Low level code determination in APO - PP/DS

Hi,

In our masterdata setup, the PDS has dummy component. The dummy component is replaced by actual cmponent from variant tables at the time of planned order creation in PPDS.

Since in PDS it is dummy component, the low level code determination in our case do not work.

Please suggest how can we determine corectly the low level codes in APO in this case.

Any program or any special heuristics?

Thanks in advance.

Regards,
