2242885 - Data Changes in Supplier Are Not Being Logged

You noticed that some specific changes you do in Suppliers are not registered on Changes tab

1. Go to Supplier Base work center
2. Select Suppliers view
3. Edit any Supplier
4. Do some modification in supplier data (e.g: Add new company in Financial Data->Payment Data)
5. Save the changes
6. The changes were not registered in Changes tab

There is a technical reason behind this. 

For the records on change histories, not all business partner data (or supplier data) are recorded for change due to performance and data payload reasons.

The mentioned communication data for business document setting is not part f the data which are recorded for change history.

The behavior of data recording in Changes tab is not the same for all set of supplier data. For this reason, some kind of data will be recorded in change tab but some will not.
For example,  Bank Detail belongs to a node of Supplier and in this case it will be recorded.
Payment data is a separate component which is only bound to supplier via association for which the creation operation is not set for change document, so it will not be recorded in Changes tab.
