RSPO_CACHE_CONTROL sets SY-MSGNO to space
[cache control] [Control] [in control] [out of control] [spool]
Symptom
The C-Call RSPO_CACHE_CONTROL, used for many ABAP-kernel interactions in the BC-CCM-PRN area, incorrectly initializes the system field
SY-MSGNO
with spaces, instead of ‘000′
This can cause an ABAP short dump when an ABAP program tries to output a message stored in these system fields.
One example where this causes a dump is transaction
/DSD/VC_VP_CREATE
when used with SAPgui for HTML
Other terms
Spool,
Reason and Prerequisites
Bug in kernel.
Solution
Fixed with NW 8.0
Fix from 640 kernel on via kernel patch.
