We are new to SAP. We have SAP R/3 4.6C and BW 3.0B. We want to create a Process Chain in BW to call several ABAP programs in R/3 before executing an infopackage in BW. The BW documentation recommends to create a program or an RFC? local in BW to call the R/3 programs, otherwise the Process Chain will not recognize the completion of the R/3 programs. My question is, how do you create an ABAP program or RFC in BW to execute the ABAP programs in R/3. I have a little ABAP experience, so an example would be beneficial.
