Careers in SAP Business Information Warehouse (SAP BW) & Advanced Data Analytics
For a career in SAP Business Information Warehouse (SAP BW) & Advanced Data Analytics, a
strong knowledge of Databases would be required along with
a good knowledge of the underlying SAP Modules at a Functional level.
Getting a certification in SAP BW - SAP courses TBWxx (xx from 10 - 50) is useful if one plans to employ it in a domain similar to one's current experience.
Knowledge of Crystal Reports would help as it is currently
integrated into SAP BW to enhance SAP Business Explorer (BEx)
which is a SAP Business Information Warehouse component
for detailed reporting and analysis.
Related to the above, Business Intelligence (BI) is a safer Horizontal (Non Industry Specific) option. However, for the same, deeper & broader technical skills are required.
