Extended Safety Stock Planning (Enhanced)

Use

Supply Network Planning (SNP) offers standard safety stock planning and extended safety stock planning. The following changes and enhancements have been made to extended safety stock planning for SAP APO 4.0:

  • A relative forecast error can be entered directly
Extended safety stock planning in SNP uses the relative forecast error of demand and replenishment lead time (RLT) as information about the "uncertainty" of demand and RLT forecasts. The larger the relative forecast error, the higher the amount of safety stock required to achieve a predefined service level. Before now, the system calculated these forecast errors using historical data that you made available in a key figure.
As of SAP APO 4.0, you can specify the forecast errors directly in the location master. SAP recommends that you do this if one of the following applies:
  • There is no historical data (because the product is new, for instance).

  • There is so little historical data that it is not possible to calculate a statistically significant forecast error.

  • The forecast error can be said to be almost constant.

  • Fixed lot size can be considered for the location product
If you are using extended safety stock method BS (beta service level), the system needs to have information about the quantity to be procured. Previously, the system calculated this quantity without taking into account fixed procurement lot sizes.
As of SAP APO 4.0, you can choose that you want the system to take into account the fixed lot size defined in the location product master. To do this, set the relevant indicator in the safety stock planning function. The system then rounds the procurement quantity to the nearest multiple of the fixed lot size.
  • Local time zones can be considered
The critical replenishment channel (the channel with the longest replenishment lead time) is calculated during extended safety stock planning. Previously, this calculation would have errors if the locations of the replenishment channel were in different time zones.
As of SAP APO 4.0, the replenishment lead time calculation is able to consider local time zones properly.
  • Results are saved in time series key figures
Previously, an auxiliary key figure called SAFETY was used to save the results of safety stock planning. Users could also define their own auxiliary key figures for this purpose.
As of SAP APO 4.0, you have to specify a key figure that you created in the time series liveCache for saving the results. This means you can no longer use auxiliary key figures. You can only continue to use the standard 'SAFETY' auxiliary key figure for the standard safety stock planning method.
  • Use of selection ID
Previously, you had to manually select the products and locations you wanted to plan every time you executed safety stock planning.
As of SAP APO 4.0, you can now enter the ID of a selection that you stored in interactive Supply Network Planning (selection ID). For more information, see release information: Using Selection IDs in SNP Background Processing.
