F4 help for custom table field - to be used when populating data thru SM30

[Former Member]

Hi,

I have a custom table with 5 fields - say A, B, C, D and E. While populating data to the table through SM30, I need to create a F4 help for the field C. A custom function module needs to be used.

I have created a module for the same in the event PROCESS ON VALUE-REQUEST of the function group of the table.

But the F4 for field C depends on the values put in fields A and B.

I am not able to get the values of fields A and B from within the module PROCESS ON VALUE-REQUEST.

Please help me to create the F4 help.

This is the piece of code i have used in one of my SM30 to get f4. mopdify according to ur need and use.

revert back for further help.

w_dynpread-fieldname = 'ZSITEDCDATA-SITE'.

APPEND w_dynpread TO i_dynpread.

CALL FUNCTION 'DYNP_VALUES_READ'

EXPORTING

dyname = 'SAPLZSITEDCDATA'

dynumb = sy-dynnr

translate_to_upper = 'X'

TABLES

dynpfields = i_dynpread

undefind_error = 8

double_conversion = 9

stepl_not_found = 10

OTHERS = 11.

IF sy-subrc <> 0.

• MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

• WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

READ TABLE i_dynpread INTO w_dynpread INDEX 1.

IF sy-subrc IS INITIAL.

SELECT land1 FROM t001w

INTO TABLE i_site

WHERE werks EQ w_dynpread-fieldvalue.

IF i_site[] IS NOT INITIAL.

DATA: lv_line TYPE i.

CLEAR lv_line.

DESCRIBE TABLE i_site LINES lv_line.

IF lv_line GT 1.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

retfield = 'ZSITEDCDATA-SITE_COUNTRY'

dynpprog = 'SAPLZSITEDCDATA'

dynpnr = sy-dynnr

window_title = 'Site Country'

value_org = 'S'

value_tab = i_site[]

return_tab = i_return

EXCEPTIONS

zsitedcdata-site_country = w_return-fieldval.

ENDIF.

ENDIF.

Hi Gaurav,

This did not work... May be because I need to create the F4 help for the field during populating data in the table through SM30..

I could not get the values in the fields A and B..

[SuhaSaha]

I was wondering if a custom search help can help. Unfortunately i don't have SAP access at this point of time so can try it out.

Hi Suhas,

Actually I cannot make any custom search help.... need to do it through coding in the function group of the custom table.

Hence the problem...

Hi,

Generally making changes to the code of table maintenance is not appreciated because it might be lost once the TMG is regenerated or deleted.

You can go for a custom serach help and attach it to the data element of the table.

But if you want to attach a search help through code modification,

then check ,
