## Objektverwaltung
|
|
|
|
<AccordionGroup>
|
|
<Accordion title="Can I delete a custom object?">
|
|
Yes, custom objects can be deleted. You can also deactivate them first, which hides the object and its data from the interface while preserving the data.
|
|
</Accordion>
|
|
|
|
<Accordion title="Kann ich Standardobjekte (Personen, Unternehmen usw.) löschen?">
|
|
No, standard objects cannot be deleted. You can only deactivate them, which hides them from the interface but preserves the data.
|
|
</Accordion>
|
|
|
|
<Accordion title="How many custom objects can I create?">
|
|
You can create as many custom objects and fields as you need — the price doesn't change.
|
|
</Accordion>
|
|
|
|
<Accordion title="Can I rename a standard object?">
|
|
You can rename the label of standard objects (People, Companies, Opportunities), but not their API names. The API names are fixed for consistency across all Twenty workspaces.
|
|
</Accordion>
|
|
|
|
<Accordion title="Can I change an object's icon?">
|
|
Yes, you can change the icon for both standard and custom objects in **Settings → Data Model**.
|
|
</Accordion>
|
|
|
|
<Accordion title="Kann ich die Objekte in der linken Navigationsleiste umordnen?">
|
|
Noch nicht. Die Reihenfolge der Objekte in der Navigation ist derzeit festgelegt, aber diese Funktion ist für eine zukünftige Veröffentlichung geplant.
|
|
</Accordion>
|
|
|
|
<Accordion title="Kann ich Objekte in der linken Navigationsleiste ausblenden?">
|
|
Alle aktiven Objekte erscheinen in der Navigation. Sie können Objekte, die Sie nicht benötigen, unter **Einstellungen → Datenmodell** deaktivieren.
|
|
</Accordion>
|
|
</AccordionGroup>
|
|
|
|
## Feldmöglichkeiten
|
|
|
|
<AccordionGroup>
|
|
<Accordion title="Can I change a field type after creation?">
|
|
No, field types cannot be changed after creation. If you need a different type, create a new field with the correct type, migrate your data, then deactivate the old field.
|
|
</Accordion>
|
|
|
|
<Accordion title="Warum brauche ich unterschiedliche Singular- und Pluralnamen?">
|
|
Unsere GraphQL-API verwendet beide Formen für verschiedene Operationen:
|
|
|
|
* `createPerson` (Singular) für Einzelaktionen
|
|
* `createPeople` (Plural) für Massenoperationen
|
|
|
|
Dies schafft Einschränkungen, wenn Singular- und Pluralformen gleich sind, verbessert jedoch die Entwicklererfahrung.
|
|
</Accordion>
|
|
|
|
<Accordion title="Warum sind einige Feldnamen geschützt?">
|
|
Bestimmte Feldnamen wie `Typ` oder `Applikation` sind für Systemnutzung reserviert. Wählen Sie stattdessen alternative Namen wie `Kategorie` oder `Klassifikation`.
|
|
</Accordion>
|
|
|
|
<Accordion title="What happens when I deactivate a field?">
|
|
* The field is hidden from the interface
|
|
* Existing data is preserved
|
|
* You can still access the field via API
|
|
* Existing relations remain but you can't create new ones
|
|
* You can reactivate the field later
|
|
</Accordion>
|
|
|
|
<Accordion title="Can I make a field required?">
|
|
Currently, you cannot make custom fields required. All fields accept empty values. You can use workflows to enforce required fields by sending alerts or blocking actions when fields are empty.
|
|
</Accordion>
|
|
|
|
<Accordion title="What's the difference between unique and required?">
|
|
* **Unique**: No two records can have the same value in this field
|
|
* **Required**: The field must have a value (not currently supported for custom fields)
|
|
</Accordion>
|
|
|
|
<Accordion title="Can I create formula fields?">
|
|
Formelfelder kommen im **1. Quartal 2026**. In der Zwischenzeit können Sie Workflows verwenden, um Feldwerte automatisch zu berechnen und zu aktualisieren.
|
|
</Accordion>
|
|
|
|
<Accordion title="Kann ich verschachtelte Felder in meinen Objekten haben?">
|
|
Verschachtelte Felder kommen im **1. Quartal 2026**. Aktuell können Sie Workflows verwenden, um Felderwerte von verwandten Objekten einzuholen. Zum Beispiel: Um die Branche eines Unternehmens in einem Personen-Datensatz anzuzeigen, erstellen Sie ein benutzerdefiniertes Feld für Personen und verwenden Sie einen Workflow, um den Wert zu synchronisieren.
|
|
</Accordion>
|
|
|
|
<Accordion title="Kann ich Felder in Objekten umsortieren?">
|
|
Feld-Umsortierung wird mit benutzerdefinierten Layouts im **4. Quartal 2025** verfügbar sein. Currently, fields appear in alphabetical order.
|
|
</Accordion>
|
|
</AccordionGroup>
|
|
|
|
## Beziehungen
|
|
|
|
<AccordionGroup>
|
|
<Accordion title="Can I have a relation pointing to the same object?">
|
|
Ja! Self-referencing relations are supported and recommended for use cases like account hierarchies. For example, create a relation from Companies to Companies to track parent/child accounts.
|
|
</Accordion>
|
|
|
|
<Accordion title="Kann ich Viele-zu-Viele-Beziehungen erstellen?">
|
|
Many-to-many relationships are coming in **H1 2026**. Currently, create an intermediate object with two one-to-many relationships as a workaround.
|
|
|
|
For example, to link People and Projects (many-to-many), create a "Project Assignments" object with:
|
|
|
|
* A relation to People (many assignments → one person)
|
|
* A relation to Projects (many assignments → one project)
|
|
</Accordion>
|
|
|
|
<Accordion title="What are relations to multiple object types (Morph relationships)?">
|
|
These allow one object to relate to multiple different object types through a single field. For example, Notes can be attached to People AND Companies AND Opportunities simultaneously.
|
|
|
|
Each Note links to one Person, one Company, and one Opportunity at the same time.
|
|
|
|

