add new items, but no inventory in item type pull-down menu

Question:

I have premium manufacturing & wholesale distribution, 2012. I set my
company under wholesale, distribution. When I try to add new items item type pull down menu does show any “Inventory item”. It only has service,
non-inventory etc. I don’t know why. I have any company set up same, under
wholesale & distribution. But it has item type: “inventory” so that I can
add inventory items. Please help me. Thanks in advance.

Answer:

GO to Edit menu > Preferences > Select Items & Inventory > Select Company Preferences > Check mark Purchase Orders & Inventory > Click OK
