Hi everyone. Need some help with a lookup function in my inspection app.

I have a label with the current formula "

LookUp(TTDDefectCaptures,CompareDefect = ThisItem.CompareGameList).defectSubWeek"

This returns a week that an item was inspected. Since we are not clearing the data out, it stores each week that data was created. The week we are in is week 11, last week being week 10. The issue I am seeing is that the lookup will look for the oldest entry, or it will not see a new entry. So if I do an inspection today, the lookup will not see week 11 in the lookup formula. Ive messed with using First, but to no avail. Any help would be amazing, thank you!!!

hi @ckserra33 lookup will return the first value

Consider a tabe as datasource: Table({a:0, b:1},{a:0, b:2},{a:0, b:3})

a = yourItem

b= weeknumber

Lookup the latest weeknumber would be.

LookUp( Sort( Table( {a:0, b:1}, {a:0, b:2}, {a:0, b:3} ), b, Descending ), a = 0 ).b

yours

LookUp(

Sort(TTDDefectCaptures,CompareDefect = ThisItem.CompareGameList),defectSubWeek,Descending).defectSubWeek

)

hope it helps,

R

This sounds like it could be related to delegation. When you go to Settings > Data Row Limit , try increasing this to 2000. Alternatively, if your list could potentially increase to larger than 2000 rows, try to filter your list before you use lookup. Something like LookUp(Filter(TTDDefectCaptures, ______ = ___),CompareDefect = ThisItem.CompareGameList).defectSubWeek). Another option is to try sorting your list before you lookup so that you are querying the newer items first such as LookUp(SortByColumns(TTDDefectCaptures, "createdon", Descending),CompareDefect = ThisItem.CompareGameList).defectSubWeek

Thank you @techie-t and @rubin_boer for the quick responses!! I wound up using your solution snd sortbycolumns before the lookup, and it worked great!

Here is the formula, thanks again!!

LookUp(SortByColumns(TTDDefectCaptures,"createdon",Descending),CompareDefect = ThisItem.CompareGameList).defectSubWeek
