BOM-structured RFx in manufacturiong industry

Hi,

Do you have the reference of Bidding Engine for direct material sourcing?

Especially in Automotive industry, there seems to be the case RFx has BOM-structured lines of assy.

In SRM Bidding Engine, we can use the "outline" function, but I have never heard this function is used in direct material sourcing in manufacturing industry.

If you have any idea to handle BOM-structured RFx, please share it.

regards,

Tadasuke
