How To Fix WT253 - Indicates that net change planning is to be used

WT253 - Overview

• Message type: E = Error

• Message class: WT - Retail: Replenishment

• Message number: 253

• Message text: Indicates that net change planning is to be used

&USE&
With the net change planning method, only those materials are included
in the planning of replenishments for which there have been changes
relevant to Replenishment since the last planning run. These change may
be, for example, stock changes or replenishment parameter changes.
Net change planning helps improve performance. If you do not use this
method, the planning run analyzes all materials for which Replenishment
is active.
&HINTS&
When the target stock is calculated dynamically, the net-change method
can lead to certain materials being "forgotten".
Example
You start net-change planning for a material where the target stock is
calculated dynamically and activate the net change method.
Due to an increase in forecast sales, the target stock (calculated
dynamically) is higher than in the last replenishment run.
Since no change relevant to replenishment has been made since the last
replenishment run, it is still not taken into account in Replenishment.
You should therefore only use the net change method for materials where
the target stock is calculated dynamically if you are sure that the
material has sold since the last replenishment run (i.e. there has been
a change in stock).
