Just like any other time-series input, you can enter a time-series formula on the button for a Mapping input, in both Requirement and Mapping dialogs (or the expanded Requirements and Mappings dialogs). For example, you might wish to define the Mapping for the last Resource in a Function as the complement of the other Mappings. You can create references to the other Mappings by clicking on the respective Mapping buttons while editing the formula for the last Mapping – see 4.12 Creating formulae and internal references.
You will notice that the form of the reference created is as follows:
"Service 1".Requirements."Resource 1".Mapping
