Different Order Types within a Collective Order

Dear PP Gurus,

I have a requirement for having different order types with in a collective order. For example, in a BOM of 3 levels, the order type for each assembly should be different say ZPP1, ZPP2 and ZPP3.

For this, I have maintained separate production scheduling profiles in each of these assemblies with the respective order types. Also, I have maintained MRP groups separately for each of these materials. Further, in Plant Parameters, no default order type is assigned.

However, when I create the order, the system creates all orders with order type ZPP1 which is for the header material.

As per SAP help, this is possible but I am not able to create collective order with different order types.

Please suggest any SAP Note or configuration changes which I have missed out.

Thanks!

With Regards,

Nitin
