To directly answer your question about creating a new Action button to view the records, my guess was correct, LINKTOFILTEREDVIEW is what you want to use for that.
However I highly suggest you forget about that, and instead get your tables referenced to each other properly. The [Item Name] column in the Log Table should be a Ref type column, pointing to the Items Table. When you do this, the editor will automatically create a Virtual Column, using the REF_ROWS expression, with a name of “Related Logs” (or similar). This column will appear as an “inline” Table in each Item’s Detail View, showing just the Log records related to that Item. I recommend that you review some of the existing inventory management sample apps here:
