I have a calculation that calculate how many glue is using per each product during production.
Below is one of my calculation:
Unit = "PARR" ; QTY * 2 * Glue_Usage::DJ_11 / 1000 ;
QTY * Glue_Usage::DJ_11 / 1000
However, now one of the product's glue usage is changed, if I update it on my filmmaker database, it will also affect my old record.
In this case, what should I do?
