Hi Deb!
I am actually working on a project as we speak where we are removing WMS and changing the costing methodology from standard to weighted, so very close to your request! I would like to provide a fair warning that this solution may not be the most creative, but here is where I am currently at..
The happy path would be to create all new items and start fresh. Depending on your data and how many years your organization has been on Dynamics, this may actually be the most time-efficient route to take. If not, proceed below!
In order to change the item model group on existing items, you'll need to have ALL transactions for that item financially closed. Ensure you have the following done:
- All production orders ended
- All pending inventory transactions posted or deleted
- All purchase orders that have been received for these items need to be fully invoiced
- Any sales order where these items are on need to be fully invoiced
- I recommend deleting any pending inventitemprice records too for these items
Once you have finalized the transactions, you'll want to go to the Inventory management > Inquiry > Transactions grid and re-confirm all records show a date populated in the financial date field. If everything is dandy, count out the inventory via counting/movement/adjustment journal, run a recalculation/month-end close job, then go to the released products and change the item model group.
Now, if you get this error message:
'The item is set to be evaluated by inventory model "Standard cost". The system cannot convert the item to be evaluated by an inventory model of type "Transactions settled" only inventory models of type "Transactions not settled ...."
You'll need to get with a developer to temporarily remove that logic check in order to proceed. Again, not the most advised route to take, but it'll get the job done. Creating new items entirely may be the route to go if you want to avoid all of the outlined items.
Once you're on FIFO pricing, I'd recommend some of the following
- Run a recalculation often, most of my clients opt-in to do this nightly
- Review the production control parameters and enable the 'use estimated cost price' and 'price calculation' flags
- Create a costing version for planned costs and create a pricing fallback for your FIFO items
Let me know if this helps.

Subject: Change inventory cost method from standard to FIFO
We want to change the current inventory costing method from standard to FIFO for some in stock items. How can we accomplish this since there are transactions against these items?
