We have standard Material Master 0material which is not source sytem compounded. What is the ideal way to load masterdata from different source systems of ECC to a single BW System. Each time when the masterdata is loaded it is over written. We have a situation with same Material ID in both the source Sytem but with different attributes. Is it a good practice to use Consolidated Infoobjects without doing any change to standard infoobject 0material. The same issue is with 0VENDOR, 0CUSTOMER etc.
