Details
If the attribute value is "empty or null" in Teamcneter then NX is showing the previously saved attribute value.
Solution
To display "Empty" or "Null" value of the attribute in NX, user needs to add "/allow_null_value" in the attribute mapping file then only the value is updated.
Ex:
MASS : NR(UGPART-MASSPR).mass /master=none /description="Mass (kg)" /allow_null_value
