Input mode allows data manipulation such as inserting new records, updating existing data, or deleting existing records from the database. In Input mode, the data you enter into the screen fields is not stored in the database unless you save the changes using the Save button on the toolbar, or by clicking File > Save to explicitly save the temporary data to the database.
While you are working on data in a screen, your input is checked for syntax and validity in terms of required fields, value ranges, and data types. The data content is validated again before it is saved to the database. This second verification includes checks for uniqueness of the new records with regard to the key fields and for references to records with nonexistent data, such as standardization data.
Screens that require immediate input or contain very little information are in the Input mode by default. When these screens are opened, the software has already completed the database query.
