Assign documentation as BOM item in a BOM of Raw material

Hi Everyone,

My customer used to assign documentation as BOM item... even for raw material in their old ERP system, that means for raw material, they will also have BOM, the BOM item will be documentation.

For SAP, normally we assign the documetation to the material master data. If we also assign the documetation as BOM item for raw material BOM... will there be any impact for the other business process?
