Wildcards are special characters you can substitute for other characters. Using wildcards allows you to search for items that contain a particular set of characters.
You can use different combinations of wildcards to search, e.g. ?OU* will search for values with three or more characters which have OU as the second and third characters.
If you enter a value in both boxes, both must be found for the stock item for the item to be displayed in the list.
For example, if you enter ?OU* in the Stock Code box and *Aluminium* in the Name box, stock codes are only displayed where the Stock Code has OU as the second and third characters of the code and the word Aluminium is used in the Name.
