The BW Support Package and BW Accelerator revision are not compatible

What causes this issue?

The BW support package and the revision of the BW accelerator on this
system are <ZH>not</> compatible. Whereas the BW system follows the SAP
NetWeaver Support Packages Stack (SPS) strategy, separate revisions with
code enhancements and corrections are made available for the BW
accelerator. These support packages and revisions are generally made
available at the same time. However, some deviations to this rule can
occur. SAP guarantees compatibility between a specific support package
and a specific revision for the BW accelerator. Upward compatibility is
supported for the BW accelerator. The revision of the BW accelerator can
therefore be higher than the revision specified for the current BW
support package. Downward compatibility, however, is not supported.
Problems can occur if the revision is lower than the revision required.
This problem is known to occur in particular just after a new BW support
package is installed when the current revision is not yet installed.
The current revision of the BW accelerator is too low to be used with
this BW support package.
