Page Custom Fields Definitions
Custom Fields must be defined before they can be used. This page can be access directly when you choose the 
icon, enter Custom Fields Definitions, and then choose the related link.
Here you can setup the custom fields you want to use and where you want to use them. The following fields can be configured:
| Table | The list of tables that we currently support is shown here. Please select one of the tables to then define the different fields. |
| Type | The type of the custom field you want to define. |
| Field No. | You can select one of the field numbers from the list. The list shows the maximum number of fields for each type that can be defined for each table. |

| Min. Value | Minimum value that can be assigned for a field of type Decimal or Integer. |
| Max. Value | Maximum value that can be assigned for a field of type Decimal or Integer. |
| Edtiable | Defines whether the field is editable or not. If it is not editable, the value can be seen on this table, but not changed. |
| Set Dimensions | If this field is checked and dimension values are defined on the custom values for a Code or Text field, these dimension values will be applied to the table the field is added to when the value is selected. |

Actions
Values action
For Code fields, you can define a list of valid options in a separate table. These then will be the only options that you can enter in the fields on the pages. Every other entry will cause an error.
Please see more details on the Custom Values Page.
Copy To action
When you define fields, you can also define that those fields are copied to other pages. When you select the Copy To action, the page opens filtered on the Table of the current record and will allow you to define the tables the fields should be copied to for the entire table. The page will only show allowed actions, for instance:
| Copy From | Copy To |
|---|---|
| Item | Sales Line |
Please see more details on the Custom Fields Copy To Page.
Custom Lookup action
When you define fields, you can also define that those fields can only have a value from a different table (lookup table). While you can define values for those lookups through the Values action, you can also select existing tables within Business Central by defining Custom Lookups.
Please see more details on the Custom Fields Lookup Page.
Translations action
If you have users in different languages, you can setup translations for the field names. The current language is always automatically added as a translation. Based on the language defined in your settings in Business Central, the proper translation will be used. If the language isn't defined in the translation, the default language will be used.
Please see more details on the Custom Fields Translations Page.
Visibility action
If you setup fields, they are always shown by default on specific pages already. However, if you want to add the fields to more pages or remove fields from some pages, you can configure different pages. However, only pages that are shown in the visibility list can be activated.
