Hello Rajani,
can you please specify what you are looking. Maybe you should specify, what is your role in SAP ByDesign (end user/ consultant?).
A good starting point is to start on the official SAP help page: SAP Business ByDesign – SAP Help Portal Page.
Here the following link might be a good starting point.
If you need more details get in contact with SAP Consulting or SAP Partners.
Business ByDesign Software Solutions | Cloud Computing | SAP
Best regards
