> In order to calculate P&I 'Purchased LT' we take the sum of 'SAP Processing time for purchasing' + 'SAP Planned Delivery time' + 'GR processing time'

P&I Lead Times	Level Required	Proposed SAP Field	Purpose in SAP	SAP Level	Comment
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.	Could be maintained at different place: -Pld Delivery time from Purchase info Record (1st priority) - Pld Delivery time from MRP2 view (only if PIR is NA)	If both PIR + MRP2 view 'Pld Delivery time' are defined, we take PIR as 1st priority. 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.
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

Attention : the 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.

Note that in the determination of the Planned Delivery time, we have 2 sources: Purchase Info Record and MRP2 view. In DynaSys P&I, we follow MRP standard process: we take PIR Pld Delivery time as 1st priority. If it's not available, we take that from MRP2 view.

User can consult in SAP T-code ME01/ME02/ME03 or Table EORD, to see what are the different sources defined. For each source, then we need to consult tables EINE/EINA in SAP to get the Pld Delivery time.

Monolevel RLT Calculation

To calculate the total 'Monolevel' lead time of Purchased Materials, we add the Good Receipt Processing time ("GR processing time" of SAP MM > MRP2 view).

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).

Material / Plant

SAP Planned delivery time (Calendar days)

Number of calendar days needed to obtain the material or service if it is procured externally.

Could be maintained at different place:

-Pld Delivery time from Purchase info Record (1st priority)

- Pld Delivery time from MRP2 view (only if PIR is NA)

If both PIR + MRP2 view 'Pld Delivery time' are defined, we take PIR as 1st priority.

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.

GR Processing LT

Material / Plant

GR processing time (MARC-WEBAZ)

Number of workdays required after receiving the material for inspection and placement into storage.
