A formula is inserted into the structure of an MTM-1®, MTM-2®, or MTM analysis in the same way as into another analysis. Formulas can be used in sections.
If there are no values / default values in the formula for the parameters, the row is highlighted in red and the user receives a corresponding message. Otherwise, the time value in the structure row is the result of the default values.
Formula with missing default values
The formula parameters (values and coding) can be entered using the context menu or the Formula parameter button in the Structure ribbon.
Structure - calling up the formula parameters
The Calculate button is used to determine the result, which is written into the structure using Apply and becomes part of the total time of the element.

Element variables and formulas
Variables of elements can also be used as formula parameters.
If variables are maintained in the "Variables" tab of the element and a formula is linked that uses an identical variable as a parameter, this variable is automatically entered as a formula parameter when you insert the formula into the element. You can manually override the variable at any time in the "Formula Parameters" dialog box.

If a formula is already in use in an element and the variables from the Variables tab are to be used subsequently, you can enter the variables manually in the Formula parameters dialog. |
Value lists can also be created in formulas. If such a formula is used in an analysis, the desired parameter can be selected from the existing value list in the "Formula parameters" dialog.
