Hi,
Not sure if I should post it here or in the FI / CO forum, but here it is ...
I'm in the process of implementing APO in a Aerospace company in Montréal, Canada and we're stuck on an Account Assignment Planning, and Product Costing issue.
Today, all demand / production / movements / costing is done by creating a Project Network.
Here are the current settings:
- Create a project with activities for each major "line section" for major components.
- Each activity has a component allocated to it
- Each activity has a different WBS element assigned to it.
- All production orders/purchase orders/goods movements are created/posted against the WBS elements.
- All stock for MTO parts are assigned to the WBS element
In order to provide better integration with APO and bring more flexibility in the Planning and Simulation processes, we were hoping to stop using Project Networks as the trigger for demand / planning / execution. The idea was to use Sales Orders (or Customer Independent Requirements - CIR) to generate the demand and run APO and MRP planning from it. The special stock segment now becomes linked to the sales order (or CIR) which changes alot of thing in the accounting documents and costs elements in the whole planning and execution processes.
Here is what we were hoping to achieve in order to limit impacts on finance :
- we are implementing APO and would like planning to be performed without using project networks.
- we would like to have planned orders for the top level for long term and be able to trigger the purchasing of long lead time items.
- we would like all goods movements (PO reception, GI to production order etc, ) to be posted to WBS elements
- we would like all production orders to settle to WBS elements
We tried different scenarios with different account assignments categories, but could not find one that fits the bill :
1) we tried using account assignment category "D" which allows assignment to sales order and WBS element. We created CIR as demand.
The problem is the stock is non-valuated which resulted in having no accounting documents for goods issue to production order.
2) we tried account assignment category "Q" with using CIR as demand. We had one WBS element assignment in the CIR. When we changed the WBS value in planned orders to represent each "line section" we ended up with duplicate demand in the original segment and the new segment.
So, is there a scenario with valuated stock that would allow us to do a make-to-order process that would post all costs to WBS?
Thanks,
Marc
