ECM Parameter effectivity used with BOM in not working fine using PRs and POs

[former_member668570]

Hi SAP Community,

We are woking on a scenario where there are BOMs managed by change numbers. These change numbers are also ECM controlled using a parameter by serial number. Everything is working fine in production area. MRP is launched and system identifies what is the correct BOM structure taking into consideration serial numbers and this means system is finally able to creates the expected planned orders with the correct structure. Whether we create manually production orders via CO01, system is also working fine, showing us a pop-up window where we can introduce the specific serial number before to explote the BOM. But this funciontality is not present on PR and PO for subcontracting. Do you know whether ECM is ready to work in purchasing flows?

Thanks in advance.
