Learn how to migrate your custom SAP NetWeaver 3.x ABAP code used in rules to SAP NetWeaver BW 7.0 without additional coding, thereby saving time and protecting your investment as you upgrade your system landscape.
The Enterprise Data Warehouse (EDW) layer allows you to design your warehouse so that performance does not suffer. You can easily archive and then if you need to make changes, they are easily manageable.
Many companies have vast amounts of custom ABAP code that needs to be migrated to the latest version of SAP NetWeaver. However, since SAP does not provide a tool for migration of custom code I have developed a step-by-step procedure that you can implement to migrate your data flow. It contains custom ABAP routines from the Enterprise Data Warehouse (EDW) layer to the final data targets, including InfoCubes and MultiProviders without manual coding.
Figure 1 depicts the objects that you need to create for the migration and the order in which you should develop them as part of the migration process. Although the data flows in the order that it appears in the figure, the order of the development of the objects must be followed as shown. This is the key for this process to work appropriately.
