This field indicates whether the infocode allows multiple selection of its selection codes.
Selection infocodes that use the display option Lookup or Pop-up can allow multiple selection.
If multiple selection is allowed, you can set minimum and maximum restrictions on codes that are selected in response to the infocode. For each selection code you can set a maximum on how many times it can be selected in response to the infocode (for example, when the code should only be selected once).
For more information see the Infocode table.
