00033: Standalone table's data source is not supported

You are sharing a web layer that contains a table that is sourced by an unsupported data type.


Do one of the following:

  • Replace the unsupported data source with a supported geodatabase table. The following table lists unsupported data sources and suggested alternatives:

    Unsupported data sourcesSuggested alternatives


    Import CAD content into a geodatabase.

    Excel file

    Generate features for each Excel spreadsheet and load the resulting feature classes into a geodatabase.

    Web layers

    Load the original data source into a geodatabase.

    In-memory feature class

    Save in-memory data as a feature class in a geodatabase.


    Generate features and load the resulting feature classes into a geodatabase.

    Text file

    Convert the data to tables in a geodatabase.

    Geopackage table

    Convert the data to tables in a geodatabase.

    Table in a cloud data warehouse

    Import the data into a geodatabase.

  • Alternatively, if you do not need the stand-alone table that has an unsupported data source, you can remove the table from your map.

More information

Generally speaking, the best performance will be achieved by using datasets that are native to ArcGIS, that is, geodatabases and key raster and image datasets. In many cases, your unsupported dataset can be loaded into a geodatabase that can then be used in a web layer.

For best performance with geodatabases, use either enterprise geodatabases or file geodatabases. In some cases, with many simultaneous users, enterprise geodatabases are faster. Since enterprise geodatabases are DBMS based, they will scale better than file geodatabases in situations where you have a large number of users (hundreds of users or more).
