Identifying missing entries

Hi,

I have a set of data below showing entries by staff from 2 Oct to 15 Oct and I need to use Qlik to show 2 things:

1. How many staff did not provide entries for 2 days or more (Ans: 2).

2. Show who are the staff who did not provide entries for 2 days or more (Ans: Staff 10 and Staff 1002).

Can anybody please advise? Thank you in advance.

Hi @Jarvay , for the fist one you can use:

=Sum(Aggr(If(Count(DISTINCT [Recorded On])<Count(DISTINCT TOTAL [Recorded On]),1), [Staff Name]))

and for the 2nd:

=Concat(Aggr(If(Count(DISTINCT [Recorded On])<Count(DISTINCT TOTAL [Recorded On]),[Staff Name]), [Staff Name]), ',')

Hi Rubenmarin,

Thanks for the advice! Sorry but I forgot to to add that the staff has to have missed providing inputs for consecutively 2 days before it is considered as a count. My bad...

Hi @Jarvay then it will be better to flag those records on script... and if the staff misses for 4 consecutive days it counts as 1, or 2 or 3?

// Cartesian of staff and dates
tmpStaffDates:
LOAD 
	 FieldValue('Staff Name', RecNo()) 	as [Staff Name]
AutoGenerate FieldValueCount('Staff Name');

Outer Join (tmpStaffDates)
LOAD 
	 FieldValue('Recorded On', RecNo()) 	as [Recorded On]
AutoGenerate FieldValueCount('Recorded On');

// Add values (the ones witout values will be null)
Left Join (tmpStaffDates)
LOAD [Staff Name], [Recorded On], Temperature
Resident TableDataName;

// Remove previous data table to keep the temporary as the data table
DROP Table TableDataName;

// Flag records
TableDataName:
LOAD [Staff Name], [Recorded On], Temperature,
  If(Peek([Staff Name])=[Staff Name] and IsNull(Temperature) and IsNull(Peek(Temperature))
    ,If(Peek(isGap)=0 and not IsNull(Peek(Temperature,-2)), 1, 0) //This is to flag only the first 2 days gap
    ,0) as isGap
Resident tmpStaffDates
Order By [Staff Name], [Recorded On];

// Remove temporary table
DROP Table tmpStaffDates;

Expression can be:

- Sum(isGap)

- Concat(DISTINCT {<isGap={1}>} [Staff Name], ', ')

Hi Rubenmarin,

A big thanks! Looks complicated for a beginner like me but will take some time to study the solution.

And if the staff misses providing inputs for 4 consecutive days, it should count as 1.
