Constructor operator VALUE and its usage.

Hi,

I have used the constructor operator VALUE in the following way:

The above screen-shot works perfect!

Now I noticed that we can't define the table type as generic and must be defined as one with a KEY for the syntax to work.

Why can't we also use a work area instead of internal table based on a line type after VALUE keyword to work in ABAP? It seems that is not supported! Does anyone know how this works or is it me who is making any sort of mistakes?

Many Thanks,

Tanmoy

As of ABAP 740, the table without the key specification is obsolete. See the last lines:


Starting with release 7.40 you declare your standard tables either with a good key or an empty key but never with the chancy default key!

Since VALUE operator is also introduced in ABAP 740, it uses stricter check and doesn't allow with a table which doesn't have key specification.

Now for the VALUE operator for the Structure, which you referred as WA, it also works as

From ABAP Help:

TYPES: BEGIN OF t_struct,

col1 TYPE i,

col2 TYPE t_col2,

END OF t_struct.

DATA: struct TYPE t_struct,

col2 TYPE t_col2.

struct = VALUE t_struct( col1 = 1

col2-col1 = 1

col2-col2 = 2 ).
