ITAB_STRUC_ACCESS_VIOLATION in tcode CJ20n

Dear Friends,

After upgrade the kernel version from 701 to 721, we are getting short dump error in transaction CJ20N when going for save the data. The program name is SAPLCNPB_M.

We have get the abap dump error message - ITAB_STRUC_ACCESS_VIOLATION.

Before kernel upgrade we did not get any above message.
