Hello Experts,

Need your help in the below requirement,

1Feb-19Jun-19

 

I want the result to be like this in the End table. Is there any way we can do this in Back end.

Try this:

Data:
LOAD
    Project,
    Date#("Allocation Months",'MMM-YY') As "Allocation Months",
    Hrs
FROM [lib://Qlik]
(html, utf8, embedded labels, table is @1);

Interval:
LOAD
    Project,
    Date#("AllocationStart",'MMM-YY') As Start,
    Date#("Allocation End",'MMM-YY') As End
FROM [lib://Qlik]
(html, utf8, embedded labels, table is @2);

_tmp:
NoConcatenate
Load *
Resident Data;
Left Join IntervalMatch ("Allocation Months", Project)
Load Start, End, Project 
Resident Interval;

Drop table Data, Interval;

Final:
Load Project, Start, End, Sum(Hrs) As TotalHours
Resident _tmp
Group by Project, Start, End;

Drop table _tmp;

Result:

If you don't want the project with out start and end (not in the interval table), just change the Left Join to Inner Join.

I also attached a demo app for you.
