Just coped SAP3 std model with advanced copy with Prefix of NKE and named as PA= “NIKEINVO” on SAP on Demand cloud server. configured inventory model and upload data successfully and only the safety stock calculation are not upto the mark/expectation
Single Stage:
Issue: Irrespective of defined Service lvl in excel or loaded service lvl, it always calculates with 99.99% service lvl in single stage optimization
PFA: SingleStageopt_ output.xls
Multi stage:
Run 3 tests to conclude
1) with time varying target stock and forecast, forecast error CV constant across
2) with time varying Target stock , Forecast error CV and Forecast constant across
3) with time varying Target stock , Forecast error CV and Forecast
Issues :
1) Always calculates Service Variability Safety Stock but not computing Demand variable safety stock ( even inputs maintained Forecast & Forecast error CV)
2) Recommended safety stock range should be 41-60 range ( more safety stock at customer facing DC ) and Plants should be ranges of (10-18) but behavior is completely different
3) Internal Service lvl (Non-stock out) data maintained in MD as in the range of ( 0.5 to 0.9) and always picks up 0.5 across, not at all computing, why no change
4)) Propagated Std deviation based on first bucket Forecast error CV and the same value of first bucket being used across time buckets ( No variability with input values)

Would you suggest how to overcome these issues
