Dumb question about monodimensional internal tables

Question

Hi all gurus,
in ABAP/4 it is possible to define an internal table made up by a single field , so that we could consider such a declaration:
DATA: itab TYPE TABLE OF EBELN
as a single-dimension array.
Now, supposing I want to fast access this vector directly with a read table... I don't have an explicit field name to refer to in the WITH KEY clause.
My workaround actually is to define such a vector in this way:
DATA: begin of itab,
            doc_no TYPE EBELN,
            end of itab.
so that a fast READ TABLE statement can be possible specifying the WITH TABLE clause in this way:
READ TABLE itab WITH KEY doc_no = <valuetosearchfor>  .
Anyway, I'm wondering if these ops are possible even in an itab defined in the first form, without the need of defining a specific itab structure. In many situation I find mono-dimensional tables really useful, I'd like to avoid every time an explicit DATA type def.

Hello,
I dont know if this is what you are looking for. You can use the addition:
... WITH TABLE KEY [keyname COMPONENTS] ...
SAp documentation also adds:
The pseudo component table_line can be specified as a component for tables with an unstructured row type, if their whole table entry is defined as a table key.
For more details on psuedo components read this : [http://help.sap.com/abapdocu_70/en/ABENITAB_COMPONENTS.htm|http://help.sap.com/abapdocu_70/en/ABENITAB_COMPONENTS.htm]
Hope this helps.
BR,
Suhas
