I am currently working on The essentials of Model Building for customers
I have not started my Lessons training. However, I am nearing completion of the essentials of model building in the customer module. I am in course 7.6 Drill to Transaction functionality. I have tried to drill down on Pet and Food supplies expenses but get an error message. I have posted a screen shot. I am not quite sure whether I am doing something wrong or there is a problem with the model.