|
|
</Accordion>
|
|
|
|
<Accordion title="Can I have multiple relations between the same objects?">
|
|
Yes, you can create multiple relations between the same two objects. For example, a Company could have both a "Primary Contact" and "Billing Contact" relation to People.
|
|
</Accordion>
|
|
|
|
<Accordion title="What happens to relations when I delete a record?">
|
|
When you delete a record, the relation link is removed from the related records. The related records themselves are not deleted.
|
|
</Accordion>
|
|
|
|
<Accordion title="Can I create circular relations?">
|
|
While technically possible, circular relations (A → B → C → A) should be avoided as they can cause confusion and potential performance issues.
|
|

## Zugriff und Berechtigungen
|
|
|
|
<AccordionGroup>
|
|
<Accordion title="Wo kann ich mein Datenmodell sehen und bearbeiten?">
|
|
Go to **Settings → Data Model** to view and edit all your objects and fields.
|
|
</Accordion>
|
|
|
|
<Accordion title="Warum kann ich das Datenmodell unter Einstellungen nicht sehen?">
|
|
Wenden Sie sich an Ihren Arbeitsbereichs-Administrator. Der Zugriff auf das Datenmodell ist in der Regel nur für Administratoren eingeschränkt.

## Data Management
|
|
|
|
<AccordionGroup>
|
|
<Accordion title="Is there a limit to how many records I can have?">
|
|
There's no hard limit on record counts. However, very large datasets may impact performance in some views. Use filters and views to manage large datasets effectively.
|
|
</Accordion>
|
|
|
|
<Accordion title="Can I import data into custom objects?">
|
|
Yes, you can import CSV data into any object, including custom objects. The import process supports field mapping for custom fields. See [How to Prepare Your CSV Files](/l/de/user-guide/data-migration/how-tos/prepare-your-csv-files).
|
|
</Accordion>
|
|
|
|
<Accordion title="Can I export my data model configuration?">
|
|
Currently, there's no built-in export for data model configuration. Contact support if you need to migrate your data model between workspaces.
