Max child value dependent on max date

irene.stewart159031

I have two columns a returned date and a recorded level.  The maximum recorded level is dependent on the maximum date.  The value will sit in the parent row.   Currently I have =MAX(CHILDREN()) in both columns.  Can this be done using Children or Parent references or is an IF statement required.  First time on the community so hope this is descriptive enough.

How exactly is the level dependent on the date?

We have continual monitoring but earlier recordings may have a higher level number.  From the example below I need to show the highest recording on 30/12/15 which is 210.  The 210 then dictates the frequency and date of repeat monitoring and is used in another formla.  Initially latest recordings were to replace old but this has changed so need to change =MAX(CHILDREN()) in level column to be dependent on the latest date.  Hope this make sense.  

30/12/15    210

30/12/15    180

03/06/15    320

03/06/15    540

It doesn't, but it may be because is 10pm on a Friday night.

Are you looking for the Max of the date (Dec 30, 2015) -- ie the most recent date and then the max level recorded on that date?

If so, then in the Date column, keep your MAX(CHILDREN())

In the Level column, use this formula (change [Date] to you Date column name

=MAX(COLLECT(CHILDREN(), CHILDREN([Date]@row), [Date]@row))

I hope this helps.

That's what I'm reading...
