d. Customer master data (30 min run time)
e. Vendor master data (60 min run time)
f. Product master data (60 min run time)
g. Other Master data (2 hour run time)
Finance and Order cubes cannot run together.
2) Above cubes are used by NA and EU users, NA users will only use NA data and EU users will use only EU data but Master data is common for both NA and EU. The requirement of availability stays same for NA (6AM CST) and for EU reports/cubes should be available by 6am CET.
