Use this tab window to define the length and number of rows for different attributes. When a module is installed, a number of base logical units with attributes will be entered with the length and number of rows automatically stated. Both lengths and number of rows are, in this case, regulated by restrictions from the installed modules. You can only change values for the attributes you can search for, i.e., you cannot enter any new attributes in this window. The number of attributes in this window depends on which modules are installed.
