IF statement on same value

Mon, 07 Jul 2014 13:37:59 GMT

I have the same Prog_Id as seen in the example below:

UKCountry	Prog_Id	Rating	Date	Projection
UK	10	01/05/2014	1,401,000
UK	5478	11	11/10/2013	57,340,162
UK	5539	11	01/11/2013	9,103,812
UK	5560	11	25/09/2013	20,491,000
UK	5634	11	04/12/2013	27,411,600
UK	5634	8	04/12/2013	1,106,809
UK	5657	10	14/02/2014	6,476,215
UK	5665	10	26/03/2014	12,600,000
UK	5665	8	26/03/2014	2,140,016
UK	5669	10	09/05/2014	22,785,308

The difference is that it holds different rating values.

Country	Prog_Id	Rating	Date	Projection
UK	5634	11	04/12/2013	27,411,600
UK	5634	8	04/12/2013	1,106,809

So for example Prog_Id 5634 has the rating 11 and 8. But I want to filter this in the following manner:

If Prog_Id's are the same and IF the rating is > 10, then give me the projection value, IF NOT, give me blank.

Keep Prog_Id in the dimension and

Try

If(rating>10,Projection,'')

So how does this equation know and differentiate that the prog_id is the same?

In this case you are not grouping on the Prog_id so it checks the condition for each row. Hence it will check only for the rating not for the prog_id.
