Sriram,
Thanks for the information.
The note 1910297 - ABAP Update halted in preprocessing step mentioned to reset the update and apply the patch.
Am in 37 Patch level higher than the version. However the error is smilar to the one mentioned in the note.
I just got this error for 2 tables only not for many tables. These tables related to SLO.
Regards,
Raja. G
