Identify inflow of new lines in a table

[RubenMoreno]

Dear all,

I have the following question, you might be able to support.

I load a table once a week in Qlik Sense including new data linked to that week. E.g.

Column 1 / Column 2

ValueA     /  CW02

ValueB    /   CW02

ValueA    /   CW03

ValueC    /   CW03

I want to add a new column "Column 3" when loading the data to identify if the value in "Column 1" has been already provided in a previous week or not. E.g.

Column 1 / Column 2 / Column 3

ValueA      /  CW02         / NEW

ValueB     /   CW02        / NEW

ValueA     /   CW03        / NOT NEW

ValueC    /   CW03         / NEW

As "ValueA" was already in the table in CW02, then when loading the data in CW03, it should be highlighted as NOT NEW in "Column 3" for CW03.

I appreciate if you could support with this. Thanks you in advance.

Best regards,

Ruben

Hi,

If I understood correctly , maye be :

Data:

load *,if(Exists([Column 1]),'NOT NEW','NEW') as [Column 3] inline [
Column 1 / Column 2

ValueA     /  CW02

ValueB    /   CW02

ValueA    /   CW03

ValueC    /   CW03
](delimiter is '/');

output :

HI

this script should help you 

OldData:
load *,
     if(Exists([Column 1]),'Old','New') as [Column 3];
load * inline [
Column 1,Column 2
ValueA,CW02
ValueB,CW02
];

NewData:
Load *,
      if(Exists([Column 1]),'Old','New') as [Column 3];
load * inline [
Column 1,Column 2
ValueA,CW03
ValueC,CW03
];

Hello Taoufiq,

I tried your suggestion and my problem is that the code identifies all lines as "Old"

The example I provided is a very simplyfied version of my problem. I will provide further details.

My Qlik Sense App is reading the data from an Excel file that it is weekly updated. Then I execute "Load data" and with this, old and new lines of this excel are re-loaded. The code would look like this:

[Weekly Report]:
LOAD
     [Prog Code],
     [Customer Version],
     ...
     [CW],
     [Key]
FROM [lib://.../Weekly BFE discrepancy monitoring.xlsx]
(ooxml, embedded labels, table is [Weekly Report]);

My objective would be to compare the values in  [Key] for the latest week with the content of  [Key] for previous weeks and identify  if they are "new" or "old".

Thank you in advance.

Best regards,
Rubén
