Parameter help

Former Member — Tue, 31 Jan 2006 08:58:18 GMT

Hi All,

I have two input parameters in my report. Both have set f4 help using search help objects.

Based on the fisrt parameter's value, i need to execute a select statement and then the second parameter help list should be populated from the resultset.

How can i do this?

Thanks and Regards,

Uma

ex:

declare itab

data : ret_tab like ddshretval occurs 0 with header line.

parametes: a like mara-matnr,

b like mara-mbrsh .

select mbrsh from mara into table itab

where matnr = a.

at selection-screen on value-request for b.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

RETFIELD = 'B'

VALUE_ORG = 'S'

CALLBACK_PROGRAM = V_REPID

TABLES

VALUE_TAB = itab RETURN_TAB = RET_TAB.

REFRESH it_pval.

read table ret_tab index 1.

IF SY-SUBRC = 0.

move ret_tab-fieldval to B.

ENDIF.

Hi Uma,

first read the values(of first parameter) in the selection-screen using the funciton module "DYNP_VALUES_READ" and provide f4 help for the second parameter using the function module "F4IF_INT_TABLE_VALUE_REQUEST" fill the value_tab parameter of this fm with the values based on the values retrieved from the fm "DYNP_VALUES_READ"

Use the FM 'DYNP_VALUES_READ' to read the value in the first parameter and then use the FM

sugggested above.

Thanks a lot for all your replies. But still my f4 help list for second parameter is not getting populated. Here is my code.

itab "itab_product" declaration

SELECTION-SCREEN BEGIN OF SCREEN 0001.

Input Parameters.

parameters pa like tableA-PRODUCT_NAME Matchcode object

ZPRODUCTHELP.

parameters pb like itab_product-PRODUCT_MODEL.

SELECTION-SCREEN END OF SCREEN 0001.

CALL SELECTION-SCREEN '0001' STARTING AT 10 10.

select statement from tableA into itab_product
condition pa=tableA-field1.

AT SELECTION-SCREEN ON value-REQUEST FOR pb.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

RETFIELD = 'pb'

VALUE_ORG = 'S'

TABLES

VALUE_TAB = itab_product.

Where am i gone wrong?

Thanks,

Uma
