problem with matchcode in alv for specific field

Former Member — Tue, 18 Aug 2009 14:44:08 GMT

Hi,

I have created a customer specific data element ZE_CONFTYPE, with a customer specific domain, and in this domain I have defined a value range with 3 possible single values (partial, final, automatic).

Later, I have defined a field: CTYPE type ZE_CONFTYPE, and I'm showing this field in an ALV.

it_fieldcatalog-fieldname = 'CTYPE'.

it_fieldcatalog-seltext_m = 'Confirmation Type'.

it_fieldcatalog-col_pos = 4.

it_fieldcatalog-edit = 'X'.

APPEND it_fieldcatalog.

CLEAR it_fieldcatalog.

Now I was hoping that a matchcode was going to show up in the ALV with the 3 possible values for this field, but apparently I was wrong. What should I do for this matchcode to show up?

THX!

In the field catalog you may need to provide

ref_fieldname

ref_tabname

Then you may need to use


  call function 'REUSE_ALV_GRID_DISPLAY'
       exporting
            i_callback_program       = repid
            i_callback_user_command  = 'CALLBACK_FOR_DETAIL'
            is_layout                = is_layout
            it_fieldcat              = ct_fieldcat
       tables
            t_outtab                 = g_itab.

You need to write code in "callback_for_detail" with fm F4IF_INT_TABLE_VALUE_REQUEST

Create a structure with the field you mentioned and give structure name as ref_table and field name as ref_fieldname

Thanks for your reply.

I created a structure as you said, with only the field CTYPE,

and defined the structure as ref_tabname and the field as ref_fieldname.

Now when I execute the program, the matchcode does show up,

but when I click on it, I get a dump: "field symbol has not yet been assigned."

Would I have to create a table instead of a structure?

Isn't it weird that I can't show a matchcode with the fixed values of a custom field in an ALV without having to create a table for it?

In a selection screen this would work.

After creating a table, the matchcode doesn't show up either.
