As I build custom entry screens for our business requirements, an objective is to utilize generic inquiries as the entry point for a consistent user experience with the rest of the system. I have 3 user entry screens, each of which is on the Site Map in the same place. Two of the GI's allow me to select the Site Map node for these user screens and assign the Entry Point to display the GI instead of the user entry screen. One does not. All of them appear to have very similar DAC structure as well as Graph structure including naming the primary graph in the DAC.
What causes the site map node to be available (or not) for assignment of the GI as an entry point. (For instance, is there an orphaned record I might seek out in SQL from deleting a previous attempt?)
I am on Acumatica ERP 2018R1 (Build 18.113.0018).
There were a couple of issues that prevented the Generic Inquiry from allowing it to be set as an Entry Point. If you have this same issue, review the related DAC's carefully for errors that may not be compile time issues. Also, double check all of the definition tabs in the generic inquiry for fields that you renamed or dropped but failed to adjust in the GI. In my case, the last issue resolved that allowed the GI to be turned into an entry screen was a poorly defined parameter.
To troubleshoot, try making the GI very simple. If you cannot reach the screen to select as the entry point and the GI is very basic, odds are that you have a problem somewhere in the DAC. In some of the DAC's for screens that I could not setup as an entry point, I had reference to a setup DAC that was not using Currrent when it should. This small error in the DAC was the problem on 2 of my 3 screens.
