You can open a report in the Report Processing dialog by calling the action:

reports.run with the parameter id={Portal-Report-Item-ID

If you want the report to run in the background, add the parameter entry runInBackground=true.

Like in the entry point specification, you can specify report parameter values by adding the parameter name and the desired value in the parameter.

To also specify the objects to run, add a FeatureIDs entry with the comma-separated ObjectIDs.

If an ObjectID does not exist in the database, the report is generated without that object. No error is returned.

The following is an example of a parameter:

{
id: "d26540bb43724c6395df715591038298",
runInBackground: "true",
author: "John Smith"
featureIDS: "112,287,1854,4672"
}

This parameter starts the generation of the report with id d26540bb43724c6395df715591038298 in the background, defining the parameter author to be John Smith.

The generated report will contain four objects that are specified by their ObjectID in the featureIDs parameter (112,287,1854,4672).
