Was verursacht dieses Problem?

The handling of compressed records in flat inventory cubes is different
from classic Star Schema InfoCubes. Due to a program error, flat
inventory cubes in BW (based on DB2 for IBM i) were compressed using the
wrong method.

Systemantwort

The compression of flat inventory cubes in BW (based on DB2 for IBM i)
was corrected and now uses the newest method "Reference-point update
version 2".
In order to avoid creating inconsistent data, flat inventory cubes,
which contain records compressed by the old method, cannot be compressed
anymore.

Wie behebe ich diesen Fehler?

When compression starts, BW checks whether the InfoCube is using the
correct method. If this is not the case, it automatically converts the
data of the InfoCube before it continues to compress new requests.
This automated conversion could not be performed. The InfoCube has not
been converted to the correct compression method and therefore it cannot
be compressed.
If you have switched off automated conversion during compression via
RSADMIN parameter RSCDS_NO_CONVERT_TO_REFP_UPD2 = X (not recommended),
then use report RSDD_SWITCH_NCUM_HANDLING_DB4 to convert the InfoCube.
If another problem prevented a successful conversion, check the
application log of the compression or contact SAP support to help find
the cause of the error.
