Production forecasts

Hi
I have a customer who makes his own manual production forecast for periods of 21 working days each (cyclic planning). They want to use NAV Production forecast to create all the production orders within a certain period.
The problem is that when they insert their numbers in production forecast sheet the system calculates with the current amount and current production orders already in the system.
Is it possible to force NAV to ignore the current amount of orders and storage and just create production orders for the specified amount?
If it's not possible by some GUI flag, is it easy to programmatically achieve such a functionality? It should of course take the current amount of orders and storage for the components, but not for the sales products.
Or is there another way to do it since they will continue to do their own forecast with some human sence involved (hard to program such).

we've enocuntered same problems in planning.
Some companies just want to do gross planning
(just simple plan for forecasted quantities).
And solution is not quite difficult:
Regenerative plan is called from report:
R99001017 Calculate Plan - Plan. Wksh.
Here you can add some exclusions and parameters on Options tab,
who can be used and passed to:
CU99000854 Inventory Profile Offsetting¸
This Codeunit is driving planning engine.
There are two key triggers:
Function DemandtoInvProfile()
here you can exclude Demands, like
Sales, or Consumption for Prod.orders
Function SupplytoInvProfile()
here you can exclude supplies, like
Purchase, or Output for Prod.orders for example.
Is it possible with your suggestion to be able to just ignore exsting orders and storage for the sales items and still have the check unmodified for the components needed to produce the sales items?
Maybe a silly question, I guess you already have answered it, but since I haven't been able to look in the code I found it easier to ask.
When I add some forecasts by the date april 23rd and then run the production planner to create the necessary orders and purchases I get some strange beviour as I think.
Some of the production suggestions starts some time before 23rd. I take that as NAV sees the given date as the date when the production should be finished. But then I see that some of the actions has an ending date after 23rd too. ](*,)
How is the planner thinking? If I want to plan a bunch of production orders in a certain week, how can I make the planner to begin production on monday and fill out the week with the planned orders? :roll:
these are questions hard to answer without seeing
your customer data.
And even then...it's REALLY big pain in the ass, how to check
what system calculates in planning engine.
In general...you get the data after 23rd. Because system
looks ALL data, it may be caused by many sources. In general,
these possible sources are:
DEMAND (-)
- Sales Orders
- Production forecasts
- Production Order Components
- Outbound Transfer Orders
- Reorder Point (on Item Card or SKU)
- Safety Stock (on Item Card or SKU)
- Negative Item Journal Lines (something not posted yet !)
- Negative Item Ledger Entries
SUPPLY (+)
- Purchase Orders
- Production Order Lines (Output)
- Inbound Transf.Orders
- Positive Item Journal Lines
- Positive Item Ledger Entries
An even then, when you check all that...
you must check, what have you set-up on:
- Item cards (Parameters for planning are mostly held
on Replenishment tab).
- if you have Stockkeeping units, check that too
- Manufacturing Setup , tab Planning
Tip: it's VERY helpful, when you have all flow-fields, affecting
Demand and Supply on Item Card or/and Item List.
Mostly they are alrealdy in Table 27.
No.
And just one word...
WHY ? :roll:
If you don't need some items...why do you need components ?
