no items show up when I try to calculate item demand plans. How do I fix this?

AI generated answer (using internal Slack threads):

If no items show up when you try to calculate item demand plans, there could be several reasons for this. Here are some potential solutions based on the conversations: 1. Check the Vendor field: In one of the conversations, it was mentioned that the issue was resolved by checking the Vendor field. Make sure that the items you are trying to generate demand plans for have the correct Vendor field set up. 2. Check the Time Fence: Another conversation mentioned that the issue was resolved by clearing the Time Fence in the inventory management preferences. If the Time Fence is set to a large number of days, it might prevent the system from generating demand plans for items that are out of stock. 3. Check the Cost Accounting Status: If the issue is related to cost calculations, you can create an item saved search with "Cost Accounting Status" criteria equals to "running" or any other negative sounding status. This will help you identify any items that might be causing issues. Remember to always double-check your item setup and inventory management preferences when you encounter issues with demand planning. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
