Simulate Multilevel Material Availability
Explanation
Use this activity to check the availability of a part and its components
based on a specific need date and quantity. Only plannable and buildable revisions
and only manufacturing and purchase structure types can be selected for this
simulation. The data can be sorted by Revision No in descending
order.
To perform this activity, configure below options in the Simulate
Options section, then click Simulate Material Availability:
- Need Date - The date on which the part quantity is
required to be available in inventory.
- Quantity - Part quantity for which the availability
check is performed.
- Project / Activity Seq No - The
project / activity for which the availability check is performed.
Netting of the top part and the non-standard planned components will be
as follows:
- If a Project is entered and there is no value
entered in Activity Seq No field, parts will be
netted from the project inventory.
- If both Project and the Activity Seq No
fields are null, parts will be netted from standard
inventory. If “#" is entered , parts will be netted from standard
inventory and project inventory of all the projects.
- Note: Standard planned components and their
child parts are netted from standard inventory.
- Skip Top Level Netting - Enable this option to
ignore the on-hand quantity of the top level part. I.e., component
availability check would be performed for the total quantity in the
Quantity field.
- All Levels - Enable this option to calculate and view the availability
for all levels of the product structure (BOM). If components have
sufficient on-hand and open supply to cover demand then the netting
explosion is stopped. Unaffected components are removed.
Once the calculation completed, the list will show the availability of
each part in the structure. The Availability Message field helps in determining whether
or not to create new supplies for the given part. The messages and the respective
indications are as follows:
- Available covers Demand: there is no need to create new supply.
- Available
+ Open Supply covers Demand: there is no need to create new supply.
- Need
Orders: there is a need to create new supply. However the calculated start date
of this supply will be later than or equal to today (i.e., the system date).
- Min Simulated Start Date earlier than Today: there is a need to create new supply.
The calculated start date of this supply will be earlier than today (i.e., the
system date).
- Not Calculated, Parent Qty OK: the components have not been
netted because there is sufficient parent quantity available. This message is
only displayed if the Show All Levels option is enabled.
Select Show Shortages Only to display only the parts for which there is a material shortage, i.e. components for which
the projected quantity on hand on the required date is less than zero.
Prerequisites
- An inventory part must be defined and must have a buildable structure.
- Material lines that are customer owned, or not consumed will not be
considered.
System Effects
The system calculates the availability of the selected part under user-specified
simulated conditions.
