Setting the cursor on a particular input field in module pool

Question

Hi,
I am working on an abap module program, the requirement is the cursor should be placed on a particular field at run time.
In detail:  Table contains zserialno primary key field, zemailid of char type.
Screen design: 1st text input field is zserialno
                         2nd field zemailid is splitted into 3 input text fields.
For 2nd field zemailid 1st input field allows user to enter his/her email name, 2nd input field is an drop down which contains domain names and 3rd field is an empty field which is to be triggered on user action.
example: zemailid- 1st input field  XYZ 2nd input field conatains @gm../@yah....and others. If user selects on others value in drop down of 2nd input field, the cursor should point the 3rd input field which allows the  user to enter his/her other domain.
I used
SET CURSOR FIELD <3rd inpu field namet>.
, but the cursor pointing the key field of the table zserialno even the input field of zserialno was provided with a value.
Any idea on this is appreciated.

Answer 1

Hi Sona,
F1:
Effect:
During PBO processing, this statement sets the cursor in the screen layout of the current screen. The cursor can be positioned by entering a screen element after FIELD or by entering a specific position using col and lin. Outside of PBO processing, the cursor is positioned in the next list displayed on the screen.
If the SET CURSOR statement is not specified, depending on the definition of the screen, the cursor is set according to the following hierarchy:
    On the cursor position determined statically in the screen properties,
    On the first input field of the screen,
    On the first screen element of the screen,
    On the command field in the systemtoolbar.
The latter also applies if the command field in the system toolbar is not displayed.
I'm convinced your code works as designed.
Let us know your PBO module and code.
