Hi Yateesh,
Thanks for providing your helping hand once again. I have raised it with SAP and they have provided the below notes for dump
2041631 Simplified Shopping Cart:Dump on Check Out From Catalog
2086844 Dump "Buffer table not up-to-date" on Check Out from Catalog
I am in the process of implementing those notes and I will keep you updated.
Best Regards,
Bharathi
