Depending on your requirement, use * wildcard character or not (or perhaps ? wildcard character).
- Click on the green + button to open the "Find Affected Objects" screen.
- Enter a string in the Number field that includes the part numbers separated by a semi-colon (;).
- For example: ITEM1*;ITEM2*;ITEM3.
- FYI...I think the character limit for this type of thing is 1000 characters. So watch out or it will get truncated and you won't get all 2000 objects.
