Hi Ramu,
First, there are several types of inventory journals:
Movement,Inventory adjustment,Transfer,BOM,Item arrival,Production input,Counting,Tag counting.
What you create in Inventory management > Setup >Journal names >Inventory journal names is the journal name, if you want to create a movement journal, you need to click New in Inventory management >Journal entries>Item>Movement, as shown in the screenshot below. When you are finished creating, it will be visible in the view. Hoping that can help you.



Best Regards
