general issue in module pool

[Former Member]

I am working on dialog program.

i have a provide a f4 value for one of the field.

lats say i have two fields field A

field B

I have to provide f4 help fir field B.

I have a ztable which have field A and field B .

FIELD A is primary key.

based on my input for field A i have to retrieve values FROM ZTABLE FOR FIELD B

I HAVE DONE THE SAME.

WHEN I ENTER VALUE FOR FIELD A and then f4 for field B IAM NOT ABLE TO RETRIEVE ANY VALUES BECAUSE

process on value-request.

FIELD ZTEST-A MODULE VALUE_REQUEST.

SELECT * INTO TABLE ITAB FROM ZTEST

WHERE A = ZTEST-A.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

• DDIC_STRUCTURE = ' '

RETFIELD = 'B'

• PVALKEY = ' '

• DYNPPROG = ' '

• DYNPNR = ' '

• DYNPROFIELD = ' '

• STEPL = 0

WINDOW_TITLE = 'TEST'

• VALUE = ' '

VALUE_ORG = 'S'

• MULTIPLE_CHOICE = ' '

• DISPLAY = ' '

• CALLBACK_PROGRAM = ' '

• CALLBACK_FORM = ' '

TABLES

VALUE_TAB = ITAB

• FIELD_TAB =

RETURN_TAB = IT_RETURN

• 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.

WHEN I PRESS F4 FOR FIELD B ,MY FIELD A IS INITIAL.

AFTER GIVING FIELD A VALUE AND THEN PRESS ENTER AND THEN PRESS F4 FOR FIELD B THEN IT WORKS FINE.

BUT THE USER DON'T WANT TO PRESS ENTER AFTER GIVING VALUE FOR FIELD A.

I ALSO WANT TO KNOW, IF I PRESS F4 DOES THE CONTROL DIRECTLY GOES TO POV OR DOES IT GOES THROUGH PAI AND THEN TO POV.

Any lead or suggestings in achieving this would be great

Thanks

use 'DYNP_VALUES_READ' fm to catch the value and then use this in F4_XXXXX_helprequest -fm
