How to visualize if a value is greater or smaller than another?

Hi Community,

I'm totally new to WEBI so bare with me please .... this questions might be very easy to solve.

I try to create a WEBI report which is based on a data-source which comes from another vendor.

The report includes three variables:

1. Device-Name (Type: String, Qualification: Dimension), Example "Router1"
2. *Device-Availability% (Type: Number, Aggregation: Sum, Qualification: Measure), Example "99,52 %"
3. Device-Availability-Target-String (Type: String, Qualification: Dimension), Example "97,50"

I want to setup a new column which will be filled with a green background color, if the *Device-Availability% >= Device-Availability-Target-String

and else with a red color.

First thought was to simply use an Alerter combining both variables but that doesn't work. So next thought... okay comparing a String with a Number

will not work. So I created a new variable (Measure) Device-Availability-Target-Number (=ToNumber([Device-Availability-Target-String]) and

tried those two variables in an Alerter. But again, no success.

Also tried using an If-Function but same result. It looks like WEBI compares the two variables in a way that I don't get.

Any ideas, any hints will be appreciated... I'm desperate

Thanks a lot,

Lemmy

Here is an Example of the table I'm using.
