Problem with reading Dynpro fields

Hi,

I have some tabstrips. On each tabstrip, I have a

container for an ALV and on the bottom I have another

subscreen for some input fields.

Under the subscreen I have some buttons to insert, delete

etc...

The fields in my subscreen I have bound to DDIC table

fields and I have defined that in my program under TABLES

in my declaration.

So when I write something in the fields, their content

has been written to my table-structure defined in TABLES.

If you double click on a line in the alv, the content of

the line has been written to my dynpro fields in the

subscreen.

My problem now is:

When You have double clicked a line and the content was

filled in my dynpro fields and I change the values after-

wards, I do not have the changed field content in my

TABLES structure. It´s because, the framework isn´t

processing my PBO of the subscreen.

How can I call the pbo manually to get the new field

content, when I´m pressing the button on the parent

dynpro?

I hope it´s possible to understand my problem!

Cheers Arne
