In MTO VC scenario, how to deliver subassemblies separately from a sales order

Question

Finished good has two sub-assemblies for the main assembly. The main assembly is not an assembly actually but Customer orders it as Assembled component of Subassembly 1 And Sub assembly 2. There are cases where Sub assemblies can be shipped separately which are then assembled at the Customer Site.
Main FG product and sub-assemblies are both Configurable materials.
In the above scenario which MRP strategy is more suitable and how to dispatch individual subassemblies separately.
Also there should be option to produce subassembly separately if the need arises.
Ex: Box assembly is made of Lid & Pan. All the 3 materials are configurable as per Customer requirement.
Customers order for Box assembly in the sales order
Need to know which is most suitable strategy which can satisfy below req's
1. Box can be produced as assembly and dispactched
2. Lid and Cover can be produced separately and can be assembled at Customer site
3. Delivery of individual LId and cover can be made separately
4. Production order creation should be possible for Box, Lid or Pan separately

Answer 1

Repeating answer since Q is duplicated in two forums:
Hi There,
are you sure that your Item A is a genuine Pick To Order? - I would think that a PTO would result in exploding the OM Line to separate lines for the components and when they are ATO's they individually would result in WIP Jobs.
Anyway once the toplevel Item is resulting in a WIP job the only mechanism for creating the remaining component jobs are via an MRP breakdown done by the classical MRP or ASCP planning run.
To tie the different jobs together (hard-pegging) you would have to look at Project MFG (PJM) e.g. in the simple version of SEIBANs.
