ABAP syntax check: No string calculation permitted here - why?

I have this method:

    ). " equipments.
  endmethod.

On the marked line, i get the syntax error"String calculation not permitted here", but I do not understand, why?

I think I've seen this before - do you get the same error without

alpha=out

To make a long thing short:

DATA:
  BEGIN OF line,
    colt type string,
    coli TYPE i,
  END OF line.
line = VALUE #( colt = 1 + 1 ).
line = VALUE #( coli = `...` ).
line-coli = |...|.
line-coli = `...` && `...`.
line = VALUE #( coli = CONV i( |...| ) ).
line = VALUE #( coli = CONV i( `...` && `...` ) ).
line = VALUE #( coli = |...| ).                    "Error
line = VALUE #( coli = `...` && `...` ).           "Error

Let's say, we have a small flaw in assigning string expressions to incompatible structure components in the VALUE operator.

A workaround is the explicit usage of CONV. Development is notified.

Horst,

"Development is notified".

Is this team into Kernel side Development ?

Just curious to know which side of development handles these kind of issues.

Sure, Kernel development, who else ...
