Issue with Activity Rates
This issue was caused due to an issue in the activity "Assignment of
Values to Selection Groups". I was able to replicate the issue in our
internal test systems and we have released a note to fix the same. The
note for this issue would be 2042000. For the current package, to fix
the issue you would have to re-transfer the table CSSL in full using
DB tools. For the future packages you could apply the above mentioned
note before the start of the package and this issue should not occur.
