Screen Dialog problem with refreshing.

Hi everyone,

I built a Screen Dialog containing (to simplify) an Input field (in a BOX) and an ALV (in a Custom Cotrol).

In the ALV, I fill two columns : material and quantity.

When pressing on Enter on the quantity field, I get the netwr (total price) from a table. I would like to display this price in the Input field.

In fact, the Input field does get the price value but does not display it to the screen.

I try to use the following function but still not refreshing :

CALL FUNCTION 'DYNP_VALUES_UPDATE'

EXPORTING

dyname = sy-repid

dynumb = sy-dynnr

TABLES

dynpfields = lt_dynpfields

EXCEPTIONS

invalid_abapworkarea = 1

invalid_dynprofield = 2

invalid_dynproname = 3

invalid_dynpronummer = 4

invalid_request = 5

no_fielddescription = 6

undefind_error = 7

OTHERS = 8.

Thanks for the help!!!

Regards.
