This activity is used to add or remove variables from the
system. You can also view the list of variables that can be used in formulas.
All variables are user defined. Therefore, any variable that is to be used in
formulas should be entered in advance.
Note that you can add or delete variables from the system, and also modify the
description of the variables. However, once the record is saved, the variable
name cannot be modified.
The units of measure must have been defined in IFS/Application Base Setup.
As a result of this activity, variables will be created and saved.
