3751386 - IBP: Recommended Safety Stock changes occur in periods where min and/or max SS constraints do not exist

• Multi-stage Inventory Optimization (MSIO) is run without any min/max SS constraints and Recommended Safety Stock (RSS) is calculated.
• Then min/max SS constraints are set, using I_MINSAFETYSTOCK and I_MAXSAFETYSTOCK (SAPIBP2) or IOMINSAFETYSTOCK and IOMAXSAFETYSTOCK (SAPIBP1), and MSIO is run again.
• The result is that RSS changes occur in periods other than where the original RSS exceeded the maximum safety stock constraint in the first place, which is unexpected.
  • That is to say, key figure I_DELTAMINMAXSAFETYSTOCK (SAPIBP2) or SAFETYSTOCKMINMAXDELTA are <> 0 in periods where it is unexpected.
• The original unconstrained SS exceeded the I_MAXSAFETYSTOCK/IOMAXSAFETYSTOCK in only a couple of periods in the optimization horizon.
