# Copying extra field information to another module

In Robaws you can use [extra fields](https://support.robaws.com/en/article/working-with-extra-fields-1vwszk1/) to record information that cannot be recorded in the standard fields.
You can create the **extra fields** in several different modules.

Some modules are connected to each other, and for these the values of the extra fields can be copied across between the modules on a one-off basis.
This is the case for the following modules:

* Customer > Quotation, Change order
* Quotation > Project, Order, Subscription, Invoice
* Order > Planning item
* Progress claim > Invoice
* Project > Order, Delivery note, Progress claim, Invoice, Planning item
* Change order > Order, Invoice
* Supply order > Call-off order

## Conditions

Before the value of the extra field is copied across as described above, a few conditions must be met:

* You must create the fields in two places in the [settings](https://support.robaws.com/en/article/general-settings-1han2yn/). Make sure you use exactly the same spelling (case and space sensitive) and the same extra field type.
* This only works if you create a file in another module from the (starting) module.

*Example: in Quotation and in Project I have an extra field 'Requested installation date'.  If I create a project from the quotation (via the action button), the requested installation date from the quotation file is filled in on the project file.*

||| Please note: the content is **not synchronised**. It is copied across once, and can then be edited independently in both modules.
