Qlik Sense add same qvd table twice in Data Manager

Hi all

We have a data structure in which we refer to one table more than once. To make it simple, consider the following simplified example. Say we have a table with meetings, attendees and organisers (where the organiser can also be an attendee). Our normalised structure looks something like this (very simplified, but I think it explains the problem):

Meetings

MeetingIdDescriptionOrganiserStaffId
1Meeting 11
2Meeting 21

MeetingAttendees

IdMeetingIdAttendeeStaffId
111
212
321
422
523
624

StaffMembers

StaffIdStaffMemberName
1Tony Stark
2Peter Benjamin Parker
3Wade Wilson
4Steve Rogers

In my example above, I would like to know how self service users can add the StaffMembers table twice in the Data Manager (not in the Data Load Editor) so that it can be joined onto the Meetings table (StaffMembers.StaffId = Meetings.OrganiserStaffId) and also to the MeetingAttendees table (StaffMembers.StaffId = MeetingAttendees.AttendeeStaffId). The Data Manager does not create a new "bubble" when I add the StaffMembers table again so that I can associate it with the MeetingAttendees table as well.


In other words, when I add the three tables I get the following:

Three_bubbles.png

When I try to add the StaffMembers again then I don't get another bubble, the picture stays the same as above. I would like something like StaffMembers2 the picture below:

Four_bubbles.png

This is going to be a self service solution and thus I do not want to change anything in the Auto-generated section of the Data Load Editor. The users will only have access to the tables/bubbles and will be able to add them using the Add Data function in the Data Manager. I would prefer to only store a table once and not to copy and rename it. In my actual problem, the same table can be used up to four times and they can be quite big as well.

Any help will be appreciated.

Re: Qlik Sense add same qvd table twice in Data Manager

This is a great question that my team is curious on as well.

 

Most self service users we have tried to push into the data load editor have pushed back due to inexperience.  So we are trying to see how much data modelling can actually be done just with the data manager.

 

The example you provide is the same exact question I have received from multiple users when dealing with employee information.  For instance, a lot of them work with audit data.  So the fact table they might have would have several employee fields:

 

Issue Discovered By

Issue Resolved By

Responsible Manager

Responsible VP

 

All of these would be IDs rather than names, so adding on the names and other relevant info is where our users struggle since the data manager only lets you add the employee dimension table one time.

 

Any help is appreciated!
