ABAP 7.40: Accessing a part of a shifted field

[ralf_wenzel_heuristika]

Hi,

I am still in trouble with ABAP 7.40, sometimes

DATA:
   charact TYPE c LENGTH 10 VALUE 'BLABLABLUB',
   target  TYPE c LENGTH 10.

target = shift_right( val = charact circular = 4 ).

IF target(4) EQ 'BLUB'.
* ....
ENDIF.

I'd like to have an alternative coding without field "target", which is needed for "target(4)"-expression. What I mean is a

IF shift_right( val = charact circular = 4 )(4) EQ 'BLUB'.  " <= of course, this does not work

* ....
ENDIF.

Anybody out there, who can help me?

Hi Ralf,

please try

If shift_right( val = charact circular = 4 ) CP 'BLUB*'.

Regards,

Klaus

It's so simple..... *argh

Hi Klaus. Would you know why doesn't (4) work?

[SuhaSaha]

Dug up SAP documentation and there are apparently 3 operand positions -

• read,
• write
• subfield access

String processing functions e.g., shift_right, can only be declared at "reader" positions.

Neither did SUBSTRING work
