Need help with screen programming

[Former Member]

Hi all,

In my screen, I have 2 fields. The first field, I would like to enter some data. The second field, I would like to attach a Search Help depending on the data entered on the first field. How can I do that? Currently, when I try to debug, I found out that when I run the logic to generat the search help, the first field value is not captured, Thanks in advance.

do not write the code under process on value-request.

just write the code under chain endchain.

See the statement

PAI

chain.

field fieldname module modname.

endchain.

module modname.

here you need to write the code.

you can see the first value,pass this value to search help function module

endmodule.

You should write it in the POV Process on Value Request event.

process on value-request.

field ZES_PO_ITEM-ST_PRIOK module GET_PRIORITY_F4.

in the module make use of the FM: DYNP_VALUES_READ. Its a good practice to use the FM. this refreshes you screen filed values.

now based on this you can get the values in the search help by using the

FM: F4IF_INT_TABLE_VALUE_REQUEST

If not you can create a new search help in SE11 and attach it to be table itself at the field level in case of customised tables.

Hi Gopi,

Below is my code

I_FIELDS-FIELDNAME = D_EBELN.

APPEND I_FIELDS.

CALL FUNCTION 'DYNP_VALUES_READ'

EXPORTING

DYNAME = 'ZTEST'

DYNUMB = '0100'

TABLES

DYNPFIELDS = I_FIELDS.

But the field's value (D_EBELN) is still not acquired in the internal table I_FIELDS although the return code is 0. Please advice.

[gopi_narendra]

I_FIELDS-FIELDNAME = D_EBELN.

APPEND I_FIELDS.

CALL FUNCTION 'DYNP_VALUES_READ'

EXPORTING

DYNAME = 'ZTEST'

DYNUMB = '0100'

TABLES

DYNPFIELDS = I_FIELDS.

the i_fields shoudl contain only the screen field names but not any values. It should carry only the <b>SCREEN FIELD NAMES(NOT ANY VALUES) GIVEN IN QUOTES</b>

See my similar code . the declarations are as below.

data : IT_DYNPREAD type standard table of DYNPREAD initial size 0,
       IS_DYNPREAD type DYNPREAD.
data : IT_RETURN type standard table of DDSHRETVAL initial size 0,
       IS_RETURN type DDSHRETVAL.
