Engineering Change Management (LO-ECH)
The data that contains all information required for managing a change.

The master record contains descriptive data, such as the reason for the change, and data with control functions, such as valid-from date and indicators for object types. In addition to this data, which can be updated directly, there is data that the system updates automatically, such as administrative data.

If you make a change with reference to a change number, or create an object with a change number, the following functions are at your disposal:

1. The system determines the effectivity parameters
The conditions that the change is effective under can be defined in the change master record as follows:
1.1. Changes with a date effectivity (valid from date)
1.2. Changes with parameter effectivity (for example: serial no. effectivity)
2. Log of the changes made
3. Documentation for the changes
4. Revision level to indicate the change status of a material or document
5. Changes released for the different areas in the company.
