Special Question: Amount of transferred data in AO

Hello Experts,

I have a special question in relation to BusinesObjects Analysis (in our case 2.2.1).

The question refers to the amount of transferred date ...

One example:

We use a query to get master data - for example of our customers.

The result of this query is a list of 115.000 rows and 8 column.

So far so good ...

If we monitor the network performance during the query is running, we are able to see that more than 150MB of data are downloaded.

And now our question is WHY? What ist the reason for this amount of data? Is that normal?

If I save the list, the file will have a size of 7MB.

Thank you for your ideas and your answers.

Best

Steffen
