Most Recently Used
You can use the most recently used (MRU) feature in most fields that are equipped with a lookup. Click in a field with a lookup to view your five most recently used (MRU) values for that field.
MRU is applicable from function to function. For example, if you specify a product in Inventory Movement and then create an issue, the Inventory Movement product is an MRU value in the Product field on the issue.
