Mark Walker has been an SAP technical consultant for over 16 years, starting with ERP, in the ABAP programming area, where he specialized in bespoke programming and optimization. Next up came the BW Business Intelligence platform, again specializing in hard-to-implement solutions, especially in the SEM-BPS and BI-IP (integrated planning—or how to write user data into a cube) modules. He's been working with SAP HANA since 2011 just after it was released, and is a certified Application Associate on HANA since early 2012.
