QPR ProcessAnalyzer Objects in Expression Language

Filter

Filters contain a set of filter rules used to filter cases and events in models. Filters are objects located in the models. Filters are owned by the creator user, and when a filter publish mode is private, only the creator can use it.

Filter properties	Description
CreatedBy (User)	Returns the user who created the filter.
CreatedDate (DateTime)	Returns date when the filter created date.
Description (String)	Returns description of the filter.
Id (Integer)	Returns id of the filter.
LastModifiedBy (User)	Returns user who modified the filter.
LastModifiedDate (DateTime)	Returns date when the filter last modified.
Model	Returns model where the filter belongs to.
ModelId (Integer)	Returns model where the filter belongs to.
Name (String)	Returns the name of the filter.
Project	Returns project where the filter belongs to.
ProjectId (Integer)	Returns project id where the filter belongs to.
PublishMode (String)	Returns publish mode of the filter, one of the following: Private, Public, or Default.
Rules (Dictionary)	Returns a dictionary containing the filter rules in this filter.

Model

Notes:

• For models that are offline, the object counts represent the situation when the model was last time online (loaded into the memory). null is returned if the model has never been loaded into the memory.
• If Case permissions are used for the model, and user doesn't have GenericWrite permission for the model, null is returned for data security reasons. Users that have the GenericWrite permission, see null when the model is offline, and when online, they see counts where the case level permissions settings are applied.
• Using CaseAttributes, EventAttributes and Eventlog properties requires the model to be loaded into the memory. If the model is not in the memory, it is loaded when these properties is used. Other Model object properties down require the model to be in the memory.

Model properties	Description
Calendars (BusinessCalendar*)	Returns all business calendars stored to the Model as an array. Returns an empty array, if there are no business calendars stored to the model. Note: UI allows to set only one business calendar for a Model.
CaseAttributes (AttributeType*)	CaseAttributes in the model returned in the alphabetical order. Using this property requires that the model is loaded in the memory. If the model is not in the memory, it's loaded when this property is used.
CasesDatatable (Datatable)	Returns the Datatable the model uses as a datasource for cases. Returns null if the cases Datatable is not defined or if model uses other than the Datatable datasource.
Configuration (Dictionary)	Returns the Model configuration as dictionary. Example: ModelById(123).Configuration.DataSource.Events.DataTableName
ConfigurationJson (String)	Returns the Model configuration as JSON string.
CreatedBy (User)	User who created the model.
CreatedDate (DateTime)	Timestamp when the model was created.
DefaultCalendar (BusinessCalendar)	Returns the default business calendar of the Model. Returns null, if there are no calendars in the Model or no calendar has been set as a default calendar. Note: UI allows to set only one business calendar for a Model, which is also the default calendar.
DefaultFilterId (Integer)	Default filter id of the model. Returns null if the model does not have a default filter.
Description (String)	Model description. The model description may contain line breaks.
DeletedDate (DateTime)	Timestamp when Model was deleted (moved to the recycle bin).
DeletedBy (User)	User how deleted the Model.
EstimatedMemory (Integer)	Returns an estimation of how much memory in bytes the model requires.
EventsDatatable (Datatable)	Returns the Datatable the model uses as a datasource for events. Returns null if the events Datatable is not defined or if model uses other than the Datatable datasource.
EventAttributes (AttributeType*)	EventAttributes in the model returned in the alphabetical order. Using this property requires that the model is loaded in the memory. If the model is not in the memory, it's loaded when this property is used.
EventLog (EventLog)	EventLog containing the entire model (i.e. event log where no filters have been applied). Using this property requires that the model is loaded in the memory. If the model is not in the memory, it's loaded when this property is used.
Filters (Filter*)	Returns an array of all filters in the model.
Id (Integer)	Model Id. Model Id is generated by QPR ProcessAnalyzer when the model is created.
LastModifiedBy (User)	User who last time modified the model properties. Note that datatables containing the eventlog data are separate objects having similar fields to track the last modification and last data import.
LastModifiedDate (DateTime)	Timestamp when the model was modified the last time.
Name (String)	Model name.
NBookmarks (Integer)	Number of bookmarks in the model.
NCache (Integer)	Number of objects related to the model when the model is loaded into the memory.

NFilters (Integer)	Number of filters in the model.
NOpens (Integer)	Number of times analysis has been requested from the model.
Project (Project)	Project where the model belongs to.
ProjectId (Integer)	Project id where the model belongs to.
Status (String)	Memory availability status of the model. There are the following statuses: Loading: The model is currently loading into the memory. When the loading is ready, the status changes to online. If the loading fails, the status changes to offline. Offline: The model is currently not loaded into the memory. The model needs to be loaded into the memory, so that analyses can be calculated from the model (occurs automatically when an analysis is requested). Online: The model is in the memory and ready for analysis calculation. If the model is dropped from the memory, its status changes to offline.

