converting PP/DS PPM to SNP PPM

Hai,

BOM and Routing together from ECC when transferred through CIF becomes PPDS PPM in APO. This PPDS PPM is then converted to SNP PPM in /SAPAPO/PPM_CONV. Not all resources, operations and activities are copied to SNP PPM.

My question here is "What is the criterion for this conversion?" While conversion,t he system only considers the production activities and standard costs only. Is that correct? Also the resource with the lowest cost is considered I guess. Can somebody explain me what actually happens during the conversion and I appreciate any documentation pointers.

Thank you.
