In a hierarchy some entities are changing from 90% Subsidiaries to Not Consolidated method and 0% Ownership, the same entities are consolidating in a 100% in other hierarchy, FCCS generates disposals and acquisitions, in Periodic for Proportion is calculating zero, but in YTD is not showing the reversal.

I changed a consolidation method and proportion, some entities were consolidating in an old hierarchy and the new hierarchy are consolidating in 100%, in this case generates disposals in the old hierachy, and acquisition in the new hierarchy. FCCS_Proportion are calculating zero, at total level, Periodic view is showing reversal, but in YTD are not calculating this reversal, because periodic is zero.
