I had gone to Central Administration, to the Secure Store Services and created the "Target Application ID" and have already set permissions and credentials. Also, I have set the permissions in the "Business Data Connectivity Application". This removed the - BDC and NT\Authority errors that I had, now I have the error noted above and don't remember how to remove it. Thank you for your help.

I Fixed it! What I learned is that parameters were not set. This has happened to me twice. When parameters/filters are not set, the return of data is too large to be passed and an error as the one noted is given. I tried going back to add filters/parameters, but instead recreated the ECT, the only difference was this time filters were added. :)
