Define Data Field Type

Information

In module customizing you can define for each data field how a data field is to behave in a user module or as what kind of field type it should act as, e.g. input field, checkbox, traffic light field, etc.
Some field types are only defined by a single customizing parameter, others, however, are defined by a combination of multiple parameters.
Below, you will find a list of the field types found in the application with specification of the necessary settings in module customizing so that a data field appears as the respective type on the interface.
Information on the use application of different field types, please refer to the Introduction and Program Operation help area.

Field Type	Only possible with DI type	Required parameter settings	Remarks
ID data field	Primary key data item (data item with Column type = UUID)
Input data field		DF behavior = i
Output data field		DF behavior = o
Link Data Field		DF behavior = e2/e4/e5 Action ID = ID of a module, macro, menu item or a method name from the module subclass or a variable for the respective object	See also: Customize Link, Button, Context Menu, etc.
Listbox data field		DF behavior = le/li LBMOD = ID of a listbox module Input only via list box = (optional)	See also: Customize Listbox
Date listbox data field	Data item with Column type = date	DF behavior = cc Data field configuration = paste one of the cc templates or write a definition	See also: Customize Date Listboxes with Calendar Function
Checkbox data field	Data item with Column type = Yes/No	DF behavior = i2/o2
Mandatory data fields		DF behavior = i or li Mandatory =	The Mandatory function can be applied to all fields that do not accept an empty value or zero, since space or zero do not count as entry. Using it for checkbox fields is not reasonable since here a check only takes place for activated checkboxes. Key data fields (Idents) do not have to be set to Mandatory since they are automatically mandatory entries so that, according to the data base rules, the record becomes valid. The mandatory function has no effect on date data fields. It is possible to save even if such a data field is blank. However, it can be queried using another DI.
Traffic light data field		DF behavior = o Traffic light DI = ID of a traffic light data item	See also: Customize Traffic Light DI
Continuous text data fields	Data item with Column type = CLOB	DF behavior = i/o, mi/mo Multiline = (optional)	In DF behavior = mi, an additional editor for formatting the text is displayed and in DF behavior = m0, the formatted text is displayed in the field. The Multiline parameter determines whether line breaks are possible in the continuous text data fields.
Hyperlink data field	Data item with Column type = HL: File in the DB or HL: Local file or HL: Linked file	DF behavior = h/ho	If the Output parameter is activated on the data area that contains the hyperlink or if the make_output() Python function is used, the hyperlink behaves as if it had ho DF behavior.
