Determining Report Parameter inheritence ie Effective Report Parameters

Can you please describe your use-case why you are needing this? The functions to determine the effective report parameters are part of the object layer business logic and are not using a single ootb SQL function.

Use case is as follows 

Customer would like to have Reports exported to share on MS Server.

Per Report definition - they would like to define : 

1 : Name of output file - that is not overwritten by Subscription name as in OOTB

2 : Ability to specify file output type eg pdf vs XSLX - per Report Defintion.

3 : Ability to have varying "Lifetime" / Aging that deletes old versions of reports.

Custom Process on RPSSubscription created to export file using these Report Parameters. - using RPSSubscription model to provide context for user directory / permissions to be assigned. (Central Account added to Report storage path - similar to OOTB)

Custom process developed to clean up reports on schedule - based on lifetime provided by paramter.

Problem is - in order to have the parameters linked to the RPSSubscription paramterset - cannot make them fixed on the report definition (DialogReport) - they are only then shown against the DialogReport Parameter set - not the RPSReport or RPSSubscription version / parameter set . . .  Ideally - these Fixed paramters would be set once on the DialogReport parameterset - and inherited - preventing overwrite by Subscriber.

Is see in the Object Layer documentation there is reference to : Parameter.GetData(Of TParam, TVal) Method (Func(Of TParam, TVal)) 

Do you happen to have an illustration / example of this in use - returning inherited values or defaults ? 

Thanks

What version are you using?

v 7.1.4

Assuming that your process is running at the table RPSSubscription (hence Entity is an RPSSubcription) and assuming that your RPSSubscription entity has an assigned DialogParameterSet via DialogParameterSet.ObjectKeyUsedBy then you can access the value of a parameter with the following code. The code will fetch the value according to the parameter hierarchy as documented in the manuals.

Dim pSet as IDialogParameterSet = VI.DB.DialogParameterSet.LoadFor(Session, Entity)
Value = pset.Item("ParameterName").Value

If you have more than one parameter you need to access in your code, you might want to create the DialogParameterSet in the pre-script to minimize round-trips..

Thank you - that worked perfectly . ..
