Derived tables with prompts - based universe

Question

why can't I use derived tables with prompts - based universes on Dashboard Design 4.0? I mean I can add to Dashboard Design data coming from a universe like that but the prompts don't show in the query panel in Dashboard Design. Could it be becuase my universe was created first as an unv and then I transformed it to unx?

Answer 1

Good day Yuvraj,
Thank you for your response.
Basically, I have 2 classes based on physical tables:
Product (P); and
Time/Calendar (T/C).
Two classed based on derived tables:
Stock on Hand (SoH); and
Stock Movements (SM)
The derived tables SQL code selects (Quantity and Selling Price) from the SoH table and joins to the T/C table with conditions and a Where clause to restrict the data output to the last 2 months (the same applies to the SM derived table).
Example code below:
SELECT  q.sm_table _no, q.tim_cal_no, q.quantity, q.selling_price
FROM    tim_cal_table p,
              sm_table q
WHERE  q.tim_cal_no= p.tim_cal_no
AND        p.day between to_char(sysdate - 60,'DD/MON/YY') and to_char(sysdate - 1,'DD/MON/YY');
Now, the SoH table and the SM table are joined (in the universe schema) to the P table and T/C table using Primary Keys (which are shared by all the tables - physical and derived i.e. foreign keys on the SoH and SM tables used in the derived tables).
Now to answer your questions:
Do you get data in case you take objects only from derived table class?NO
Does the columns used to join physical table and derived table has matching values? YES. I mean to say is the join getting satisfied? YES. Checked Universe Integrity - structure, objects, joins, conditions, loops, context and cardinalities - everything is OK.
Adding to this, is the data type same for both the columns (on which join is set) or is there any typecasting required? YES - checked the data types of the primary/foreign keys that join the tables and they all match, except for one on the SM table -  the foreign key has 6 set for precision (instead of 5 as per the other columns), however the data type is Numeric so this shouldn't be an issue.
I hope this helps to clarify the nature of the problem.
Thank you.
Regards,
