The first <value> parameter refers to a layer or stand-alone table. The second <value> parameter refers to the duplicated ID value.
Do one of the following:
Replace duplicate IDs with unique IDs.
Hover over the analyzer message. Click the Options button that appears and click Change General Layer Properties (for a layer) or Change General Standalone Table Properties (for a stand-alone 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 stand-alone table with a common ID. If there are two duplicate values, you only need to change one.
Disable the option to assign static IDs to your layers or stand-alone tables.
In the Contents pane, right-click the map name and click Properties . On the Map Properties dialog box, on the General tab, uncheck Allow assignment of unique numeric IDs for sharing web layers.
