I created 3 services that us AddOrUpdateAlerts() : below _ above _in range. i think I should put all those services on a subscription if i want to use the button to trigger those services ?
also i have a problem with thresholds precisely at the point of calling service for in range :
for example : alert1 : measure <10 ===> call service for below alert
alert2: 10<=measure <20 ===> call service for in range alert
alert3: 80<=measure <100 ===> call service for in range alert
alert4: measure >100 ===> call service for above alert
Subscriptions are used to be executed when a specific event is happening (Alert, DataChange), so if this is corresponding to what you want to accomplish then it is ok to use it.
Otherwise, think what you want to trigger the service: a click on a button, selected rows changed, all data changed etc.
To execute a service more than once in mashup, you need to change the bindings, so one idea is to get once again the service in the Data panel and create once again the bindings.
I would work with one service for every alert, but I don't know exactly what you need to do or if this fits to your case.
If one of the previous responses allowed you to find a solution, please mark the appropriate one as the Accepted Solution for the benefit of others with the same issue.
