Hi Kavitha,
With respect to your ABAP dialog instance, there isn't much you need to do. The support packs are contained in the database, so the only real change is the kernel update that typically comes with a stack update. Assuming you have everything set up appropriately, your dialog instances should update their kernels automatically the first time you start them after applying the kernel update to the central instance. However, you'll want to double-check that by comparing versions between the instances.
Regards,
Matt
