Hello Videesh,
make a backup from the file DBSIZE.XML in sapinst_instdir and \ABAP\DB\ORA then remove the columns
"policyActionType" and "policyDays" from the original one.
After that please retry the installation with the option continue old
installation.
remove:
<column name="policyActionType">
</column>
<column name="policyDays">
</column>
Regards
Christian
