«Code Data» is one of the few concepts in CPM 4.3.1 that opens the door to consideration of NFRs (Non Functional Requirements)
They require attention because they should not be counted as data group or as transactions related to the data group: this can lead to entire chunks of a system to simply disappear from counting.
Changing scope/boundary might however bring the data group back into consideration, as they might be used in the new boundary also to directly implement a FUR.
