I have recently started using Power BI and till now have basically created 4 reports. My data source is a custom connecter with .mez extension provided by the warehouse management system. I directly use this connector using Get Data option and it gives me below view-I use the tables that i need and apply transformation steps in Power query and click apply.What I find is that it takes about an hour to upload data when I click Close and apply. Also, after creating 3 reports, when I clicked Close and apply for this 4th one, it showed me this below error after refresh for about 1 and half hour. I do not know what is consuming space and how can I free up the space or why is this happeneing only after crating 3 basic reports. My Data load looks like below-My Laptop's specification are-

learner03 Measures will not affect data load, only calculated columns. The code looks relatively innocent enough. You can use performance analyzer in Power Query Editor to perhaps see what row is taking the most time. Alternatively, duplicate your query and disable load on the duplicate. Then on the original, remove half the steps from the bottom and see if the issue persists. If so, remove another half of the steps. Otherwise, if the issue is gone, then add half of the steps you removed. In this manner, zero in on what is causing the problem.
