In the ACS, I don't see any filter options in the custom resources or profiles tables, the problem I see is sometimes it is wasting lot of time to find out records by date, email, etc...
The option which I see only is sorting which will not help much when we have huge data. I feel having filtering option will save time, when we want to do quick troubleshooting.
For custom resources. you can define the fields which shall be visible for filtering in the custom resources dialog
The same can be done for profiles though here only on custom fields which you added in your resource extension
I think the link which you provided talks about building the audience using query, but what I am looking some thing directly in the table instead of query.
We are sending leads from our website directly to the custom resource, when it comes to troubleshooting we can not go and build filter definitions and run workflow, sometimes we need to go and quickly check in the table.
Right, it was the wrong link.
Check the one above and search for "Advanced filtering"
