A few weeks ago, I did a blog post introducing the “EDAC” functions in Legato with a very brief example of how to create an NPORT filing and fill in a few fields. Well, I thought we would take that a few steps further, and show how you can use that to create an import function for a complex table like the Part C section of NPORT. This table is fairly involved because it has three possible layers of sublists (lists contained in other lists), and we’ll need to keep track of this. Therefore, this blog is going to discuss a lot of “level 1”, “level 2”, and “level 3” tables, all of which occur within a single data table. To help visualize what exactly is meant by these different levels, take a look at this screenshot from GoFiler:
