Why "IT0034 - Corporate Function" should have a Time Constraint 2?
Time constraint '2' means that record may include gaps but no overlappings. However in Infotype 0034 "Corporate Function" the time constraint functions for the Infoytpe and sub-types.
This means that for the same sub-type no overlapping entries can be mantained but for different sub-types it is possible to save overlapping records.
