As a general rule, you cannot import an application created in a newer release of APEX into an earlier version. This is because the newer release may have features or attributes that are not supported or recognized by the older version. For example, you cannot import an application created in APEX 21.2 into APEX 19.2. However, you can import an application created in an older release into a newer one, as long as the application is compatible with the newer release. For example, you can import an application created in APEX 18.2 into APEX 21.2, but you may need to upgrade or modify some components to use the latest features.

An authentication scheme is a rule that determines if a user is authorized to access a specific component or feature of an application, such as a page, region, button, item, etc. An authentication scheme type defines how users are authenticated when they access an application. The authentication scheme type that supports authentication with social networks and enterprise identity providers that support OpenID Connect or OAuth2 standards is Social Sign-In. Social Sign-In supports authentication with Google, Facebook, and other social networks that support these standards. The other authentication scheme types do not support authentication with social networks or enterprise identity providers. They are:

• HTTP Header Variable: Authenticate users externally by storing the username in a HTTP Header variable set by the web server.
• SAML Sign-In: Delegates authentication to the Security Assertion Markup Language (SAML) Sign In authentication scheme.
• Open Door Credentials: Enable anyone to access your application using a built-in login page that captures a user name. Verified References: [Understanding Preconfigured Authentication Schemes - Oracle Help Center], [Social Sign-In - Oracle Help Center]

• Data Source: This field specifies the SQL query that returns the data for the chart. The query must include at least one column for the label and one column for the value of each data point. You can also include additional columns for grouping, color, or tooltip information.
• Value Column: This field specifies the column from the data source query that contains the numeric values for the chart. The values are used to plot the data points on the chart and determine the size of each data point or segment.

• Label Column: This field specifies the column from the data source query that contains the labels for the chart. The labels are used to display the name of each data point or segment on the chart or in the legend.
