Keeping only strongest values

[Aiadeva]

hi everyone !

I'm using Visual Analytics 8.2 , and I have a tricky question...

So I have this data sample :

IDAdherent	TypeContrat	IDPolice	IDTypeContrat
1	BASE	1	1
1	OPTION	2	2
2	BASE	3	1
3	BASE	4	1
3	SURCO	5	3
4	BASE	6	1
4	SURCO	7	3
5	BASE	8	1
1	BASE	9	1
1	BASE	10	1
5	BASE	11	1

IDAdherent is the ID of some people under one or more contracts (codified by IDPolice) with the value TypeContrat wich are 'BASE','OPTION' or 'SURCO'. The SURCO contract is 'stronger' than the OPTION contract which is stronger than BASE.

What I want to do in Visual Analytics is creating a list of those IDAdherent and their contract with the strongest value. 

With this sample, I would like something like this in visual analytics :

1	OPTION	2
2	BASE	3
3	SURCO	5
4	SURCO	7
5	BASE	8

Is it possible? 

PS: I know I can do this in SAS, but for some -complicated- reasons we can't do that . We need this to be done in Visual Analytics.

Thank you for your help !

Sorry for double post but... Nobody knows how to do that 😞 ?

I can give more informations if that's what you need !

So what is stopping you adding a flag to the data identifying the strongest rows before you load into VA memory? Then all you need is a simple filter to get the right rows.
