Dictionary Attributes

For further screen element attributes, refer to General Attributes.

The Dictionary attributes comprise the following:

Attribute	Description and Usability Guidelines
Format	Data type. The data type determines what checks (valid date, numeric values) the system should perform on field input and how to convert the field for input/output. This field is always blank for keywords. For a list of the available data types, see Defining the Field Format.
From Dict.	Specifies the current ABAP Dictionary reference. The system sets this attribute if you created this field by copying it from the Dictionary. If you assign a name to a new element or change the name of an existing element so that the name contains a - (dash), the system checks whether the field exists in the Dictionary. If the name exists, the systems asks if you want to refer to the Dictionary field or not.
Modified	The system sets this attribute if it detects a difference between the Dictionary definition for the field and the way it is used in the screen. Set this attribute if want to use a keyword that diverges from its Dictionary definition.
Conv.Exit	If you want the system to use a non-standard conversion routine for the conversion of field input, specify a four-character code here. There are two supported conversion routines: CONVERSION_EXIT_ <name> _INPUT CONVERSION_EXIT_ <name> _OUTPUT See the SAPCNVE program documentation for more information.
Search help	Allows the user to specify a search help as input to the element. Enter a four-character search help file name or the name of a field that contains the file name. In the latter case, prefix your input with a : (colon). For more information on search helps, refer to the ABAP Dictionary documentation.
Reference Field	For tabstrip controls: Establishes the link between a tab title and a subscreen area. For currencies and quantities: Specifies a currency or unit key. This attribute is valid only for fields of type CURR (currency) or QUAN (quantity). If the screen element contains a currency and the field type is CURR, you must enter the currency key field belonging to the currency (CUKY). If the screen element contains a quantity and the field type is QUAN, you must enter here the unit key field belonging to the quantity (UNIT). If the screen element is from the Dictionary, the system takes over the reference field without allowing any changes.
Parameter ID	ID for a SET/GET parameter (up to 20 characters long). This attribute is used with either the SET parameter or GET parameter attribute.
SET parameter GET parameter	Set and display default in an element. If you choose Set Parameter, the system stores the value entered by the user in the relevant Parameter ID parameter. If you choose Get Parameter, the system displays the value in Parameter ID in the element instead of the initial value.
Foreign key check	Determines whether the system performs a foreign-key check for the field. The field's definition in the ABAP Dictionary defines the foreign-key check.
Upper/Lower case	Set this attribute if your program handles the user's input as a literal. If not, the input is converted to all upper-case. Usability note: Set this attribute wherever possible. Mixed case input is easier to read than uppercase.
