Hello Everybody,

I would like to know what are the fields required to be populated in R/3 system (so that i can see the Safety Stock Method as "MZ" in SAP APO.

"For Example: by maintaining a value of safety stock as quantity in Safety Stock field on MRP2 view, system will automatically set SB as safety stock method in APO"

Similarly i would like to know for "MZ".

Best Regards,

    For Safety stock functions, following standard methods are available in APO:

    Static Method : Parameters are defined in the location product master

    1. SB - Safety stock from location product master

    2. SZ - Safety days's supply from location product master

    3. SM - Max. of SafeStk and safety days' supply from loc. prod. master

    These can be transferred from settings in MRP views in material masters in SAP R/3- ERP to APO through CIF.

    Dynamic Method:

    Parameters are defined on a time-dependent basis; meaning that they are defined individually for each bucket in the planning buckets profile.

    1. MB - Safety stock (time-dependent maintenance)

    2. MZ - Safety days' supply (time-dependent maintenance)

    3. MM - Max. of SafeStk and safety days' supply (time-depend. maint.)

    MZ - Safety days' supply (time-dependent maintenance):

    The safety stock is calculated identically to the SZ method. However, the safety days' supply used is not taken from the location product master data, but rather from a specified key figure on a bucket-dependent basis. Thus, the user is able to manually maintain the safety days' supply for exact buckets.

    I hope this helps to clarify.

    Please confirm .
