Hi Ster,
Code a tableview in the layout which is displayed on selection of 12141101   .
In the iterator class , create a new method CONSTRUCTOR , in which you have to poulate internal table for DDLBS of valuedesc(all values required in ddlb like red/purple/orange/12 inches/14 inches/32c etc.) ,as described in the weblog.
For currency, we are again only interested in handling the Edit mode. For this, we want to render a dropdown listbox. There are a number of techniques to fill the data. For this test, we created a name/value table (type TIHTTPNVP) in the class constructor, and already filled it with the currencies that we support. A reference to this table is stored in m_currencies_ref (ABAP statement u201CGET REFERENCE OF var INTO refu201D).
the code will look something like:
data: wa type ihttpnvp.
wa-name = 'Red'.
wa-value = 'Red'.
append wa to itab_valdesc.
wa-name = 'Purple'.
wa-value = 'Purple'.
append wa to itab_valdesc.
wa-name = 'Orange'.
wa-value = 'Orange'.
append wa to itab_valdesc.
wa-name = '12 Inch'.
wa-value = '12 inches'.
append wa to itab_valdesc.
wa-name = '32 C'.
wa-value = '32 C'.
append wa to itab_valdesc.
get reference of itab_valdesc into m_valdesc_ref.
you have to use this refrence table m_valuedesc_ref in the method RENDER_CELL_START to fill the DDLB .
Hope it helps.
