As per sequence maintained access in access sequence, the system is determining correct value for the condition from access 20. Further newly, added condition table in access 40 is working well and there is no issues like Access not made (initialized field). Which you are facing in access 10. So, why you are not getting access 40 value in sales doc, b'coz access 20 is active. If you are a SD Consultant, then you might be aware that access in access sequence are arranged in specific to general key combination. But, frankly, your access seems messy.
So, what is the issue in ZEXC? What is the result your are expecting?
