Dropdown listbox and dynpro not work in SM30

Hi all,

I have a problem with dropdown listbox and dynpro.

When I execute SM30 on a custom  table, not all values

are showed in the listbox, but it is shown only the

value already in the field.

So I’m not able to change

this value. For example if I want to update a record with

ZFIELD = ‘NSF’, I only see ‘NSF’ in dropdown listbox,

and I cannot write manually anything else, and I can

see only ‘NSF’ in the field listbox.

Before system upgrade, on this custom table I created a table

maintenance generator. In the maintenance

screen, Z field has dropdown set on ‘ listbox’ and the system

worked as expected.

I specify that:

On this table, there is a data element of a Z field with a

data type containing a type char domain with 2

fixed values (SF and NSF). Also this data element has a search

help in further characteristics. In the value

table linked to this field there are 3 values: SF, NSF, blank.

If in the properties field of the maintenance screen I remove

dropdown ‘listbox’ and I set it on blank, I can

see all values and I can update my field too, but this is only

a workaround because in this way I can enter

every values, also not allowed values, i.e. values not included in the value table.
