Definitions for "net change"
The difference between the close of a security or commodity on one trading day...
An MRP or other planning system generation that only recalculates requirements for items that have changed since the last generation, due to the addition or changes in order quantities and dates, inventory levels, bill of material or routings, lead times or other parameters. A flag is usually set by programs that initiate changes for those items, which is used by MRP as the basis to regenerate them. It typically reduces generation time and is most useful for companies that have many part numbers, a small percentage of which are active in a given week.
The daily change from time frame to time frame. For example, the change from the close of yesterday to the close of today.
