Loading Master Data 
· During the initial download, you must activate number range buffering for the master data ID tables of the following InfoObjects (for more information, see the SAP Market Marketplace under http://service.sap.com):
¡ 0BPARTNER
¡ 0UCBU_PART
¡ 0FC_ACCNTBP
¡ 0CACONT_ACC
¡ 0UCCONTRACT
¡ 0UCINSTALLA
¡ 0UCPREMISE
¡ 0UC_CONNOBJ
· When you activate the master data after the delta upload, the aggregates for the InfoCube must be restructured. You should avoid using aggregates of the target group selection InfoCube. The data model is oriented towards optimal performance without the use of aggregates.
Always load the master data before the transaction data
