Answer 1

Hai Go through the following Document
SELECTION-SCREEN COMMENT fmt name.
Additions
1. ... FOR TABLE dbtab
2. ... FOR FIELD f
3. ... MODIF ID mod
4. ... ID id
Effect
Generates a comment on the selection screen. For the name name , there are two options:
name takes the form TEXT-xxx where xxx is a three-character name for a text symbol. In this case, the contents of the text symbol are displayed at runtime, i.e. the text cannot be changed dynamically. name is another eight-character name. Here, you create a field with the name name in the length specified in the format fmt< /> and it is then generated as an output field on the selection screen. The contents of these comments must therefore be set at runtime (e.g. at INITIALIZATION or - in the case of comments in the database include program DBldbSEL - in the routine INIT of the database program SAPDBldb . They can also be changed when the selection screen is being processed.
Note
The field name is generated automatically and so cannot be defined with DATA .
With comments, you must always specify a format fmt (see variant ULINE ).
Note
You must program a new line yourself via the format fmt .
Addition 1
... FOR TABLE dbtab
Note
See variation 3 (SELECTION-SCREEN SKIP).
Addition 2
... FOR FIELD f
Effect
Since the comment is assigned to a parameteror a select-option , the help display shows the documentation of the reference field if this parameter or selection option.
In addition, the comment is suppressed if the reference object was set to 'invisible' via a selection variant.
Note
In database access routines, the comment is generated whenever the reference field is output. Therefore, you should not use the addition FOR TABLE with this variant.
Example
SELECTION-SCREEN BEGIN OF LINE.
  SELECTION-SCREEN COMMENT 10(20) TEXT-001
                   FOR FIELD PARM.
  SELECTION-SCREEN POSITION POS_LOW.
  PARAMETERS PARM LIKE SAPLANE-PLANETYPE.
SELECTION-SCREEN END OF LINE.
This code displays a 20-byte long comment followed by the parameter at the normal position ( POS_LOW ) on the same line. If the user presses F1 for both objects, the documentation of SAPLANE-PLANETYPE is displayed.
Addition 3
... MODIF ID mod
Addition 4
... ID id
