A query in module pool

Former Member — Wed, 12 Apr 2006 05:31:23 GMT

hi all,

I have a query in module pool, my problem is

lets say i have two fields in a screen.

out of which one is a date field and other one is a field which has got F4 help.

When i pick some values from the F4 help i have to populate the date field simaultaneously.

EG: when i pick value 1 from F4 help then i have to pass

the date value to screen as soon as i pick.

Can anybody help me out..

Regards,

Krishnakumar

The F4 help is a DDIC search help or custom search help in POH event?

its better to use custom help in POV event for the other field. Similarly populate date field within POV.

refresh : ltab_fields.

ltab_fields-fieldname = 'ZMM_TABLE-TABNAME'.

ltab_fields-fieldvalue = t_f4_table-tabname.

ltab_fields-stepl = step_line.

append ltab_fields.

ltab_fields-fieldname = 'ZMM_TABLE-FLDNAME'.

ltab_fields-fieldvalue = t_f4_table-fieldname.

ltab_fields-stepl = step_line.

append ltab_fields.

ltab_fields-fieldname = 'ZMM_TABLE-VALUE'.

ltab_fields-fieldvalue = t_f4_table-fieldtext.

ltab_fields-stepl = step_line.

append ltab_fields.

call function 'DYNP_VALUES_UPDATE'

exporting

dyname = lc_dyname

Hello Krishnakumar,

I would suggest u can use the following...

read the internal table retun in the RETURN_TAB which will give the value of the selected field. use the field to read the date value in the table value_tab.

use the following code then to update the field..

declare this on top

data: begin of iitab occurs 0.

include structure dynpread.

data: end of iitab.

clear iitab.

refresh iitab.

iitab-fieldname = <first field name>.

append iitab.

iitab-fieldname = <second field name>'.

append iitab.

read table iitab with key fieldname = '<first fieldname>'.

iitab-fieldvalue = update the value of the first field.

modify iitab transporting fieldvalue where fieldname = '<firsr field name>'.

read table iitab with key fieldname = '<second field name>'.

iitab-fieldvalue = <secodn field value>.

modify iitab transporting fieldvalue where fieldname = '<second field value>'.

CALL FUNCTION 'DYNP_VALUES_UPDATE'

EXPORTING

DYNAME = sy-cprog

DYNUMB = sy-dynnr

TABLES

DYNPFIELDS = iitab

EXCEPTIONS
INVALID_ABAPWORKAREA = 1
INVALID_DYNPROFIELD = 2
INVALID_DYNPRONAME = 3
INVALID_DYNPRONUMMER = 4
INVALID_REQUEST = 5
NO_FIELDDESCRIPTION = 6
UNDEFIND_ERROR = 7
OTHERS = 8

IF SY-SUBRC <> 0.

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

ENDIF.
