9. Custom Fields

Custom Fields allow users to extend the standard ATLAS ETRM data model by capturing additional, organization-specific information on Back Office entities such as Master Agreements, Assets, and Companies.

They are used when business requirements demand storing structured data that is not available in the default system fields (e.g. regulatory classifications, technical characteristics, internal identifiers). This enables organizations to adapt the system to their operational and reporting needs without requiring system customization.

Once configured, Custom Fields are available directly within the Custom Fields tab of the corresponding Back Office records, where users can view and maintain their values as part of the standard data entry workflow.

Custom Fields support different data types, can be defined as mandatory, restricted to specific entity types, or configured to maintain values over time (Time Sliced), depending on business requirements.

Supported Entities

Custom Fields can be defined for the following entities:

• Master Agreements

• Assets

• Companies

Configuration

Custom Fields are configured via Administration → Custom Fields, where the user selects the relevant entity category.

Each category includes two main tabs:

• Custom Fields

• Custom Fields Representation

Custom Fields tab

This tab displays all existing Custom Fields for the selected entity. New fields can be created using the "+" action.

When defining a Custom Field, the following properties are available:

• Name (required): The label displayed in the Back Office record.

• Type (required): The data type of the field (see available types below).

• Entity Type Dependencies (optional): Restricts the field’s visibility to specific types (e.g. only certain Asset types). If not defined, the field appears for all records of the entity.

• Description (optional): Internal description for documentation purposes.

• Required: If enabled, the field must be completed when creating or editing a record. Enabling this also requires setting a Default Value.

• Time Sliced: Allows the field to store different values across time periods.

• Add External Endpoint (for Option Types only): Enables dynamic population of selectable values from an external source.

Custom Fields Representation tab

This tab controls how Custom Fields are presented within the Back Office UI.

Users can define Groups, each with a name, optional description, and display order, and assign fields to them via drag-and-drop.

• Groups appear as separate sections in the Custom Fields tab of the record

• Fields not assigned to any group are displayed under General Custom Fields

This allows logical organization of fields, improving usability and data entry efficiency.

Custom Field Types

For all lookup-type fields (Master Agreement, Deal Cluster, Timeseries, Deal, Counterparty, Asset), the user starts typing a name and the system performs a live search against the corresponding records in the Back Office.
