Hi,

Please check this it may help you out.

Use the function module 'DYNP_VALUES_READ' to get the value of the first search help. Then retrieve the values of the 2nd search help using the above value selected by a select query.

Use this function module "F4IF_INT_TABLE_VALUE_REQUEST"

to create the 2nd search help.

Write the above logic in at selection-screen on value request for the field of 2nd search help field.

Soumya

Use the below function modules for your requirement:

1) DYNP_VALUES_READ

2) F4IF_INT_TABLE_VALUE_REQUEST and

3) DYNP_VALUES_UPDATE

DATA: ok_code LIKE sy-ucomm.

DATA : matnr LIKE mseg-matnr.

TYPES : BEGIN OF ty_mat ,

mblnr LIKE mseg-mblnr,

END OF ty_mat.

DATA : dyfields LIKE dynpread OCCURS 1 WITH HEADER LINE ,

itab2 TYPE TABLE OF ty_mat WITH HEADER LINE,

wa_tab2 TYPE ty_mat.

DATA : value_tab LIKE wa_tab2 OCCURS 0 WITH HEADER LINE,

field_tab LIKE dfies OCCURS 0 WITH HEADER LINE,

return_tab LIKE ddshretval OCCURS 0 WITH HEADER LINE.

DATA : yr LIKE mseg-mjahr,

tp LIKE mseg-bwart.

declare this data in TOP module...

Here i am entering Material firts...

Then pressing enter and click on F4 help icon in secong field material doc (mblnr) , so only related doc will come.

select one from them and press enter....year and movement type will come automatically...

here my screen fields are ( I/O fields)

MATNR

ITAB2-MBLNR

now make one module in PAI...

PROCESS AFTER INPUT.

MODULE USER_COMMAND_1000.

PROCESS ON VALUE-REQUEST.

FIELD itab2-mblnr MODULE matdoc.

MODULE matdoc INPUT.

SELECT mblnr FROM mseg INTO CORRESPONDING FIELDS OF TABLE itab2 WHERE matnr = matnr.

SORT itab2 BY mblnr.
DELETE ADJACENT DUPLICATES FROM itab2.

CLEAR : value_tab,field_tab,return_tab.

REFRESH : value_tab,field_tab,return_tab.

field_tab-fieldname = 'MBLNR'.

field_tab-tabname = 'MSEG'.

APPEND field_tab.

LOOP AT itab2 .

value_tab-mblnr = itab2-mblnr.

APPEND value_tab.

CLEAR value_tab.

ENDLOOP.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

retfield = field_tab-fieldname

TABLES

value_tab = value_tab

field_tab = field_tab

return_tab = return_tab

DYNPFLD_MAPPING =
EXCEPTIONS
PARAMETER_ERROR = 1
NO_VALUES_FOUND = 2
OTHERS = 3

IF sy-subrc = 0.

CLEAR : yr,tp.

itab2-mblnr = return_tab-fieldval.

SELECT SINGLE mjahr INTO yr FROM mseg WHERE mblnr = itab2-mblnr.

iam assuming that u r calling a screen and not doing the changes on default selection screen 1000 as iam not sure the follwing things can be done selection screen 1000 .

on the screen layout draw input/ output fileds and text field( for display)

double click the input/outpurt field and in the screen properties give the field name and make it as list box, give some value in the FCT code say z_hlp.

do it for both the fields where u want to having diff screen field name and different FCT code.

leave the layout and come to pbo module.

if search help has to be populated for a field before any

input by the user it should be done in PBO module of the screen,

by using the fucntion module

vrm_set_values

first populate the internal table with ur search help values .

and then use the above mentioned function module , give the screen name where u want search help(screen name of fileds have already been given by you) and internal tabel ( where the data for search help is already populated.) as parameters of the function module.

now if u wnt to give search help in the second field based on the selected parameter in the first filed.

write code in pai module

if sy-ucomm = fct code of the first field ( fct code is given by u , while making the first field on screen as listbox in screen properties of the field)

again fill the internal table and on bases of value of the first parameter which u can retrive by mentioning the fieldname

select from custom tabel

into intrnal table

where abc = zdm-abc ( screen name of the field).

agin use the fucntion module vrm_set_values... and give the screen name( of second field) and intenal table .
