IHTM31194 | Assessing: COMPASS: calculations: calculations out of sequence
From HM Revenue & Customs · Inheritance Tax Manual
COMPASS runs through the calculations to raise in the order they are shown on the case record.
If you want to raise a calculation at a later assessment group without raising a calculation at the current assessment group, for instance B/NIOP and not A/NIOP,
do not press the Cancel button () as this will cancel all calculations you have raised so far and will not allow you to progress.
Instead,
raise calculations for all the assessment groups in the estate,
issue () the calculations you want to send out,
withdraw () the calculations you do not wish to send out.
