Hi,
i also got same issues after upgrading the kernel from 700 to 721,
i gone through the below steps and my issue has been resolved ,
after kernel upgrade i was getting dumps when i run the Tcodes SM66, St03, ST02
Inconsistency in length of DDIC data type "SWNCGLAGGTASKTYPE".
then i applied the Note " 1610716 - Correcting runtime objects with the wrong alignmen
after applying the Note i have executed the Report : RUT_NOTE_1610716 though SE38 with Option
PCHECK try to run in Background,
then re-run the report with REPAIR
After Repair all Tcode are working fine, but again i am getting dumps " READ_BAD_KEY_ALIGN " with Functional then i have applied the below 2 Notes after that my issues has been resolved.
