# Source restrictions in import scenarios

You can use source restrictions to filter the data that you want to extract from the source
for processing by the import scenario.
For example: Some customer number values in the source have
**CUST** prefixes.
You can specify a source restriction that selects only the records from
the source that have the **CUST** prefix in the customer number field.

To configure restrictions on the data that will be extracted from the source during the import, you specify conditions for the fields of the source file on the **Source restrictions** tab of the [Manage import scenarios (SM206025)](https://docs.vismasoftware.no/visma-net-erp/help/integration/integration-windows/manage-import-scenarios-sm206025/index.md) window. If you specify source restrictions, when the system prepares records for import, it selects only the records that conform to the specified condition or conditions from the source and imports only these records.

For example, suppose that you want to import only the customer records that have the
**CUST** prefix in the customer number.
In this case, you can add the condition to the source
restrictions that the external customer number field should start with the **CUST** prefix.
The
system will import only the records for which the customer number has the specified prefix.
