Uploading Data from OLTP Systems
This step incorporates the usual extraction of vendor and/or customer master data either from the SAP R/3 system (tables LFA1 and KNA1) or other third party administrator source systems in BW. If the vendors/customers have already been enhanced with D-U-N-S numbers in R/3, the D-U-N-S numbers will likewise be uploaded to BW. For the loading process, the respective match recommended flag Matchingshould be set in the transfer rules.
The upload is a prerequisite for all subsequent steps.
