I noticed that after selecting in the Template Columns for Essential Meds "Enable Stock on Hand to populate from stock cards" and initiating a requisition there is a gateway time-out.
Log in as an administrator and go to Administration > Requisition Templates.
Click the "Configure" button next to Essential Meds, select "Enable Stock on Hand to populate from stock cards" and click "Save".
Go to Requisitions > Create/Authorize and try to initiate requisition for Comfort Health Clinic and program Essential Meds.
Gateway Time-out error appears.
Requisition should be initiated.
NOTE: I also noticed that when I want to re-initiate the requisition, I get the information that it is already initiated.
After refreshing the page, initialized requisition appears.
