I'll add that I have looked through PayPal help documentation. For example, I found the "Download Fields" page under "Reports" under PayPal Developer. That only lists the fields one can download. There is a link in the description of the Type field to Transaction Detail Report Specification which is giving me a 404 right now, but I think I have seen it and that describes T-codes which are not linked to the phrases that appear in the Type field of a download. I also think there was an instruction (vague for me) to "refer to the documentation." I am trying to look at the documenation. 😀
