Hi Ehab,
please tell us which version of SUM you are using.
It seems that the upgrade procedure didn´t create the table PUTTB_SHD.
This table controls the shadow_import_inc phase during the upgrade. Please double check if this table exists. Please check also the database log, if there are some errors regarding this table.
If there is no newer SUM version for you available, you have to open an OSS message and create the table manually.
Regards,
Jens
