# Creating Direct Maps

Direct map is used when data from an object should flow to another object without any changes to the data. The data is transferred ‘as is’ from a designated field in the upstream object to a designated field in the downstream object.

{% hint style="info" %}
**Note:** The data may still get converted to fit the destination field’s data type.
{% endhint %}

Direct maps are displayed as solid lines on the dataflow.

An example of what a *Direct Map* might look like is shown below:

To create a direct map between the fields of two objects, drag the field’s input port of the downstream object and drop it on the field’s output port of the upstream object.

## Direct Map Types

There are four direct map types:

1. *Value Map:* This is the default map type. It is always created when a new map is created between two fields. A Value map transfers the field’s value between the two mapped fields.
2. *Field Name:* This map type will write the source’s field’s name to the destination field. Note that the destination field should have a suitable data type, such as String.
3. *Field Header*: This map type will write the source’s field’s header to the destination field. Note that the destination field should have a suitable data type, such as String.
4. *Field Data Type:* This map type will write the source’s field’s data type to the destination field. Note that the destination field should have a suitable data type, such as String.

To change a map type, right-click on the map line and select *Change Map Type* from the dropdown.

## **Usage**

The objects in this dataflow example are connected via direct field maps. Direct maps make it possible to connect the source field to the mapped destination field.
