How do I find all services that don't have a specific tag?

[Robert Campbell]

I am trying to filter services that don't have a specific tag. I have a list of ids but of those ids I want to see which don't have a tag "ABC"

I use a filter of CI ID is one of (100+). But because I have so many it creates a short url. If I do just 5 or so, I can see the url and add a '!' to the filter representing "Tag != ABC" but because there are so many, I cannot do that. Any suggestions?

Hi @Robert Campbell 

find all records that do NOT have a certain tag?

With the OOTB possibilities of the filters one does not come here further, however there is a trick.

	We start at the list of all Instance Scan checks with an empty filter and a result list of 621 records.
	The next step is the most important: You have to select two times the Tags criteria and combine them with an OR condition: one time with an empty value and one time with the Tag that should be excluded later.
	The result set is the same as before, and the filter breadcrumbs reflect the configured search. The next step is to reverse the search query.
	For that step examine the query part of the URL parameters (sysparm_query). The interesting part here is the double URL-encoded presentation of an equals sign: %253D Right before that expression, insert an exclamation mark which represents the negation of the following expression: ORsys_tags.a81628fc97266110b05bb08fe153afe4!%253Da81628f

If my response helped please mark it correct and close the thread so that it benefits future readers.

I have 1469 CI_IDs and the query is:
CI ID is one of ...

&&

Tag is not "In scope".

Because I have is one of, I'm not able to do the suggestion because it creates a tiny url.
