Just a quick post to highlight an issue I came across that I thought might be worth posting about in case anyone else runs into the same issue. In Project Online, in PWA you can export most of the grids to Excel. I was testing something in PWA and came across an issue exporting the Capacity Planning grid to Excel, I clicked the button but nothing happened, the details grid would flicker when the button was clicked but nothing after that. Opened the browser debugger and tried again, no console errors but looking at the Network log an error 500 was thrown for the ProjectServer.svc:
Looking at the response I could see a general unhandled exception was thrown caused by a key not being present in the dictionary:
Looking at the request payload I could see two resource GUIDs were included:
Looking at the grid data there was only one resource present:
Looking back in the Resource Center, I did have two resources selected:
One being a Cost resource, I deselected the Capex resource and tried the Export to Excel from the Capacity Planning page and all worked as expected.
If you do run into the issue with exporting the Capacity Planning grid to Excel, check the resource types you have selected, deselect Cost and Material resources then try again and hopefully that will resolve the issue for you. I will mention this to the Project team at Microsoft to see if this is something they are already aware of.
