2. Lead times coming from SAP

> Synthesis of P&I Leadtimes extracted from SAP

P&I Lead Times	Level Required	Proposed SAP Field	Purpose in SAP	SAP Level	Comment
Catalog LT	Material / Plant	Dedicated new field	Catalog Lead Time from “Order Entry Date” until “Material Availability date	Material / Plant Working days	See dedicated section here Besides P&I, also used in CEM control : Order Date - Material Availability Date >= Catalog Lead Time (Taking into account the SAP plant calendar)
Plant Replenishment LT	Material / Plant	Total Replenishment Lead Time (TRLT). In SAP technical name is MARC-MZEIT	TRLT is used: > definition of TRLT horizon in MD04 (Planning) > Sales order confirmation ((only if the ATP key is set to consider the TRLT): if no availability found at the requested date, the availability date in sales order is automatically confirmed at today + TRLT. Usually activated for MTO products.	Material / Plant Workdays	Proposal : this SAP field will contain the SHS RLT calculated in the P&I DynaSys solution.
Production LT	Material / Plant	Work scheduling view : Processing time (MARC-BEARZ) + Base quantity (MARC-BASMG) or if not filled-in MRP view or Work scheduling view : Inhouse production time (MARC-DZEIT)	The Processing time from 'Work scheduling view' is used by the MRP -> Scheduling activities. The 'Inhouse production time' in MRP view is not used by MRP, it's just an information of lead time needed for production.	Material / Plant Workdays	See dedicated section here
Procurement LT	Material / Plant	SAP Processing time for purchasing (Workdays)	Time (Plant workdays) that the purchasing department requires to convert a purchase requisition into a purchase order.	Plant x workdays Define at Plant SAP Custo (an example of value could be 2 days).
Procurement LT	Material / Plant	SAP Planned delivery time (Calendar days)	Number of calendar days needed to obtain the material or service if it is procured externally. It's used by the MRP are used to manage the flows between plants and warehouses. For the ordering plant, this information is helpful to send the information to the supplying plant on time. Attention: It should only consider the 'transit time' between sites, it shouldn't include the Production lead time at supplying plant.	Material / Plant Calendar days Could be maintained at different place: - Purchase info Record - MRP2 view	Attention : this Pld Delivery time (both in MRP2 view or PIR) should only consider transit time => the transit time will be used to back calculate the correct Production & Good issue date in shipping site on SAP. See dedicated section here
GR Processing LT	Material / Plant	GR processing time (MARC-WEBAZ)	Number of workdays required after receiving the material for inspection and placement into storage.	Material / Plant Workdays
Administrative Scheduling LT	Material / Plant	No SAP equivalent	-	Material / Plant Workdays	No field in SAP available. Will be manually defined in DynaSys, more info in detailed section here.

> P&I methodology Lead times (Macro view)

> SAP Lead times summary (detailed view)

P&I solution takes the Lead times coming from SAP until the Material Availability Date.

All that happens afterward (Loading + Pick Pack + Transit time to customer), in gray below, is not part of DynaSys P&I scope and is carried outside the tool.

> SAP Lead times transferred to P&I

Key information to be taken into account:

Production Scheduling: No information in SAP related to the Scheduling LT -> Will be defined in the P&I solution.

It's considered in SHS RLT calculation but not like an 'addition'. More information in 'Scheduling LT' part.

Inter/Intra Company Scheduling:

Planning time fence at receiving plant to be consistent with stockholding strategy and replenishment LT
