00210: <Value> uses the same layer ID as another layer/table: <value> assigned

You are sharing a feature, tile, or map image layer that contains layers or tables with the same layer or table ID. The first value parameter refers to a layer or table. The second value parameter refers to the duplicated ID value.


  • Replace duplicate IDs with unique IDs.

    Hover over the analyzer message. Click the Options button Options that appears and click Change General Layer Properties (for a layer) or Change General Standalone Table Properties (for a table). In the properties dialog box, on the General tab, change the Layer ID to a number that is unique in the map or scene.


    The analyzer creates separate errors for each layer or table with a common ID. If there are two duplicate values, you only need to change one.

  • Choose not to preserve the assigned IDs for your layers or tables.

    In the Contents pane, right-click the map name and click Properties Properties. On the Map Properties dialog box, on the General tab, uncheck Allow assignment of unique numeric IDs for sharing web layers.
