When you enter information in the Station Operations Dialog the data will go direct into N-OC, but it will not trigger an event. If you need to feed other systems, you have to create a Business Job.
Build the message you want to send
Create a Message Body of Data type "Company Activity"
Build the message. In this example it is a TypeB LDM
If you want to send by email it is a good practice to have a "subject" template.
We will create a Legfilter that will check if the "TotalActulCompartmentLoad" is greater than one.
Create a business job where you have attached the Filter and message templates.
The business job will check every 60 seconds if there is a change to the Load on the flights, if it find a change it will create a message.
