How do I copy an object field to an booking field?

It is possible to work with custom fields at reservation and/or object level. In themselves, these fields can be used side by side. In some cases, it is desirable to include the object data in the reservation.

What do we need to set?

We set this at object level, so at the source and not at the target.

1. Go to Configuration -> Forms -> Object fields
2. At the source field, click on Advanced
3. Now enter a new key/value here by clicking on "Add parameter"
4. Now enter the key in this format: "target_booking_<<FIELD NAME>>".
5. Enter a value of "1". (Note: as long as a value is entered, it is fine. An empty value ensures that the field is not saved).
In the example in this article, this is called "target_booking_custom02". Where "custom02" stands for "Custom 02".

It should be exactly this value, this is the technical name of the field.

Note: one source field can possibly have multiple target fields.
