Reg:-SNP-Safety day's supply with Period(weekly) lot size

Hi All,

I have an issue that the Lot-size in product master is Weekly lot size and no min.lot size maintained.Also safety day's supply is 10days.Now If I run Location Heuristics system is generating PR's daily instead of weekly based on my daily forecast tried the same SKU with Weekly size and maintained a min.lot size and removed the safety day'supply .Now it is giving correct results.Is there any condition that periodic lotsize to be maintained without safety stock?Pl.clarify.

Thanks&Regards

    Hi Venkadesh,

    Normally, Weekly lot size will work with safety days of supply. Please try maintaining weekly lot size, mini lot size alongwith safety days of supply and then re-try this scenario.

    Please let me know your observation.

    Regards

    Hi Venkadesh,

    I could suggest the following

    1) As you say, this error is happening only for two SKU's, it shows this is not a configuration error but only master data missing error. You can take out few good SKU's and compare thoroughly with the error SKU's and find out any major master data changes both in R/3 and in APO. If any, correct it according to good SKU's and re-run and check it up.

    2) Check is there any inconsistencies in data between both the systems for those two sku's. If any, correct those using CCR report

    3) Check any rounding value existing for these products

    4) Run heuristic in background for those products and check in inbound/outbound queues and application logs whether you are getting information/error/warning messages.

    Please confirm.

    Regards,

    Hi Venkadesh,

    I have tried your scenario in my system by maintaining periodic weekly lot size, safety days of supply (using SZ method) without maintaining minimum lot size, it is working fine. Later, I tried the same scenario by maintaining min lot size, but it is not honouring min lot size.

    Normally, periodic lot size will work with SZ method. In case, if it not working, there has to be some other setting which is missing.

    Please confirm.

    Regards

    Hi Venkadesh,

    I have maintained forecast on a daily bucket upto 10th may and then run the scenario with periodic lot size, min lot size, safety days of supply 10 days, SZ method etc., It is working fine.

    Hi Venkadesh,

    I have extended the forecast upto June 10th and run the scenario. The same result I got ie that requirements are getting clubbed.

    Hi Venkadesh,

    When calculating lot sizes and creating orders, the system considers all the other lot size settings from the location product master, such as minimum and maximum lot size, rounding value, and rounding profile

      Hi Senthil,

      Thanks for your quick response.But my question is it is generating PRs daily with weekly lot size if I use with safetyday's supply-10days and min.lotsize-50.My question can I use safety day's supply with periodic lot size or not?

      Thanks&Regards
