DynaSys - Glossary

In the past : Demand history corrected (review past sales)

In the future : forecast calculated

It refers to the Firm Sales Requirements (ETA).

NB : In SILICA model, these volumes do not take into consideration the order book volumes if the option "Kill order book" has been flagged.

• Pull: the requirement is shipped as late as possible, that is during its requirement period
• Push: the requirement is shipped as soon as possible, that is during its production period
• Push beyond requirement: the requirement is shipped as soon as possible, including excess production

Usually is used in the customer view
Example:
Merchandise release in ETA:

• Actuals received in ETA: actuals received on this day (previously shipped from a shipping site)

Usually is used in the shipper view
Example:
Merchandise release in ETD:

• Actuals shipped in ETD = merchandise shipped on this day (supposed to arrive at the customer's later)

• Statistical forecast: theoretical forecast based on sales history + demand planners’ inputs,

• Customer forecast: from the customer himself
• Sales team forecast: commercials inputs, usually with the web access
• Final forecast: last validated Forecast [current month , futur]
• Invoice forecast: forecast billed

• Unconstrained forecast: forecast without any logistical / production constraints (comes out from DP)

• Constrained demand: new forecast after taking into account production constraints (comes out from DiP-PP)

• Forecast override: forecast priority onto another

Products shipped from a zone to another.
There are 2 types of intercos:

• Direct intercos: direct shipment to the client in another zone
• Indirect intercos: indirect shipments to the client in another zone (goes to a warehouse then to the client’s)

Represents the total time between placing a production / replenishment order and the availability date.  It’s “monolevel” since it only considers the product’s own lead times (scheduling / production lead time / ….) , does not consider other BOM level. It's independent of SHS (Stock Holding Strategy)

= need

Different types of requirement:

• Independent Requirement: flat requirement from firm orders
• Dependant Requirement: requirement from bill of material (ex: product A requires 2 of product B. We want to produce 2 x A → 2x2 product B = 4 dependant requirements)
• Sales Requirement: this is the direct requirement for sale to a customer. The sold item disappears from the inventory.
• Shipping Requirement: requirement to ship to another site. It is indirect because the sale will not be made on the site but rather downstream in the logistic network
• Gross Requirement: it is the sum of Independent Requirement and Dependent Requirement
• Net Requirement: it is achieved by Gross Requirements corrected by taking into account inventories (Initial inventory, safety stock variation, etc …)  This is the minimum theoretical quantity to be received to meeting the gross requirements
• Receipt Requirement: it complies with all the technical constraints

Customer / receiver

• Production sites: This is where production happens, or more generally stock inputs. It may correspond to a plant, a supplier, a warehouse, to which purchased items are delivered.
• Shipping sites: These are sites sending out items. Typically, they are plants, warehouses or intermediate distribution centers.
• Receiving sites: These are sites liable to receive items, like customer warehouses or distribution centers.
• Selling sites: These sites operate direct sale activity, i.e., locations where customer requirements are debited from the inventory

• Monosourcing: a site is supplied by one location

• Multisourcing: a site can be supplied by more location (ex: from St-Fons & Collonges)

Shippings met: packages delivered

Shippings met on time: packages delivered on time

Shippings met late: delay authorized for a delivery, once this delay is exceeded = shortage

Shippings not met: packages not delivered

In the past : Shipped history (departure date)
In the future : Order Book To Be Issued (Confirmed - ETD)

Stock Holding Strategy (MTO / MTS / MTF). Used specially in P&I module

Note: MTF are considered as SHS

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. It's a Multilevel LT and dependent on the Stock Holding Strategy (SHS).

Name of SAP Field which contains data for ATP check. Use always this term to avoid confusion and if possible avoid to use “TRLT” instead of “SAP TRLT” Represents the total time between placing a production / replenishment order and the availability date. In the context of P&I Project, it could stock the 'SHS RLT' calculated in DynaSys P&I module.
