SAP Error Message - Details

• Message number: 844

• Message text: Add-On update &, version &, release & do not match (high source release)

What causes this issue?

As of Release 3.0, add-on products are imported using a standard
procedure and recorded in the SAP system. On the inserted additional CD
for updating the add-on product, there is an update package that cannot
be used because the source release of this upgrade is not compatible
with this package. This is not generally an error, since there can be
more than one update package on a CD. The suitable package(s) is then
selected from these packages.
