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

Niranjan
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
