Parameter
Global settings and parameters are stored here.
Some of these parameters are used by the planning algorithm, others are used by the web application. Extension modules also add additional configuration parameters to this table.
Standard parameters
The table below shows the parameters that are recognized by the standard application.
Parameter |
Description |
|---|---|
allowsplits |
When set to true (default value), a sales order or forecast is
allowed to be planned in multiple manufacturing orders. An order of
eg 100 pieces can be planned with 2 manufacturing of 50 pieces.
When the parameter is set to false, this splitting is disabled. This
will result in a plan with less manufacturing orders. The plan
generation will be considerably faster, but can have additional
delivery delays of the customer orders and forecasts.
|
currentdate |
Current date of the plan, preferred format is YYYY-MM-DD HH:MM:SS
but most known formats to represent a date and/or time are accepted.
When the parameter is set to “today”, we use today 00:00 / midnight
as the currrent date.
When the parameter is set to “now”, we use the system time as current date.
If the parameter is missing, empty or has an uncognized format, the system
time is also used as current date.
|
currency |
Currency symbol.
This parameter may be only set on the default database and will be
globally applied, including in all the scenarios.
If the parameter is missing or empty the currency symbol will be the $.
By default the symbol will show after the value, i.e. 123 $.
For the symbol to show before the value a , should be added after the
symbol, i.e. $,, resulting in $ 123.
|
loading_time_units |
Time units to be used for the resource report.
Accepted values are: hours, days, weeks.
|
plan.administrativeLeadtime |
Specifies an administrative lead time in days.
FrePPLe will plan the sales orders this amount of time ahead of their
due date. This creates extra safety in the delivery schedule and also
moves all material and capacity needs early.
Default value: 0 days
Accepted values : Any positive decimal number.
|
plan.autoFenceOperations |
The number of days the solver should wait for a confirmed
replenishment before generating a proposed order.
Default: 999 (wait indefinitely)
Default before release 5.0.0: 0 (don’t wait)
|
plan.individualPoolResources |
Defines the behavior of aggregate resource.
A operation-resource record with quantity N for an aggregate resource
can mean either:
- Find a member resource with size N. Value false, default.
- Find N member resources of size 1. Value true.
|
plan.calendar |
Name of a calendar to align the end date of new manufacturing orders,
purchase orders, distribution orders and delivery orders with.
When this parameter is used, the plan results are effectively grouped
in the time buckets defined in this calendar.
This feature is typically used for medium and long term plans.
Such plans are reviewed in monthly or weekly buckets rather than at
individual dates.
|
plan.loglevel |
Controls the verbosity of the planning log file.
Accepted values are 0 (silent – default), 1 (minimal) and 2 (verbose).
|
plan.minimumdelay |
Specifies a minimum delay the algorithm applies when the requested
date isn’t feasible.
The default value is 3600. This value should only be changed when the
planning run is taking a long time and the log file shows that demands
take many iterations to be planned - where the requested delivery
date for each iteration is advancing only in tiny increments.
|
plan.planSafetyStockFirst |
Controls whether safety stock is planned before or after the demand.
Accepted values are false (default) and true.
|
plan.rotateResources |
When set to true, the algorithm will better distribute
the demand across alternate suboperations instead of using
the preferred operation.
|
plan.webservice |
Specifies whether we keep the plan in memory as a web service for
quick incremental planning. This functionality is only available in
the Enterprise and Cloud Editions.
Accepted values are false and true (default).
|
COMPLETED.consume_material |
Determines whether completed manufacturing orders consume material
or not.
Default is true.
|
COMPLETED.allow_future |
We assume that completed operations are always ending in the past.
The planning engine will automatically adjust the end date to enforce
this rule, unless this parameter is set to true.
Default is false.
|
WIP.consume_material |
Determines whether confirmed manufacturing orders consume material
or not.
Default is true.
|
WIP.consume_capacity |
Determines whether confirmed manufacturing orders, purchase orders
and distribution orders consume capacity or not.
Default is true.
|
WIP.produce_full_quantity |
Controls how material is produced from partially completed
manufacturing orders.
When set to “false” (the default) a partially completed manufacturing
order is producing only the remaining quantity of material. We assume
that the on hand inventory has already been incremented to reflect
the produced material.
When set to “true” a partially completed manufacturing ordre will
still produce the full quantity of the material. We assume that the
produced material will only be booked as inventory when the
manufacturing order is fully finished.
