Hi,
as this thread was created in the Greenbone Management Protocol (GMP) category it seems you have already found the starting point on how to extract the data from your scans.
See the description of this category below for various resources on this protocol and its API. To achieve what you’re looking for you probably need to write an own GMP script to extract the data you would like to see via GMP and then let the script import the data into Microsoft BI.
