Hi guys,
I am trying to calculate the number of days being spent in each stage of manufacturing. The difference in two subsequent dates shows the result as the number of days spent in each stage of manufacturing process.
In the data set "Product_ID" PP540 has 5 stages so far and "Time_Spent_In_Each_Stage"shows number of days spent in each stage and the last manufacturing stage is Dryer which should be counting the number of days from the beginning of that stage to the whatever is the current date is.
Thanks for the help in advance!
Regards!
