    or select
    Data Object profile
    from anywhere in the Analyst tool.
    New Profile
    wizard appears. The
    Column profiling
    option is selected by default.

  6. In the
    pane, select the project or folder where you want to create the profile.
    The Analyst tool displays the project that you selected and shared projects that contain folders where you can create the profile. The profiles in the folder appear in the right pane.
  7. Click
  8. In the
    pane, select the columns that you want to run a profile on. The columns include any rules that you applied to the profile. The Analyst tool lists column properties, such as the name, data type, precision, and scale for each column.
    Optionally, select
    to select all columns.
  9. In the

    Save & Run
    to create the profile and then run the profile.
