Good news - It fixed itself over the weekend.
Bad news - It fixed itself over the weekend and I don't know why.
I ran 'Create & Update Jaspersoft Users' before I posted this, but when this didn't fix it I thought it best to stop guessing late in my day on a Friday and post up my Q.
Do you think any of the Data Warehouse jobs could affect this? Load Data Warehouse Access Rights? We run this nightly.
I'm pushing to Test today. I'll see if I can isolate this & post the work-around if I find it. Any pointers are appreciated.
