The LEVEL_ID field from the ArcGIS Enterprise portal or ArcGIS Online does not display in ArcGIS Field Maps Designer

Description

When configuring a floor-aware web map in Field Maps Designer, the LEVEL_ID field does not appear in the Fields list. However, when viewing the same web map in the ArcGIS Enterprise portal or ArcGIS Online, the LEVEL_ID field is visible in the layer attribute table. This prevents configuration of forms or field visibility in Field Maps Designer.

The image below shows the LEVEL_ID field not displayed in Field Maps Designer.

Cause

This issue occurs when the layer is configured as floor-aware in the ArcGIS Enterprise portal or ArcGIS Online. The LEVEL_ID is a system-reserved field used by the floor-awareness framework to link operational layers to floor levels and enable floor filtering. Field Maps Designer hides it to prevent configuration changes that could disrupt the floor-aware structure. Refer to ArcGIS Field Maps: Create a map for more information.

Solution or Workaround

To make the layer editable or configurable in Field Maps Designer, remove the floor-aware layer for the web map in the ArcGIS Enterprise portal or ArcGIS Online.

Note:
This workflow makes the web map unavailable for use in ArcGIS Indoors apps.

1. Log in to the ArcGIS Enterprise portal or ArcGIS Online and click Content > My Content.
2. Open the web map. Refer to Portal for ArcGIS: View maps (Map Viewer) or ArcGIS Online: View maps (Map Viewer) for instructions.
3. In the Contents (dark) toolbar, click Map properties.
4. In the Map properties pane, under Additional layers, click X next to each floor-aware layer to remove it.
5. Save the map. Refer to Portal for ArcGIS: Save maps (Map Viewer) or ArcGIS Online: Save maps (Map Viewer) for instructions and more information.
