Dear Khun Yutthana,
I do final adjusted to group TU & FT again, sorry that I save without paste value then formula is cannot use. So, could you please revise on your original file to grouping base on attached sheet.
Group-A only start HI and then TU
Group-B only start TU->FT or FT->CT->TU
Group-C special process, combine all process but main objective is focus balance on FT job.
Best Regards,
Anusorn
