With the reorganization function, you can delete planned independent requirements for which there are no sales orders in the database. You can delete the planned independent requirements history.

A key date is required to carry out reorganization which is calculated as follows: the system checks whether a reorganizing interval is maintained in Customizing for the plant that you want to reorganize. If an interval is maintained for this plant, the system uses this information to calculate the key date. If no interval is maintained for this plant, the system checks whether intervals are maintained for any other plants, and selects the largest interval to calculate the key date. You can change the key date proposed in the initial screen for reorganization.

You can change the proposed key date when deleting the history. You can set a shorter interval for deleting histories than for deleting the requirements records.
