Hi I have a datase that retrieves a list of Servers and metrics, for example:

agent oid id
server1 CPUUsage 14
server1 MemoryUsage 15
server2 CPUUsage 16

and then I have the information of the avg, max and min measure for each metric in another table, for example

id date avg max min
14 2011-10-19 15:00:00 5 10 2
15 2011-10-20 15:00:00 6 20 4
14 2011-10-20 15:00:00 25 50 15

and both tables are related by the id field.

I want to create one graphic por each metric, that means one graphic for server1 CPUUsage (id = 14), server1 MemoryUsage (id=15) and server2 CPUUsage (id = 16).

So on the secon dataset used for retriving the values I need in the where clause something like id = (select id from table where agent = 'server1' and oid ' 'CPUUsage')

but this two values should be replaced dinamically for each graphs with the values from the first dataset (which has all the values of the server-metric possible relations).

IS there a way to do this? I wasn´t able to find how to acomplish this, any help will be useful

Are you using BI Publisher? If so, forget about doing this inside of it. To accomplish this, the easiest way I know would be to create a web-service that will do the job, and load your that in the publisher from that WebService. You can also struggle with DataTemplate, but I don't think it can be done.

Hi Daniel, BI publisher is a BIRT module?

Why not use a joint dataset and join the two tables or use nested
tables. Look at this example for nested tables:
