creating F4 help with restricted values

Former Member — Thu, 26 Oct 2006 11:54:59 GMT

Hi,

I created a table and table maintenance program.

The table consists of a few fields.

When inserting new lines, the user should fill the first value and the value he fills should determine

the range of values for the second field.

How can I implement restricting the range of values of the second field based on the selection of the first field?

Thanks.

Promise to award points...

Ruthie.

Hi,

This sample code will help you.It will deal with F4 help for a field.You can two similar code for your requirement.

PROCESS BEFORE OUTPUT.

PROCESS AFTER INPUT.

FIELD s_begru MODULE abc ON INPUT.

Process on value-request.

field s_begru module f4_help.

REPORT ZZZ_JAYTEST1 .

tables kna1.

data:

begin of t_values occurs 2,

value like kna1-begru,

end of t_values,

t_return like ddshretval occurs 0 with header line.

data s_begru like kna1-begru.

call screen 9000.

&----

*& Module f4_help INPUT

&----

text

----

module f4_help input.

*do your logic to populate t_values

call function 'F4IF_INT_TABLE_VALUE_REQUEST'

exporting

retfield = 'BEGRU'

value_org = 'S'

tables

value_tab = t_values

return_tab = t_return

exceptions

parameter_error = 1

no_values_found = 2

others = 3.

if sy-subrc = 0.

read table t_return index 1.

s_begru = t_return-fieldval.

Dear Jayanthi,

I am familiar with the code you wrote.

But - how can I combine the code of the screen with a database system table?

Thanks.
