I believe this report grabs data from all ledger entries for a specific customer (highlighted in red). Customer Ledger Entries isn't the same table or page as Customer / Customer Card but they are still grabbing its data for the current customer right now. I would like to implement the same functionality but from data on a different table on a different page (on a report extension). Kinda hard to wrap my head around since this isn't just one field I am getting from a different location, but a whole table of data for a specific customer.
Any guidance is appreciated.
