You use field labels to assign text information to a data element. You can assign field labels as prefixed text to a screen field referring to the ABAP Dictionary.
You can copy structure components and table fields from the ABAP Dictionary to the input template when you define a screen in the Screen Painter(Get from Dict.function). You can also assign a field label to a field. The field label in this case is derived from the data element of the field.
The text of the field label can be translated centrally with the translation tools. The text is then displayed in the input template in the user's logon language.
Short, Medium and Long Field Labels
Short, medium and long field labels are keywords of different lengths for identifying screen fields. Since the space available for such texts depends on the input template, you can define the text information in three different lengths.
A maximum length must be assigned for each field label. It is the upper limit for the lengths of all translations of the given text.
The maximum length of the field label must be somewhat longer than the given text in the original language.
You use this text as a column header when you output the contents of fields as a list in the Data Browser. It can also be assigned to a field in the Screen Painter.
A maximum length must also be assigned for the header. It is the upper limit for the lengths of all translations of the header. Choose the maximum length of the header to be somewhat longer than the given text in the original language.
The system displays the header above the corresponding column when preparing list output. The length of the header must not exceed the length of the data element.
