Search help question

Former Member — Sun, 22 Jan 2012 05:37:23 GMT

Gentlemen,

I need your advise.

I have a requirement that a field should have different search-helps based on content of the other field of this screen.

These two fields belong to different structures. What options do I have?

Thank you.

Suppose you have two fields:

Field_1 --- Content of this decides the content of search help of Field_2

Field_2 --- This one has search help

AT SELECTION SCREEN ON VALUE REQUEST FOR Field_2.

1. Fill the internal table you pass to the custom search help conditionally based on the values of Field_1.

2. Pass this internal table to the FM that you use to display search help.

Hello, you need to use DYNP_VALUES_READ FM to read values from screen . and then use it on value request event. please search SDN with this FM. you will find many threads for how to use this... even do a where used list in SAP itself, you will get plenty of examples

Thanks for quick response.

I think I need to elaborate on this topic a little.

First, I'm talking about regular screen, not selection screen.

I'm also aware about DYNP_VALUES_READ.

How to determine content of other field on the screen is not a question.

The question is how to change search help assigned to screen field dynamically. Requested collective search-helps are already defined in DDIC.

I don't want to create complex search-help exit FM that will duplicate logic of these search-helps.

Is there any other alternatives?

I think you can choose this FM F4IF_FIELD_VALUE_REQUEST. directly pass the search help name to it.. (call back program and FM are needed to return back to the program).. just do a where used list.. you will be fine

Dear Vadim,

follow this code.

it helps you to create custom Help.

REPORT zdemo .

TYPES:BEGIN OF ty_lfa1,

lifnr TYPE lfa1-lifnr,

END OF ty_lfa1.

DATA: gt_lfa1 TYPE STANDARD TABLE OF ty_lfa1,

gs_lfa1 TYPE ty_lfa1.

PARAMETERS:vendor(10) TYPE c.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR vendor.

SELECT lifnr FROM lfa1 INTO TABLE gt_lfa1.

IF sy-subrc EQ 0.

SORT gt_lfa1.

ENDIF.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

DDIC_STRUCTURE = ' '

retfield = 'LIFNR'

PVALKEY = ' '

DYNPPROG = sy-repid

DYNPNR = sy-dynnr

DYNPROFIELD = 'vendor'

STEPL = 0
WINDOW_TITLE =
VALUE = ' '

VALUE_ORG = 'S'

MULTIPLE_CHOICE = ' '
DISPLAY = ' '
CALLBACK_PROGRAM = ' '
CALLBACK_FORM = ' '
MARK_TAB =
IMPORTING
USER_RESET =

tables

value_tab = gt_lfa1

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

IF sy-subrc <> 0.

MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.
