Link Table issue

[#1]

Hi,

I got the situation to connect 2 fact tables.

I have a fact table for transactions on day level(Invoice Date as DateKey) and also have a budget table on month level. Finally, I have a calendar table which has the fields DateKey and Month to join to both fact tables.

i do have one common field Vendor, to connect both Fact tables.

What should my link table look like to make this possible in Qlikview?

Thanks a lot in advance.

Hi,

You have different solutions, one is creating a pivot table in charge of connecting all the tables of your model.

For example, your table transaction will not contain any direct reference to the date and the vendor but a key composed of the both information (just concatenate the two field with a separator in between). This key will be present in the pivot table too. Your budget table will have a key composed of month and vendor.

So, your pivot table will have a key to join to transaction (date+vendor), a key to join to budget (month+vendor), a key to join to the vendor table, a key to join to the calendar table (DateKey).

QV will handle properly the cardinality.

Vincent

Hi Vincent, Thanks for your reply.if you don't mind, could you please explain a bit more clearly(don't have much idea on modelling)?say for example, i got 4 tables as below:

TRANS-Table:

Datekey,

Vendorkey,

Revenue.

VENDOR-Table:

Vendorkey,

Vendor-Info.

BUDGET-Table:

Month,

Budget.

CALENDAR-Table:

Datekey,

Month.

So, do i need to populate my pivot table with four columns?

Thanks.

Here is an example :

tmpTRANS:
Load * Inline [
DateKey, VendorKey, Revenue
40909, v1, 150
40910, v2, 200
40918, v1, 175
40942, v2, 240
40953, v1, 230
40973, v3, 1500
40984, v2, 90
] ;
VENDOR:
Load * Inline [
VendorKey, VendorInfo
v1, vendor1
v2, vendor2
v3, vendor3
] ;
tmpBUDGET:
Load * Inline [
Month, VendorKey, Budget
201201, v1, 200
201201, v2, 200
201202, v1, 300
201202, v2, 350
201202, v3, 400
201203, v1, 310
201203, v2, 320
201203, v3, 2000
] ;
tmpCALENDAR:
Load * Inline [
DateKey, Month, MonthName
