Hi All,
What a new discussion forum we have 
I am trying to create a simple elementary SHelp and attach it to selection screen field.
So basically I am haveing 2 screen fields, like:
PARAMETERS:
p_name TYPE tsp03d-name,
p_papr TYPE znl_printer. "F4
ZNL_PRINTER data element is of predefined type CHAR30.
It has elementary SHelp ZNL_PRINTERS attached (parameter name is NAME).
Selection method: TSP03D
SHelp parameters:
- SHelp parameter: 'NAME' (IMP=X, EXP=X, LPos=Spos=1, Data element=RSPOLNAME)
- SHelp parameter: 'PAPROSNAME' (IMP=X, EXP=X, LPos=Spos=2, Data element=RSPOPRNAME)
So now, let's say I am entering some value into the field p_name, for example *BOB*.
Then I click the p_papr field and press F4.
What I would like to achieve is to fill the NAME parameter of SHelp with a value of p_name selection screen field (*BOB*)
Could you please suggest what should that be done? I know I could use F4IF_INT_TABLE_VALUE_REQUEST FModule to build a SHelp internal table on the fly, based on screen fields value. But I need to use this functionality also in other programs. So developing the logic for each of them would be redundant.
Is there a standard / data dictionary way to achieve the result I described?
Would appreciate your comments.
Regards,
bob.
Hi,
For this filed is key filed and also it has foreign key relation ship?.if it is then f4 help is possible other case external we have provide.

Hi Bob,
To get the default value in search help we need to set the parameter id for that perticular field (p_name), before calling the F4 help.
Note: At the search help level set the default value of "name" parameter to it's parameter id.
You can set the parameter id in ' AT SELECTION-SCREEN on VALUE-REQUEST FOR p_papr' event.
But to if use value request then implicit F4 will not work. To call the search help explicitly u can use FM 'F4IF_FIELD_VALUE_REQUEST'
and to read the screen value to set the parameter id use FM 'FM_FYC_DYNPRO_VALUE_READ'.
To know it more clearly I have created an example.
code:
REPORT Y65_SHELP.
PARAMETERS:
p_dept TYPE yh2165_emp-dept,
p_empno TYPE yh2165_emp-empno.
DATA: fval TYPE DYNFIELDVALUE.
AT SELECTION-SCREEN on VALUE-REQUEST FOR p_empno.
CALL FUNCTION 'FM_FYC_DYNPRO_VALUE_READ'
EXPORTING
i_repid = sy-repid
i_dynnr = sy-dynnr
i_fieldname = 'P_DEPT'
IMPORTING
E_FIELDVALUE = Fval
.
set PARAMETER ID 'ZDEPT' FIELD fval.
CALL FUNCTION 'F4IF_FIELD_VALUE_REQUEST'
EXPORTING
TABNAME = 'YH2165_EMP'
FIELDNAME = 'EMPNO'
SEARCHHELP = 'YH2165_S_EMP'
SHLPPARAM = 'EMPNO'
DYNPPROG = sy-repid
DYNPNR = sy-dynnr
DYNPROFIELD = 'P_EMPNO'
EXCEPTIONS
FIELD_NOT_FOUND = 1
NO_HELP_FOR_FIELD = 2
INCONSISTENT_HELP = 3
NO_VALUES_FOUND = 4
OTHERS = 5 .
IF SY-SUBRC <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
If you any query please let me know.

Thanks a lot Rajeev!
Key for success was to assign Default value to SH's parameter 'PAMSSERVER'.
Your example was very helpful.
I am observing one more strange thing, when setting cursor on the p_papr screen field and pressing F4, search help is displayed properly, with initial value taken from screen, which is great.
But I am losing focus, that means immediately when SH popup table is shown, cursor sets itself on the screen field p_papr, and I need to click mouse on the SH again in order to be able to continue filtering and choosing values.
I have also observed that this symptom starts when additional parameters are used for 'F4IF_FIELD_VALUE_REQUEST' function module, that is:
dynpprog = sy-repid
dynpnr = sy-dynnr
dynprofield = 'P_PAPR'
Once they are added I am loosing focus... 
PS. I really need to get used to the new forum, also find where to reward points...
I would suggest you to check out search-help exit.
