Qlik Sense: Fetching data into fact table with filtered queries

[vaisgaard]

Hi,

I want to be able to build a fact table in Qlik Sense, where I collect data from different data sources. When fetching data from the data sources I want to limit the queries to the base structure of my fact table to limit data to a minimum.

Example:

Base structure of fact table

user_id	name
scjo	Scarlett Johansen
brpi	Brad Pitt
toha	Tom Hanks
anjo	Angelina Jolie
mada	Matt Damon

Sales table

user_id	sales
scjo	553
toha	625
anjo	125
brpi	485

Budget table

user_id	budget
scjo	500
brpi	700
toha	300
anjo	150
mada	250

Sales meetings table

user_id	meeting_date
brpi	2017-01-20
brpi	2017-02-03
toha	2017-03-10
anjo	2017-03-22

The source tables will in reality contain a lot of data on other user_ids, so I need to filter on only the employees in my fact table.

How to do this?

Hope you guys can help.

I think KEEP is what will help you in this scenario

Look at the example on using keep here

For Example try below

FACT

LOAD * inline [

user_id	name
anjo	Angelina Jolie
brpi	Brad Pitt
mada	Matt Damon
scjo	Scarlett Johansen
toha	Tom Hanks

];

INNER KEEP

table2

load * inline [

user_id
anjo
brpi
mada
scjo
toha

];

Drop table table2;

after this you will only have FACT data for ID's specified in table2
