> The Production LT will be calculated only for Materials that are Produced. We will use SAP "Procurement Type = E" (In House Production) to identify those Materials.

> In order to calculate P&I 'Production LT'we take as default the 'Processing time' from Work scheduling view (SAP Material Master). If this value is empty, we take the 'Inhouse production time'.

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" from MRP2 view is not used by the MRP.

Material / Plant

Workdays


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

Monolevel RLT Calculation


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


Monolevel RLT Purchased Materials = Production LT + GR Processing LT


SHS RLT Calculation


The SHS-dependent Replenishment Lead time (SHS RLT) will be calculated from a number of different lead times coming from SAP.


> This SHS RLT will be multilevel & multi-site 

> We will compare this ‘Industrial’ RLT with the Promised LT to Customer (‘Catalog LT’) and adjust the Strategy of the Product (MTO, MTS, MTF) accordingly.
