Service Loss Analysis for Substitute Products
If a customer-requested product was replaced at the first stockholding location by a one-to-one or a one-to-many substitution, service loss analysis does not only assign service loss reasons to the service loss quantity of the customer-requested product, but also to the service loss quantity of the substitute product(s).
Prerequisites
In Customizing for SAP Supply Chain Management (SAP SCM), you have defined the service loss reasons for which service loss analysis is to also check for service loss quantities of substitute products.

Features
If the successor product planning date has been reached by the service loss reference date/time , service loss analysis can check whether one of the following service loss reasons applies to the service loss quantity of the substitute products:
-
CautionService loss analysis can only assign this service loss reason if there is a final forecast for the successor product at the time of service loss analysis.
End of the caution.
NoteIf the successor product planning date has not been reached by the service loss reference date/time, service loss analysis can only check whether the service loss reason
Demand Exceeds Forecast
applies to the service loss quantity of the substitute product(s).End of the note. Scheduling agreement release and purchase order in limited freeze horizon
No scheduling agreement release or purchase order in limited freeze horizon
Restrictions
Service loss analysis cannot assign service loss reasons to service loss quantities that occurred for substitute products at the second stockholding location or at stockholding locations further down the bill of distribution (BOD).
Service loss analysis cannot assign service loss reasons for service loss quantities of kit components or substitution of kit components.
Activities
Service loss analysis assigns service loss reasons to the service loss quantity of the customer-requested product first. Only then does it assign service loss reasons to service loss quantities of substitute products. If the successor product planning date has already been reached when the
service loss reason Demand Exceeds Forecast
is assigned, service loss analysis only assigns service loss reasons to service loss quantities of the substitute product(s).
When assigning service loss reasons to service loss quantities of substitute products, service loss analysis calculates the throughput time on a product-specific basis.
If quantity factors exist in the interchangeability master data between the customer-requested product (predecessor product) and the substitute products (successor products), the system converts the assigned service loss quantity of a successor product into the equivalent quantity of the customer-requested product.
