G. Supersessions

a. Definition- A part supersession is another way of saying ‘replaced by’. Supersessions differ from
Substitutions (which will be discussed next) in that they are issued by, and confined to, the specific
vendor. Supersessions are generally created when one, or several of the following conditions occur:
I. The current part has experienced a quality issue (high failure rate)
II. Additional parts may be necessary to perform a more
comprehensive repair
III. A component may no longer be available through normal
supply channels
IV. A cost reduction, or quality improvement can be obtained by sourcing through a different
supplier
Whatever the reason, the factory has determined that the original part, we’ll call it ‘Part A’, will
no longer be issued with all subsequent requests supplied with ‘Part B’. This is the definition of a
supersession.
b. Impact on Inventory- So that the flow of material is not interrupted, monthly sales history and
monthly HITS must be ‘moved’, or ‘superseded’ to the new part number. This ensures that future
purchases of ‘Part B’ are based on up-to-date sales history. Rotating the existing inventory of ‘Part A’
occurs at this stage when combined with the new stock of ‘Part B’ and placed ‘up front’ so it is sold
first. On some occasions, upon visual inspection of the new and old part numbers, it may not make
sense to move the existing inventory over to the new number. The Parts Manager and Inventory
Control Manager should be notified when this situation occurs so the appropriate Notes are added
to the ICS System
c. An example of a substitute part would be: Jenbacher product code 56 – 631265 is a
replacement for Jenbacher product code 46 – 631265.
F. Substitutions

a. Definition- A substitution (or ‘interchange’) is a part which will work in place of the original
manufacturers’ part and referred to as a ‘replacement’ part. This should NOT be
confused with the parts supersession definition of ‘replaced by’. Substitutes are supplied
by a ‘third party’ vendor who has determined the part to be comparable to, or in some
instances superior to the original vendors’ part.
b. Identification- Substitutes can be identified in the ICS System by selecting the ‘Substitute
Part’ button in the Actions panel of the Inventory Item Inquiry screen. Extreme caution
should be used when selecting Substitutes. Product Code selection becomes very
important at this stage as similar part numbers may not be ‘Substitutes’ for similar
products. There is a difference between ‘exact’ and ‘indirect’ substitutes. It is for this
reason that substitutes are generally researched and inputted by Corporate Parts.
c. Application- When selecting substitute parts, take the extra time to consult with the
Parts Manager, Assistant Parts Manager or lead parts team member available whenever
a Substitute part is being considered as an alternative for the Customer’s original
request. To ensure the highest level of Customer Satisfaction this should be the everyday
process for substituting merchandise - unless previous personal experience with the
substitute part has met the Customer’s expectation.
d. Exceptions- From time to time it is desirable to move sales history between parts of
different vendors within a branch. There can be several reasons for this. However, this
function is performed no different than a supersession with the exception that, once
completed, the supersession needs to be ‘unlinked’. Taking this additional step
(unlinking the supersession) prevents other branches from concluding the supersession
to be valid.
