Hi Amit, You need to use the node for both. In FpML the recipient of the message needs to calculate the duration of the stub and compare it against the duration of a regular period in order to know whether it’s short or long. There is a short/long field available, in CalculationPeriodDates/stubPeriodType (values of StubPeriodTypeEnum = {ShortInitial, ShortFinal, Longinitial, LongFinal}) but it doesn’t support initial and final stubs at the same time. Hope this helps. Marc
