Hi,
I have created a custom screen replicating the Sales Order Screen and upon loading of the OWL screen, "500 SAP Internal Server Error" Pops. I have attached a screenshot for reference. Also, I have followed these steps for the creation/replication of the Sales Order Screen https://blogs.sap.com/2015/04/23/how-custom-queries-work-on-owl/. Appreciate all the help.

Thanks and Regards,
JM Angeles
