Simple Discontinuation of Products In Capable-to-Match planning (CTM), you can plan the simple discontinuation of a product . With simple discontinuation, a product is only valid until a certain date – the discontinuation date. After the discontinuation date, the successor product is valid. To fulfill product demands that lie after the discontinuation date, CTM must procure the successor product. If it allows the use-up strategy, CTM can also use the excess supplies and receipts of the product, to fulfill product demands after the discontinuation date. However, CTM cannot use excess products to fulfill demands for the successor product.
Note
As CTM plans an individual demand for the entire BOM, CTM cannot guarantee that product supplies are used up completely. This is particularly important when you plan a product with a fixed lot size.
CTM uses product interchangeability in all planning segments except the forecast segment. In the subcontracting scenario, CTM does not use product interchangeability.
You have created a product interchangeability group with a supersession chain and assigned the product interchangeability group to the supply chain model that you have also specified in the CTM profile.
The following conditions apply to the supersession chain and the products in the supersession chain.
The supersession chain may not contain any assemblies.
A product can only be contained in one supersession chain.
The base unit of measure must be the same for all products in a supersession chain.
A supersession chain may not contain any configurable products.
You have assigned the supersession chain to the locations at which you want to plan substitutions.
You have set the
Use Discontinuation
option in the CTM planning profile under
Strategies
on the
Special Strategies
tab page in the
Product Interchangeability
field
.
CTM supports linear supersession chains with products that are linked by substitution relationships of type
Interchangeable Forwards
. If two products are linked with a substitution relationship of type
Completely Interchangeable
, CTM processes the products as if they are only interchangeable forwards .
CTM evaluates the following entries that you made in the supersession chain:
Product
Successor product
Valid-from date
Use-up strategy
Use-up date
CTM displays the three use-up strategies of the supersession chain with two substitution strategies:
Use-up strategy
Unrestricted use-up time is possible
corresponds with the substitution strategy 1
Use-up strategy
Use-up is not allowed
corresponds with substitution strategy 2.
CTM represents the use-up strategy
Use-up until use-up date possible
with substitution strategy 1
and
substitution strategy 2. You can recognize this from the overview of the CTM master data check, that two entries appear for one location product. One entry uses substitution strategy 1 and specifies the time period in which using-up is allowed. The other entry uses substitution strategy 2 and specifies the time period after the use-up date in which using-up is no longer allowed.
When CTM uses product interchangeability, the system executes the search for receipts and supplies in the scheduling direction determined in the CTM profile. The result of the search also depends on the demand date and substitution strategy. (Subsequently, “validity period” is used as an abbreviation for “validity period of the corresponding substitution strategy”.)
Backward scheduling and demand date within the validity period
The system executes the search within the validity period. The search only then takes place before the validity period with substitution strategy 1.
Backward scheduling and demand date before the validity period
The system executes the search before the validity period. If a primary demand is concerned and late demand fulfillment is allowed, the search will take place within the validity period, if necessary.
Forward scheduling and demand date within the validity period
The search only takes place before the validity period with substitution strategy 1, and then within the validity period. The system executes the search within the validity period with substitution strategy 2.
Forward scheduling and demand date before the validity period
The search is executed before the validity period. If a primary demand is concerned and late demand fulfillment is allowed, the system executes another search within the validity period, if necessary.
The system can only create a new receipt element within the validity period as a receipt from a product substitution order, while taking the use-up strategy into account.
To represent substituting a product with the successor product, CTM creates a product substitution order. CTM considers here the safety days’ supply for the product. For the corresponding dependent demand of the successor product, CTM does not schedule a safety days’ supply. The dependent demand of the successor product uses the maximum earliness value from the discontinuation product.
In the CTM planning order selection, the usual selection criteria are valid for substitution orders. CTM planning does not delete substitution orders that the system creates within the production horizon.
If you are working with an SAP R/3 System in an integrated scenario, you must not enter in the supersession chains location products for which dependent demands can be created from stock transfers.
The ATP check does not adjust the substitution orders. If the substitution orders lie in the production horizon, CTM planning does not delete them. In a planning scenario with ATP check, a PP/DS planning run must ensure that the system deletes these substitution orders (see Adjusting Product Substitution Orders no Longer Required ).
