Normally the changing of a fixed variable into a value range variable is automatically detected. You can recognize this at the missing tree icon.

The values of the fixed variable FORM have been combined in a value range variable FORM.

Check the assignment by clicking into a value range field. The dialog box Enter value has to contain all possible values.

On the left side, in the old project, select the single lines one after another. On the right side, in the new project, the value of the value range field should be adjusted automatically.

If all mappings are correct, click on Verify all mappings .
