Historian - Get Lot Name question

Historian - Get Lot Name question

Hi! I need help understanding the diference between this two options in the historian section:
  1. Get lot name from the variable at start
  2. Get lot name from the variable at end
I kwnow that is related to when do the variable is written, but when I try to check the lot name using the "Display lot dialog" even if the historian is not end yet, i see the lot name. (Image)

Also I'm not able to find any documentation related to this two options.

How can I checkif it is really seting the name at start/end?


-Thanks!
