"IT System category name" is nullDictionary Link" IS NOT NULL - this restricts the results to only those lines where an executable has been found (i.e. removing lines where only the system has been found).

Filter

"IT System category name" is nullDictionary Link" IS NOT NULL - this restricts the results to only those lines where an executable has been found (i.e. removing lines where only the system has been found).

...

Key fields are: Process ID, Task ID, Lane Name, Dictionary Link (which represents the executable), IT System Title (which has been found when linking the executable lines to the system lines in the previous view).
