Cartegraph filters do not allow multiple lookups to the same field more than once.
To filter the Work Orders list to only those with an Owner whose Supervisor’s First Name is John, you would try to run this filter on the Work Order Advanced Filter dialog box:
Owner\Supervisor\First Name Is John
Since the Work Orders\Owner and Labor\Supervisor fields have the same lookup source of the Labor recordset and the Cartegraph Administrator application filter does not allow going through the same lookup source more than once, the following error display when you click Activate:
"Filter contains an invalid value. Correct the errors to continue.”
This filter is not allowed, change the filter to continue.
