Generate View Columns
To auto-populate the columns of a view, in the view configuration page, Data tab, scroll-down to the Entity View Columns section, click the Generate View Columns button and in the confirmation pop-up, click Yes..
The view has no fetch data
If the view has no fetch data, the view columns will be populated for all attributes specified in the text field if the field name does not already exist in view column. The column name will be set with the attributes label in the current language.
If you want to replace the display name of an attribute with its localized value, in the Label column of the entity view write the following syntax: {entityName.attributeName | metadata}.
Clicking the Generate View Columns button will add the missing columns.
The view has fetch data
If the view has fetch data, the view columns will be populated for all returned fields specified in the fetch (with alias to) field name that does not already exist as view column. The column name will be set with the attributes label in the current language.
When exporting the view using deployment packages, the label is localized so the label pattern: {entityName.attributeName | metadata} will be replaced with the displayName of the attribute.
