I am receiving a "QE-DEF-0186 General Error" error anytime I attempt to add a security filter to my data layer query subjects. I have performed this action in the past on a model without issues, but now I am unable to add the security filter without receiving this error. I have checked the log files and they are not much help and I have even go as far as opening a case with Cognos Support and unfortunately I haven't received much help there either. Has anyone ever seen this happen? Is there something that I'm missing? Thank you in advance for your assistance!
