Our current customer has a BOM structure with many phantom assemblies. We are assessing if this structure make create any problem in terms of both planning and system performance in APO. So, my questions are;
1) Are there any disadvantages or restrictions of using phantom assemblies in SNP/PPDS?
2) Does these levels reduce the performance of the system, although phantom assemblies will not be planned but will be used to transfer the requirement from upper level to lower level?
Any comment is appreciated.
