Creation and Deletion of Safety Stock in SAP liveCache (new)

Use

Up to now, the safety stock for a location product was only a virtual requirement; in other words, a requirement that does not exist in SAP liveCache and which is only taken into consideration by the net requirements calculation and not by dynamic pegging in Production Planning and Detailed Scheduling (PP/DS). The system cannot therefore link receipts, which are created in procurement planning in PP/DS to cover safety stock, with the virtual requirement. This affects all functions that evaluate dynamic pegging relationships; for example, the system creates "incorrect" surplus alerts because of non-existent pegging relationships for receipts that have been created to cover the safety stock, or the system cannot take the requirements dates/times of the safety stock requirements into consideration when optimizing the delay costs.

As of SAP APO 4.0, the standard heuristic SAP_PP_018 Create Safety Stock in SAP liveCache (algorithm /SAPAPO/HEU_PLAN_SAFETY_STOCK) is available for make-to-stock production scenarios. You can use this standard heuristic to create, adjust, and delete static safety stock requirements in SAP liveCache. In the standard system, the static safety stock requirement is represented by an order that consists of a requirements element with the category SR. Depending on the planning version, the system takes the safety stock requirements in SAP liveCache into consideration in the net requirements calculation and in dynamic pegging, if you have selected the new option Consider Safety Stock Requirements in SAP liveCache in the field PP/DS: Take Safety Stock into Account in the planning version.

Using the BAdI /SAPAPO/RRP_SFTY_STK (UPDATE_IO_NODES method), you can extend the heuristic for non-make-to-stock scenarios and for the implementation of safety stock methods.

Capable-to-Match (CTM) and Global ATP can take the safety stock requirements in SAP liveCache into consideration. These safety stock requirements are not relevant for safety stock planning in Supply Network Planning (SNP).

Effects on Customizing

If you want to plan using safety stock requirements in SAP liveCache, you check the settings in the SAP standard heuristic SAP_PP_018 in Customizing for Production Planning and Detailed Scheduling under Maintain Heuristics. If you want to use your own settings, you create your own heuristic with the desired heuristic settings by copying the heuristic SAP_PP_018, for example, and changing the settings.
