a. Review RM & Int Inputs

Proposed SHS

The Proposed Stock Holding Strategy (SHS) represents the output of the Decision tree in DynaSys by considering all the different criteria (see "Decision tree for RN & Intermediates definition" above).

This Proposed SHS will be used into calculating the "Cycle Stock proposed", "Safety Stock proposed" and "Target stock proposed", and compare them to the existing current Cycle, Safety and Target stock.

Example values : for Raw Materials, possible values are PTO and PTS. For intermediates, possible values are MTO, MTO-FB and MTS.

Reason

It gives the reason of the proposed SHS, to guide the user as to why the SHS is proposed. It represents the different decision nodes of the Decision tree.

Example: for Proposed SHS = PTS, a reason code could be "Storage Y ; High Order Frequency ; RLT>FG scheduling LT". . Another example, now for Proposed SHS = PTO, it's the reason = "Storage Y ; Low Order Frequency".

Existing storage for RM

This has to be manually input by user, by default it's equal to TRUE (i.e., a storage for RM exists). If no storage exists, it can be easily untick by user.

Possible values: True (Storage exists) / False (no storage exists).

For the Raw Materials & Intermediates it represents the Historical Demand (consumption + demand to other Solvay sites). It's calculated in DynaSys based on last 12 months demand, and represents Number of weeks with Demand / Number of weeks in the year.

The Demand includes both Independent demand (to other Solvay sites) + Dependent demand (internal consumption/use inside a site).

SHS RLT

It's calculated in DynaSys and represents the Strategy-dependent Replenishment Lead time. 

Represents the total time between placing a production / replenishment order and the availability date. It considers other BOM levels lead times (multi level) + distribution network (multi sites) and stock holding strategies.

Shortest FG SLT

The "Shortest FG SLT"  is calculated in DynaSys and represents the lowest Administrative Scheduling LT of the Parent products (n+1 level in the BOM). It can be thought sort of a "Catalog LT" for Components.

> It's important to note that here we are talking about the administrative Scheduling LT (related to but not exactly equal to the notion of 'Scheduling LT' in SAP). More info here: Scheduling LT.

> By default, all the Intermediates & Finish Good have a "Scheduling LT" of 3, but it can be forced to a different value inside DynaSys.

It's calculated in DynaSys. A Raw Material/Intermediate is critical if one of the following conditions is fulfilled:

> It has only one vendor (Supplier). The 'Number of vendors' is calculated from SAP Purchasing Source list. For more info, please consult functional section Purchased LT

> It's used in more than 5 Parents. This information is known thanks to the BOM of SAP.

It's calculated in DynaSys and represents the Economic Order Quantity (EOQ), i.e., the optimal quantity to buy in order to minimize the total costs of inventory

It will be compared to the the Min 

Used for Raw Material, this notion comes from SAP (Purchase Info record) and is determined by the supplier. If the EOQ is smaller than the min order quantity stock will need to be held to ensure enough supply

Used for Raw Material, this notion comes from SAP (Purchase Info record) and is determined by the supplier. if the EOQ exceeds the max order quantity, stocks will have to be held to ensure enough stocks available.

It comes from SAP and is the same used in DiP screens. More info in Distribution multiple priorities page.
