Tracking changes to master formulas

When you enable Change History in the Item Symbol, you can track these changes to master formulas.

Scenario Change History tab of the Item form
The first time a manufacturing item is designated as a master formula on a formula What happens when you specify a manufacturing item as the master formula on a formula? The formula and version are displayed in the Change History page for that manufacturing item.
If the master formula is reassigned to another formula Only the ‘before’ and ‘after’ versions of the master formula are displayed in the Change History page for that manufacturing item.

For example, suppose the manufacturing item is designated as the master formula for FS-001\0001. Later on, it is designated as the master formula for FS-002\0002.

The Change History page for the manufacturing item shows the old master formula value of FS-001\0001 and the new master formula value of FS-002\0002.
