To easily identify were are you maintaining buffers in your Bill of
|
|
Materials, you will need to first provide location information on the Bills
|
|
of Materials.
|
|
|
|
* Go to *Manufacturing / Products / Bill of Materials* and update the
|
|
'Location' in all the Bill of Materials and associated lines,
|
|
indicating where will the parts be placed/used during the manufacturing
|
|
process.
|
|
|
|
* Print the report 'BOM Structure' to display where in your BOM are you
|
|
maintaining buffers, and to identify the Lead Time (LT) of each product, and
|
|
Decouple Lead Time (DLT).
|
|
|
|

|
Buffers
|
|
~~~~~~~
|
|
|
|
To list the list of inventory buffers, go to one of the following:
|
|
* *Inventory / Master Data / Stock Buffer Planning*
|
|
* *Inventory / Master Data / Reordering Rules*
|
|
|
|
|
|
Buffer Profiles
|
|
~~~~~~~~~~~~~~~
|
|
Buffer profiles make maintenance of buffers easier by grouping them in
|
|
profiles. Changes applied to the profiles will be applicable in the
|
|
associated buffer calculations.
|
|
|
|
* Go to *Inventory / Configuration / Buffer Profiles*.
|
|
|
|
The Buffer Profile Lead Time Factor influences the size of the Buffer Green
|
|
zone. Items with longer lead times will usually have smaller green zones, which
|
|
will translate in more frequent supply order generation.
|
|
|
|
* Go to *Inventory / Configuration / Buffer Profile Lead Time Factor* to
|
|
chan
|
|
|
|
The Buffer Profile Variability Factor influences the size of the Buffer Red
|
|
Safety zone. Items with longer lead times will usually have smaller green
|
|
zones, which will translate in more frequent supply order generation.
|
|
|
|
* Go to *Inventory / Configuration / Buffer Profile Lead Time Factor*.
|
|
|
|
Usual factors should range from 0.2 (long lead time) to 0.8 (short lead time).
|
|
|
|
|
|
Product attributes
|
|
~~~~~~~~~~~~~~~~~~
|
|
|
|
* For manufactured products, go to *Manufacturing / Products* and
|
|
update the 'Manufacturing Lead Time' field, available in the tab *Inventory*.
|
|
* For purchased products, go to go to *Purchasing / Products* and update the
|
|
*Delivery Lead Time* for each vendor, available in tab *Purchase* and section
|
|
*Vendors*.
|

ADU Calculation Methods
|
|
~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The Average Daily Usage (ADU) defines the frequency of demand of a product in a
|
|
certain location. It can be computed in different ways, which you can configure
|
|
with ADU calculation methods as follows:
|
|
|
|
#. Go to *Inventory / Configuration / DDMRP / ADU calculation methods*.
|
|
#. Indicate a name, a calculation method (fixed, past-looking,
|
|
future-looking or blended).
|
|
#. Fill the corresponding period (past, future or both for blended method) to
|
|
specify the length of period consideration (in days).
|
|
#. Indicate the source of information: stock moves or demand estimates.
|
|
#. If you use the blended method fill also the *Past Factor* and
|
|
*Future Factor*.
|
|
|
|
If you do not have prior history of stock moves in your system, it is advised
|
|
to use fixed method or start to work on future estimates. If you have
|
|
past-history of stock moves, best use past-looking method or blended method.
|
|
|
|
The ADU is computed every day by default in a background job independently
|
|
from the other buffer fields. This computation can be done with less frequency
|
|
but it is not recommended to run it less than weekly or more than daily.
|
|
Circumstantially, If you need to force the calculation of the ADU go to
|
|
*Inventory / Configuration / DDMRP / Run DDMRP* and click on
|
|
*Run ADU calculation*.
