System Fields in Release 6.10
1. Content of the system field sy-calld
2. Replacement of the system field sy-repid
Other versions: 7.31 | 7.40 | 7.54
Modification 1
Content of the system field sy-calld
The field sy-calld should contain space if the program is the first and only program in a
call sequence.
sy-calld should contain "X" if the program is a called program
in a call sequence. Previously, sy-calld was always set to "X" for SUBMIT without RETURN, even though this meant that the
internal session or
the position in the call sequence of the caller is replaced by the called program. If the calling program
was the first program in the call sequence, this produced errors in the application logic. From now
on, sy-calld is not influenced by SUBMIT without
RETURN, and retains the value of the calling program whose internal session is being replaced.
Modification 2
Replacement of the system field sy-repid
The system field sy-repid is no longer a component of the structure SY in
the ABAP program or the structured type SYST in ABAP Dictionary. Instead, from Release 6.10, every program
contains the predefined constants sy-repid and syst-repid,
which both contain the name of the current program. There are also two predefined types sy-repid
and syst-repid. The obsolete type references
LIKE syst-repid and TYPE sy-repid are, therefore, still possible.
In addition to considerable performance improvements in the external procedure call, this new feature also has the advantage that sy-repid can now also be passed as a parameter to external
procedures. The formal parameter is set to the name of the caller and not to the name of the
master program, which means that an auxiliary variable is no longer required.
This incompatible change can cause problems if ABAP programs refer to the previous structure syst, for example:
-
DATA my_syst type syst.... my_syst-repid ... -
ASSIGN COMPONENT 'REPID' OF STRUCTURE sy TO ...
