You can modify both constant and tabular data.
Constant Data
You modify constant data by changing the value and/or unit of that data in the Properties pane. The value and unit together constitute one integral piece of information, or datum. The value is modified by selecting the cell in the Value column and typing in the new value. If available, modifying the unit converts the value to correspond to the new unit (see Units Menu). If the value entered is not in the acceptable range, it is indicated in yellow and causes the state of the Engineering Data cell to change to Attention Required.
Tabular Data
If the data is in a tabular format, it is indicated in the Value column ( ). This data is modified in the Table pane and each datum is a value and unit as one integral piece. The value is modified by selecting the cell in the variable column you want to change. If the value entered is not in the acceptable range, it is indicated in yellow and causes the state of the Engineering Data cell to change to Attention Required. The unit is shown in the header, and if available, modifying the unit modifies each datum for that variable to have the same unit (see Units Menu).
