Safety stock requirements in Live Cache

[Former Member]

Hi

In Planning version management, There is an option of 'Take Safety stock into Account'

I have clicked the same as I want to use Safety Stock as a requirement in CTM.

The help says, " Using Heuristic, you create Safety stock requirements in Live Cache , base on the algorithm /SAPAPO/HEU_PLAN_SAFETY_STOCK."

Please tell me where do I run this algorithm.

thanks

Hi Niranjan,

The algorithm /SAPAPO/HEU_PLAN_SAFETY_STOCK corresponds to the SAP standard

heuristic SAP_PP_018.

The function of this algorithm is as follows:-

In the standard system, it is defined in the Take Safety Stock into

Account field in the planning version that Production Planning and

Detailed Scheduling (PP/DS) should take safety stock into account as

virtual safety stock elements. In this option, the safety stock of a

product is represented by requirement or receipt elements, which PP/DS

only takes into account during the net requirements calculation, but

which do not exist in SAP liveCache as orders. Therefore, dynamic

pegging cannot take the safety stock elements into consideration and

does not create pegging relationships to these elements. All functions

that evaluate dynamic pegging relationships are affected: For example,

because pegging relationships do not exist for receipts that were

created to cover the safety stock, the system creates "incorrect"

overcoverage alerts, or the system is not able to take the requirement

dates/times of the safety stock requirements into account during

optimization of the lateness costs.

In the standard system, you can only implement this option in a

make-to-stock production scenario and for static safety stock methods

To create the safety stock requirements in SAP liveCache, you use a

heuristic that is based on the algorithm /SAPAPO/HEU_PLAN_SAFETY_STOC

If you have selected the option Create and Adjust Safety Stock

Requirements in the heuristic settings, the heuristic creates an orde

in SAP liveCache for the safety stock of a location product. This ord

has the category GC_OM_SAFETY_STOCK, it consists of a requirement

element with standard category SR, and it represents the safety stock

requirement. In the standard system, the safety stock requirement is

equal in amount to the current amount of static safety stock in the

location product master.

Hi Niranjan ,

Check whether your planning book has the key figure 9asafety. If so use tcode /n/sapapo/msdp_sb to calculate the safety stock value and populate the 9asafety key figure.

In case your planning book does not have the 9asafety key figure you have to use the standard planning book 9asnp_ssp and calculate the safety stock value.

Refer OSS notes 617567 and 504253 to get an idea about the various standard and extended s.s methods and to get an understanding of the various settings required in product master for s.s planniing.

Thanks
