WADACO- REPORT_PICK_PART_SO_PICK_LIST- Why can't the system find the last line of the pick list?

The Last Line on Pick List feedback item works only in a so called subsequent loop where you loop on your own process/configuration, it don’t work for a this type of intern loop, it will always display No in that scenario. If you have an internal loop you can just remove it since it will just confuse the user. For the current internal loop handling you are suppose to manually press exit loop when you think its finished, the LOV for unique_line_id will be empty when there is no more lines that would also indicate that you can exit the loop now.

This usually works better if you don’t use intern loop and instead use the subsequent loop variant since then this Last line on Pick List will work properly.
