Hello,
I am trying to run a pretty simple GP Excel to Table. The document in question has a large number of maps (50+, I think), and the tool with start fine but never finish. Other Pro projects I've tested in don't run into this issue, so I made a new dummy project and steadily added maps from the original until the tool hit the same issue. I was able to successfully run table to excel with 15 maps, but the 16th wound up resulting in a hanging process. I've reproduced this with different combinations of maps in the document. Is this expected behavior? Is there an upper limit for the amount of in-project content that can exist without disrupting GP tools?
