# Edit mapped value name

# Edit input and output mapped value name in Zero Copy Connector for ERP {#ariaid-title1}

Release version: Brazil  
Updated March 12, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 2 minutes to read  
Manually edit mapped value field names for input and output when managing models in Zero Copy Connector for ERP (Enterprise Resource Planning).

## Before you begin

Role required: sn_erp_integration.erp_admin

## About this task

In ERP model manager, the mapped value name in inputs and outputs is system-generated automatically. Edit the value manually as needed. Specify a unique value. You can revert to the system-generated name at any time.

Let's step through an example. In Zero Copy Connector for ERP, create a model. For more information, see [Create a model](https://www.servicenow.com/docs/3qabiHbBp6AV63fGAAhtxA "Add a model in Zero Copy Connector for ERP (Enterprise Resource Planning) to create a dataset containing tables from the ERP system to read and send updates to the ERP system.").

## Procedure

1. On the new model, select Manage Model and add a read operation.  
   For more information, see [Add an operation to a model in Zero Copy Connector for ERP](https://www.servicenow.com/docs/aImlQVW8gdvPX~CTNzODkg "Add an operation to an ERP model in Zero Copy Connector for ERP to define how the model retrieves data, writes data, or creates a new instance of the business object.").
2. On the read operation, add a read table entity, for example, on the T005 Countries table.  

   For more information, see [Adding an entity to a Zero Copy Connector for ERP model](https://www.servicenow.com/docs/WCTGTfbJwQTpW78bEv2N5g "Add an entity to a model operation to specify the ERP data that Zero Copy Connector for ERP reads, creates, or updates when the model runs.").
3. After data is retrieved, select Specify inputs.
4. Select Select mandatory inputs.
5. Select Country/Region Key and select OK.  

   The system-generated mapped value is countries_country_region_key. The operation parameter value is set to the same name.

6. Change the mapped value to, for example, country_region_key and select Save.  
   The updated mapped value is displayed and the operation parameter value changes to match automatically.

7. If a new input is added, the mapped value is system-generated but is editable.  
   For example, add the Nationality field and edit the name from countries_nationality to country_nationality so it's more consistent with the
   country_region_key name.

* If a new child (nested) input is added, the system-generated mapped value doesn't contain the parent name. You can edit the child name for inputs and outputs. For input, the edited name is used in the operational parameter. In this example, the UDAT and BASXML_SUPPORTED fields were added and their system-generated names can be edited to contain or more closely match the parent name.

* If a join is used, the changed name should be available on the join fields as well. For more information about joins, see [Add joins between ERP tables](https://www.servicenow.com/docs/0jdZIyuZIvMGk7vnQIv2~A "Link multiple ERP (Enterprise Resource Planning) tables to build an ERP model in Zero Copy Connector for ERP using table joins.").
* If the same field exists in both input and output, but they have different mapped values, the name of the output field is given precedence and used.
* If you want to revert to the system-generated name at any time, remove the field and then add it again. Another option is to change the mapping type and then change it back.
