Sandeep check this one already.
He suggested to user 2 way.
1. If you want to set B1 in TZ647, you should be channge table setup in T6696 also.
2.Remove B1 form TZ647 and don't change anything in T6669 als
Afterthat, I will talk with K.Kookai, she choosed choice 2.
But before remove, she want to know "What is meaning of "B1"?" And "Why we can remove B1? System doesn't impact on it?
