enter to select it. Or you can type a new tag to be added. Press enter after the end of each tag when creating new ones to indicate the end of the tag. Once all tags have been selected, press the checkmark button to save the tags to the variable.
