Why we need ABAP if we can connect With Crystal Reports to SAP R/3
I am new to Crystal reports.I came to know that we can connect SAP R/3 by using SAP InfoSet,SAP Table Cluster and Function connectivity in Crystal Reports.So we can generate reports for SAP R/3 database with out need of ABAP.So why we need to go ABAP module.Is there any disadvantages if we dont use ABAP to generate reports or we can use always Crystal Reports to generate Reports for R/3 database?

it is correct that you can built a Crystal Report without the need to use ABAP, but we have lots of customers that have invested over the years into ABAP Routines and Crystal REports is able to leverage those as well. So with Crystal Reports you have the choice to leverage existing ABAP Functions as a source for reporting - which might help to leverage complex processing on the backend - or to use InfoSets and tables.
