Contact activity: track changes to your contacts

The screenshots in this article show the German interface. The English label is given first, with the German label in square brackets.

Who changed the billing address — and when? For contracts, the change log has been answering questions like these for a long time. With the Activity [Aktivität] tab, the same traceability is now available for your contacts as well.

Every contact keeps its own change history — from the original state at the time of creation through to the most recent amendment.

What's in it for you

• Full traceability. You can see at a glance when contact data has changed — including the values in detail.
• The initial state is preserved. The "Original contact data [Ursprüngliche Kontaktdaten]" entry documents the data the contact was created with.
• Fewer follow-up questions within the team. Instead of asking around who made a change, you look at the history.
• Consistent with the contract. You already know the logic from the change log of your contracts — now it runs right through to contact level too.

How it works

1. Open the contact

Go to "Contacts [Kontakte]" and open the contact you want.

2. Open the Activity tab

In the contact's right-hand sidebar you will find the "Activity [Aktivität]" tab next to "Contracts [Verträge]" and "Tasks [Aufgaben]".

3. Read the change history

Under "Change history [Änderungsverlauf]" you will see all entries with date and time — beginning with "Original contact data [Ursprüngliche Kontaktdaten]" at the time of creation.

4. Expand the details

"Show details [Details anzeigen]" expands the individual field values of an entry (for example name, address, telephone number) — "Hide details [Details ausblenden]" closes them again.

Common questions

Which changes are recorded?
Changes to the contact data — from the name and the address fields through to fields from your contact field builder [Kontaktfeldbaukasten]. The history starts with the original state at the time of creation.

Do I see the history for all contacts?
You see the Activity [Aktivität] tab on all contacts you have access to — the usual visibility rules for contacts apply here as well.

Can I restore an earlier state?
The history documents changes, but it is not a restore function. You can take earlier values from the details and reset them manually if required.

Where do I find the contact's contracts and tasks?
In the same right-hand sidebar — the "Contracts [Verträge]" and "Tasks [Aufgaben]" tabs show all of the contact's links.

Good to know

• Useful for contact maintenance too: before merging duplicates it is worth taking a look at the history of both contacts — that way no information is lost.
• Complements the contract change log: you will still find contract changes on the contract itself; the Activity [Aktivität] tab on the contact concerns the contact data.
