In case you select the data type Selection or Multi Selection you enter the selection options in the text box underneath. One line consists of a clear key and the display name, separated by semicolon.
The key is necessary as the selection fields of third party systems often use numerical values instead of display names. Thus, the key facilitates the export/import. In addition, keys offer the advantage of retrospectively editing the display name at any time without losing data or having to manually correct old data records, as long as the key remains the same. You can freely choose the key, i.e. it can be a number or text. In case you do not enter a key, portatour® will automatically assign it, i.e. in alphabetical order.
On windows computers you have to press the Ctrl key in order to select several elements.
