Document detailing changes to master records, tables, documents, and so on.

Normally, all changes to a material master record are stored in change documents automatically. Changes made in a single step are stored in the same change document, while changes made at different times are stored in different change documents. All the change documents that exist for a material make up its change history.

Change documents contain the following information:

• When the change was made

• Who made the change

• What value the field contained before and after the change
