# Manage input parameters

# Manage input parameters for a model operation {#ariaid-title1}

Release version: Brazil  
Updated October 22, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 4 minutes to read  
Specify how fields on the ERP (Enterprise Resource Planning) system map to input parameters and their values. Mapping defines the inputs for an operation that reads, creates, or updates the ERP system from Zero Copy Connector for ERP.

## Before you begin

Role required: sn_erp_integration.erp_admin

## About this task

If you're already in the process of managing a model and ready to specify inputs, you can skip to step 5.

## Procedure

1. Navigate to AllZero Copy Connector for ERPZero Copy Connector for ERP Home.
2. Open the ERP model page by selecting the models icon ![]() in the side panel.
3. Select the model with the operation that you want to add inputs to.
4. Select Manage model.
5. Open a model operation.  
   If you don't have a model operation, add one to the model. 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.").
6. Check that at least one entity is listed.  
   If you don't have an entity, add one to the operation. 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.").
7. Select Specify inputs.  
   The required parameters for the operation appear in both of the following places:
   * The Operation parameters section.
   * The Table/Functioncall section, where you define the parameters the operation uses. The Table section appears for read operations, and the Functioncall section appears for BAPI (Business Application Programming Interface) operations.Zero Copy Connector for ERP automatically suggests mappings between table fields in source systems and target models. For example, map the fields of source table purchase order - v2 with the fields of a relevant target table such as platform table purchase order. This reduces the amount of manual work to do, while still giving you control to edit
     the mappings as needed. For more information, see [Zero Copy Connector for ERP AI semantic field mapping](https://www.servicenow.com/docs/PnRwLRfKNur2E6ZC7Udh4w "Semantic field mapping uses AI to rank target fields in the platform data model by how closely their meaning matches a selected source field.").

     Mapped value names in inputs and outputs are generated automatically, but you can edit the names manually. For more information, see [Edit input and output mapped value name in Zero Copy Connector for ERP](https://www.servicenow.com/docs/9Vbw~I2_NPLzk53nNiJTVQ "Manually edit mapped value field names for input and output when managing models in Zero Copy Connector for ERP (Enterprise Resource Planning).").

8. Review the required and optional parameters that are already defined for the operation to understand what you must add.
9. Define a new input parameter to be sent when querying the ERP system.  
   For table read operations, a Tables section appears in the mapped table fields section for each defined table entity. Make sure that you're adding the parameter for the correct table.  
   Note:  
   It doesn't matter what order you define parameters in. Zero Copy Connector for ERP displays optional parameters in alphabetical order when you save.
   1. Select + New input previous the last-defined parameter in the table.  
      Note:  
      When you add an input field, the field is automatically added as a field in the output. The field is listed and is read only in the Prepopulated outputs section on the output page.
   2. Fill in the fields to define the parameter.  
      {#erpc-manage-model-inputs__table_jp5_t43_1bc__entry__2}

      | Field | Description |
      |-|-|
      | Field label | Name of the field from the ERP system that you're defining as a parameter. Zero Copy Connector for ERP automatically retrieves fields from the table defined in the operation entity. |
      | Field name | (Read-only) Name of the field in the ERP system. |
      | Data type | (Read-only) Automatically populated value that specifies the type of data the parameter contains. |
      | Mapping type | Definition of how the parameter is sent. * Input parameters have their Mapped value automatically populated. * Constant defines a parameter whose value never changes, for example, to use as filter criteria. You must specify the value in the parameter's Mapped value field. * Outer or Inner Join (table read operations only) indicates that you're creating a table join. For more information, 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."). {#erpc-manage-model-inputs__ul_nnc_rp3_1bc} |
      | Mapped value | Specific value of the parameter. * For Input parameters, accept the system-generated name or edit the name. For more information about editing mapped values, see [Edit input and output mapped value name in Zero Copy Connector for ERP](https://www.servicenow.com/docs/9Vbw~I2_NPLzk53nNiJTVQ "Manually edit mapped value field names for input and output when managing models in Zero Copy Connector for ERP (Enterprise Resource Planning)."). * For Constant parameters, enter a set value that's always sent for the parameter. * For Outer or Inner Join parameters, select the field to join the parameter with. For details on creating 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."). {#erpc-manage-model-inputs__ul_ald_y3p_1bc} |

   {#erpc-manage-model-inputs__substeps_wmm_ym3_1bc}  
   If you're adding a complex, nested parameter, such as an address that includes other parameters, Zero Copy Connector for ERP automatically identifies that it needs additional related parameters. Zero Copy Connector for ERP creates new, nested parameter rows that you must then populate with the related values. You can nest only parameters with Object or Array as the Data type.
10. **Optional:** Remove any optional parameters that you don't need when querying the ERP system by selecting the remove (X) icon.
11. Make any additional edits to existing parameters.  
    The following example shows an input with nested inputs for a BAPI.

12. Select Save.

## What to do next

Next, check the output parameters for the operation and update as needed. For more information, see [Choose output parameters for a model](https://www.servicenow.com/docs/O7jI9elC8QwfGvKGRNGetg "Specify output parameters for a model operation in Zero Copy Connector for ERP to define which ERP fields map to the ServiceNow AI Platform and how the returned data is stored.").
