section access data reduction

[cedfoning]

Hello, i'm new to qlik sense, and i have the following issue. 

I want to implement a section access in my qlik sense app. 

i have the following : 

1) in my QMC, i have these users :

BPC\User1,BPC\ User2, BPC\User3

i have created 3 AD group for the 3 users : 

ADGroup1 for user1, 

ADGroup2 for user2, 

ADGroup3 for user3. 

Each user is associated to an organisation. this info is in a table in the datamodel. the field name is "orga"

User1 & User2 are in orga1

User3 is in orga2

Now, i want to implement section access with the above infos. 
Each user must only see the data corresponding to his organisation. 

thanks for your help

I'd do something like this. Remember to save a copy of the app prior to implementing this and check the "Initial Data Reduction Based on Section Access under" settings>Document Properties>Opening.

Table

ACCESS	NTNAME	PASSWORD	ORGA
ADMIN	BPC\admin	*	*
USER	BPC\User1	*	orga1
USER	BPC\User2	*	orga1
USER	BPC\User3	*	orga2

Script

SECTION ACCESS;

SECURITY:
LOAD LTRIM(UPPER(ACCESS)) AS ACECESS,
LTRIM(UPPER(NTNAME)) AS NTNAME,
LTRIM(UPPER(ORGA)) AS orga

FROM SectionAcessTable

SECTION APPLICATION;

Hello, thanks for your reply

Do i need to create the section acess table as above ? 
Like i said, the field "orga" is found in another table in the data model

The users are added via AD in the QMC. 

thanks

If so, only run the Section Access script under the Hidden Script
