How can we apply break back to the line item that is having filter, for example I have one list with list items 1,2,3,4. In a module I will use this list as a dimension and will apply filter which will show only 1,2. now if i enter a value on parent then it has to split between 1 and 2, but it is happening like splitting between 1,2,3,4.
You can use breakback and DCA to control which cells are used when distributing the value. Essentially mimicking the "hold" feature. This is a workaround for using brakback in NUX, where we can't select the cells which should hold their value when doing adjustments. You should just use the filter item as the DCA write input.
But If I understand correctly, depending on the filter you would like the break back to split the total only in the available cells irrespective of the value of the other items, that it indeed can't do, because the sum of all the values have to equal to what you put in the total. The only workaround I can think of is always having a total of 0 before you input in your cells, but don't think it's practical.
