Engineering Change Management for Substances

Use

This function enables you to carry out data changes for a particular key date using a change number. Each change number is valid from a particular validity date so that the data have a validity period in accordance with the change number.

When you change existing data, R/3 Product Safety creates a change comment that contains the person responsible for the change, and the change date.

If you make changes without using a change number, the standard validity period used goes from 01.01.0001 to 31.12.9999. The system enters the current date as the key date.

When you use change numbers for the first time, the R/3 System divides the overall validity period into two adjoining validity periods. Whenever you use other change numbers that feature different validity dates, the system carries out further subdivisions of validity periods.
