I'm now having a problem when running the table by power query.
What my idea is i'll have concurrent update to sheet 1 while sheet 2 is stable. (i.e. cell used in sheet 1 is more than sheet 2)
however, when i update information to sheet 1, I refresh the data again, the power query can't update the same from sheet 2 and leave some column as 'null'.
P.S. since the attached file is just for my testing and my original one is not appropriate to share here. For more information, my original 'sheet 1' has around 10000 row while 'sheet 2' is just 150 row, and my task is to automatic pull the data from sheet 2 to fill in some column to sheet 1 when there's any update.
