Form Field Validation
This article describes data validation within SAP Fiori apps. This includes information about the validation points and the choreography associated with messaging.
For more information on the messaging concept for SAP Fiori apps, see the article on message handling.
On “Enter”
- The entire form is validated.
- If the user selects a value by pressing Enter, the value is selected without triggering validation (for example, when adopting a suggestion or entering a value in a combo box). The user must then press Enter a second time to trigger the full form validation process.
- Any errors or warnings are displayed in a message popover.
Validation
- Highlight the specific field and include a useful message (with an action word) in the value state. The message should have the following format: Short message description. For example: “Enter first name”.
- Display a button on the left side of the footer toolbar.
- The button displays the sap.m.MessagePopover. Find out more about this popover.
- If the issues have been resolved so that the user is able to proceed with his or her action, there is no need to display those messages anymore.
Depending on the floorplan, certain validation guidelines need to be applied.
Global Edit Flow
This floorplan is significant in that the actions are only displayed in the footer toolbar on the main page of the object. The subpages do not provide action buttons. Therefore, the message popover includes all messages for the whole object (the main object page and all subpages).
The messages can be triggered by the following:
- Focus out: Current field, or current field and dependent fields
- Action button: Complete object validation including subpages
Partial Editing
When the user clicks Save, the whole form remains in a busy state until the action has been completed:
- If there are no messages: switch to display mode.
- If there are messages that relate to a field: highlight the respective field with its value state and do not use the message popover.
- If there are messages that do not relate to a field, show a dialog with the message(s).
