Field modification in dialog programming.

[Former Member]

Hi,

I am working on dialog prog for the first time and need your help.

I have z t-code.After executing this I get a screen,which has 3 i/o box

1.Approver name

2.Approver Group

3.Requester name.

The requirement is whenever the approver group is changed the approver name also should change.

But the appover name is not getting altered.

How to achieve this.

The field approver group has a search help associated with it.

Both the fields are from the same z table.

Regards,

POV.

Write code u r wish code in module.

IF approver group changes.

select the data from ztable for the approver group.

approver name = wa_approver name.

endif.

Create a search Help with the fields 1.Approver name 2.Approver Group

Attach it in the Screen attributes - Search Hlp for the field Approver name

IF approver name is entered manually..handle it in PAI on "ENTER"

Hi ,

Write a seperate module to fill the values of approver group and approver name.

PROCESS ON VALUE-REQUEST.

FIELD 'Approver group' MODULE fill_group.

FIELD 'Approver name' MODULE fill_name.

In this module select the values from the database table into an internal table and call FM :

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

retfield = 'Field name'

dynpprog = sy-cprog

dynpnr = sy-dynnr

dynprofield = 'Screen field'

value_org = 'S'

TABLES

value_tab = 'Internal table'

EXCEPTIONS

parameter_error = 1

no_values_found = 2

OTHERS = 3.

In your module fill name - select the approver name based on the approver group into the internal table.

Thanx & Rgds,

Hi ,

I have put the following code.

Now the same field that is the approver group field is getting changed and not the approver name field .

Is this because the approver name field is disabled i.e in output only mode?

MODULE fill_group INPUT.
