6. In Select type, select Read.
7. Select Save and continue.
8. Select the Read operation tile.
9. Select Select entity.

12. In Search, start typing any part of a table name and make a selection from the list.

    ![Preview table data page with a tile highlighted to show that the icon is now green.]()
14. Select the tile.
15. Explore the information available for the table.  
    Ten rows of randomly selected records are displayed. Use the Query option to search for a specific record.  
    Note:  
    If no records are found when querying, an error message is displayed. Select the View details link to open a new browser tab containing information about the error.

    The Selected fields section contains the columns that are displayed in the records list at left.

    All fields associated with the table are listed and are categorized based on data type, such as date or time. Edit the Selected fields section by selecting a pill to remove it from the list or
    expanding a category and selecting a pill to add it to the list.  
    Note:  
    It is recommended that no more than 7-8 fields be added to the Selected fields list so information is displayed clearly in the records list.

    To find a specific field, use the search. Keywords you enter are used to search the description, table type, and the table name.

16. Continue to search for tables or select table tiles in Recently viewed tables and explore the table contents.

## What to do next

After viewing tables, select Manage entities, then Select entity. In Select type, select Read and in Select entity specify the table for the read operation to use.
