> 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) | Specifies the time needed to process the material in the operations at the different work centers. The processing time depends on the base quantity (Batch size) | Material master data - Work Scheduling 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. |
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: - Purchase info Record (1st priority) - MRP2 view (only if PIR is NA) | If both PIR + MRP2 view 'Pld Delivery time' are defined, we take PIR as 1st priority. | |
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.

> The PIR Planned Delivery time will be used to determine the “Procurement LT for P&I” (cf. previous slide).
> There is an interface between SAP -> BW -> DynaSys, with the following rules:
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).
