I have an assembly containing a sub assembly and some parts. The sub assembly contains three parts A, b, and c. In the assembly if I am replacing the sub assembly with a new sub assembly containing parts A, d, and c through API, the parts of newly sub assembly are updated in the assembly and the part b also remains in the assembly. Aslo some of the parts of the assembly disapears from it. If I am doing it manually, ther is no problem. Can any body have the idea regarding this problem and the probable solution.
Thanks in advance
