How to define the purchase part

Hi everyone,

We just have launched AX system. At present, from purchase department, it is not easy to use the BOM for purchasing in AX now. We have the problems:

  1. Too many layers, same material cannot be automatic calculated together. It spent a lot of time to check one by one at each layer, really difficult to use them directly for purchasing.
  2. Some items it is difficult to know to produce in housing or directly purchase due to miss further definition.

So who can tell how to get the standard solution from AX. How to define the purchase part, how to use master plan.

Thanks,
Jone
