Planning Flexibility: firming vs. fixing supplies

Planning Flexibility ... very frequently, users expect this flag as a tool to firm supplies. However, the right way to define what is this flag for is as a tool to Fix supplies but not to firm supplies. How is this flag used in the planning engine?

Just to start with, Planning routine in Dynamics NAV actually performs two actions:
- checks inventory availability
- then, based on the inventory availability, it suggests action messages with proposed changes on the inventory profile.

In the other hand, Planning Flexibility is a flag, which is available on production and purchase orders, with two permissible values: Unlimited and None.

When Planning Flexibility is set to Unlimited means supply (purchase, production) will be use during the planning routine in both inventory availability calculation and the action message proposals. Therefore, planning could request a quantity or due date change of this supply with flag set to Unlimited.

However, if Planning Flexibility is set to None, change proposals (action messages from second step in planning) will ignore any supply (purchase, production) with this flag set to None. This means, supply will be used to calculate inventory availability but will not be considered to propose changes (date, quantity changes) since it is considered as a fixed supply.

SCM related with NAV? Why for?

Or better ... why not?
I just got a word with one of my friends at work (thanks Luis :-) ) and he suggested this would be a nice way to share Dynamics NAV SCM knowledge with other people out there.

I am dealing with Dynamics NAV on my daily work: bugs, design questions on how is Dynamics NAV suppoused to work, ... But besides dealing with Dynamics NAV ... I am an SCM evangelist, dreamer, believer ... Yes, I have been working with SCM tools for the last 10 years from both ERP and/or MRP II functional perspective.

Having this in mind, I would be adding content to this blog of all those nice questions, tips, tricks or functional comments related with SCM which would good to share. Final goal would be to use this blog to compile all those tips and tricks and use it as a reference.

Just to ensure we all readers of this blog have common understanding, SCM is considered to be all those business processes related with:
- Sales & Purchase Profit (sales and purchase order management)
- Inventory Optimization (planning, inventory management)
- Warehouse Management
- Cost Reduction (Cost method and application)
- Service Management
