We are currently using PPM 15.3 SaaS. We are wanting to export the task list via the scheduler to MS Project 2016 in edit mode. We have installed the 15.3 scheduler add-in from CA. However, the file opens with the VBA debugger error as follows: "Ambigious name detected: CA_VBA_IS_CUSTOMIZED". Any ideas on what this means?
