Using date present as Headers(Columns)

[Pulkit_Thukral]

Hi All,

I have a requirement where the data is in the below format:

Node	12-Nov	13-Nov	14-Nov	15-Nov	16-Nov
1	success: 1	success: 1	success: 1	failed: 1	failed: 1
2	success: 1	success: 1	success: 1	failed: 1	failed: 1
3	success: 1	success: 1	success: 1	failed: 1	failed: 1
4	success: 2	success: 2	success: 2	failed: 1	failed: 1
5	success: 2	success: 2	success: 2	failed: 1	failed: 1
6	success: 1	success: 1	success: 1	failed: 1	failed: 1
7	success: 1	success: 1	success: 1	success: 1	success: 1
8	success: 2	success: 2	success: 2	success: 2	success: 2
9	success: 3	success: 3	success: 3	success: 3	success: 3
10	success: 3	success: 3	success: 3	success: 3	success: 3

As you may notice DATE is present as Column Header.

Now requirement is to pick out only last 2 dates i.e. 15th Nov and 16th Nov from above data and then check its content :

if last 2 dates have '*Failed*' as the value ,then that node will be considered as a faulty and a report would be generated for such nodes.

From above data,following should be the output in qlikview:

Node	15-Nov	16-Nov
1	failed: 1	failed: 1
2	failed: 1	failed: 1
3	failed: 1	failed: 1
4	failed: 1	failed: 1
5	failed: 1	failed: 1
6	failed: 1	failed: 1

How can this be done in qlikview ?

May be like in attached.

You can use Set Analysis in your expression to limit to the last 2 dates and only where it is failed. So it will be something like this

maxstring({<Date={'>=$(=max(Date)-1)'},Data={'failed: 1'} >}Data)

Hi Tresesco,

How are you taking "Date" Field in the data ?

[tresesco]

In crosstable() third parameter is number of fields qualifies . And the default is 1. That means here your first field is being picked silently. Learn about crosstable().

Hi Tracy,

Date Range would have to be the Primary Measure for calculation.

Example:- Another report- last 5 days Failure report would have only those Nodes listed where last 5 days data is present as Failed .Even is the ratio is 4:1 where last 4 days are Failure and last 5th day is a success, then also that node will be excluded from the list.

Not sure if this is covered in your expression ?

Hi,

maybe one solution could be also:

If(Max({$<Date={"=Date>=Max(Total Date)-1"}>} NodeState like '*failed*'), 'faulty', 'ok')

tabTemp:
CrossTable (DateTemp, NodeState)
LOAD * FROM [https://community.qlik.com/thread/240229] (html, codepage is 1252, embedded labels, table is @1) Where Node;
Join
LOAD Distinct
    DateTemp,
    Date(Date#(DateTemp&Year(Today()),'DD-MMMYYYY')) as Date
Resident tabTemp;

hope this helps

regards

Marco
