What is the most important prerequisite knowledge for a successful migration from ABAP to BW?
The advantages of the ABAP background is you will find it easier to understand the technical aspects of BW, such as when you need to create additional transfer structures or if you need to program any conversion routines for the data being uploaded, as well as being familiar with the source tables from SAP R/3.
The advantage of coming from a functional consultant background is the knowledge of the business process. This is important when you're modeling new infocubes. You should be familiar with what kind of data/information your user needs and how they want to view/group the data together.
Moving into the BW arena is more than just understanding both ABAP and the knowledge of business processes. You will need to understand the aspects of efficient data modeling, process mapping into the right type of data model and also decide what is the most efficient way to manipulate/convert data when uploading within BW.
Nevertheless, having ABAP knowledge is extremely helpful in many ways (like error analysis/debugging, realization of complex scenarios like N:M relations in a data model and variables of exit types).
