8 Tips for Implementing a Statistical Forecast in SAP Sales and Operations Planning
Reading time: 3 mins
A very simple statistical forecast method, Time Series, is available in SAP Sales and Operations Planning (S&OP) 3.0 powered by SAP HANA, Support Package 01, which is required for an S&OP process. Based on my experience with S&OP powered by SAP HANA, I share the following tips for implementing a statistical forecast:
- For triple exponential smoothing, historical periods, and historical error period, select twice the number of seasonal periods.
- For single and double exponential smoothing, at least two historical periods are required.
- Historical error periods should be less than historical periods.
- In the statistical forecast job log, users face difficulty reading the error. To do the error analysis, they need help from an SAP HANA developer. To read the errors, an organization may need to develop custom-defined reports.
- S&OP powered by SAP HANA’s planning cycle performance has improved, and now the demand planning cycle time can be shortened.
- New product introduction’s impact on supply requirement, manufacturing, and profitability decisions can be taken in S&OP meetings quickly by collaborating with the demand planner, supply planner, and finance manager.
- SAP HANA PAL forecast methods can be integrated and made available in S&OP HANA by defining a planning operator.
- Integration testing and customer acceptance testing have to be done regressively.