Model Function	Parameters	Description
CalendarByName (BusinessCalendar)	name (String)	Returns a business calendar stored to the Model by the name of the calendar. Business calendars can be stored to models in the model properties. Returns null, if a calendar with the provided name is not stored to the model. Examples: ModelById(123).CalendarByName("MyCalendar")
CreateFilter (Filter)	Parameters dictionary	Creates a filter to the model. If a filter with that name does not exist in the model previously, a new filter is created. If a filter with that name already exists in the model, an exception is thrown. The parameters dictionary may have the following properties: Name: Name of the filter. Description: Description of the filter Rules: Rules defined for the filter PublishMode: publish mode (private, public or default) of the filter Requires GenericWrite permission for the Project and global CreateModel permission. Example: create a new filter to a model: let newFilter = modelById(1).CreateFilter(#{ "Name": "My Filter", "Rules": #{ "Items": [ #{ "Type": "IncludeCases", "Items": [ #{ "Type": "CaseAttributeValue", "Attribute": "Account Manager", "StringifiedValues": [ "0Robert Miller" ] } ] } ] }, "PublishMode": "Public" }); }

Restore	(none)	Restores the Model from the recycle bin back to the original location.
TriggerNotifications (Boolean)	Notification names (String*)	Triggers the given notifications for the Model. Notifications are given by their names. Triggering means that the configured rules are run and notification emails are sent as defined by the rules. If the notification names parameter is not provided, all notifications in the Model are triggered. The function return true if any notification were triggered, otherwise false. ModelById(123).TriggerNotifications(["Notification 1", "Notification 2"]); Triggers notifications Notification 1 and Notification 2 in model id 123. ModelById(123).TriggerNotifications(); Triggers all notifications in model id 123.

Script

Scripts are entities that contain executable code, that can be run. Usually scripts contains ETL routines but also other kind of tasks are possible.

Script properties	Description
Code (String)	Script code.
CreatedBy (User)	User who created the Script.
CreatedDate (DateTime)	Timestamp when the Script was created.
CurrentRunStart (DateTime)	Timestamp of the current run start. Null if the script is currently not running.
Description (String)	Description of the Script.
Id (Integer)	Id of the Script.
Language (String)	Either of the following scripting language: Expression or SQL. When language is Expression, the script is run as an expression script, and when language is SQL, the script is run as an SQL script (using the sandbox database).
LastModifiedBy (User)	User who last modified the Script.
LastModifiedDate (DateTime)	Timestamp when the Script was last modified.
LastRunEnd (DateTime)	Timestamp of the last completed script run end (either successful completion or failure). Null if the Script hasn't been run yet.
LastRunResult (String)	Result of the last run. Options are: Completed: The last run was completed successfully. Failed: An error occurred during the last run, so likely the script did not complete as intended. Aborted: Script run was manually stopped prematurely by a user, so the script did not proceeded in the end. Null if the Script hasn't been run yet.
LastRunStart (DateTime)	Timestamp of the last completed script run start time. Null if the Script hasn't been run yet.
Name (String)	Name of the Script.
OperationId (Integer)	Id of the operation which runs the Script. Null if the script is currently not running.
Project (Project)	Project where the Script is located. Null if the script is in the global context.
ProjectId (Integer)	Id of the project where the Script is located. Null if the script is in the global context.
Status (String)	Current status of the script. Options are: Ready: Script is not running. In this status, the script can be started (changing the status to Running). Running: Script is running. In this status, the script can be stopped (changing the status to Stopping). Calling stop just requests a script to stop, and the actual stopping occurs some time later. Stopping: Script has been requested to be stopped, but it's still running. In this status, neither start nor stop can be called for the script. When the script eventually stops, its status changes to Ready.

Script functions	Parameters	Description
Run (Object)	Dictionary of parameters	Runs the script using the provided parameters. The parameters are available in the script as variables (see the example). Any type of variables can be passed to the script. Note that if the script assumes certain variables, but that they are not passed to the script, the script run will throw an error. For SQL scripts, the passed parameters are available in the script as variables in format @_parameter_<ParameterName> where <ParameterName> is the name of the parameter, e.g. parameter_myParameter1. Only string type of parameters can be used, so any other type of data in parameter values is converted into strings. The return value of the script is returned by the Run function. Expression scripts return a value with the return statement or alternatively the result of the last line of the script is the return value. If the script does not return any value, the Run function returns _empty. For SQL scripts, the return value is the last dataset produced by the script (returned as a DataFrame) (SQL scripts might create several datasets using the --#ShowReport command or the Show parameter). When a script is called using the Run function, the called script status does not change, because the it's the parent script that is Running. Also the called script log is not filled, but instead the logging goes to the calling script. It's possible to call a script using the Run function several times simultaneously. If there is an error when running the called script, the Run function throws the error to the calling script. Scripts are run in the script entity context, so for example the following properties are available: Id: Script id Name: Script name Project.Id: Project id where the script is located Project.Name: Name of the project where the script is located Example: Following script (id 123) raises a specified number to a specified power: return Pow(numberToRaise, exponent); The script can be called as follows: let runResult = ScriptById(123).Run(#{ "numberToRaise": 4, "exponent": 2 }) Returns: 16

Function to get a script by the script id:

Function	Parameters	Description
ScriptById	Script id (Integer)	Returns Script object corresponding to the given script id. If script with the given id doesn't exist or user doesn't have permissions to it, an error is given.

User/Group

User objects represents users and user groups. Note that some properties can only be used for users and some for groups.

User/group properties	Description
Description (String)	Description of the user.
Email (String)	Email address of the user.
FullName (String)	Full name of the user or group name.
GlobalPermissions (String*)	Array of global permissions of the user. Global permissions come from the global roles assigned to the user and groups that the user belongs to. Note that to get the effective permissions for certain objects, also project specific permissions need to be taken into account.
GroupMemberNames (String*)	Array of names of members of a user group. This property is available for groups.
GroupMembers (User*)	Array of members of a user group. This property is available for groups.
GroupNames (String*)	Array of names of user groups the user belongs to. This property is available for users.
Groups (User*)	Array of user groups the user belongs to. This property is available for users.
Id (Integer)	Id of the user, which is unique for every user.
IsActive (Boolean)	Returns true only if the user is active (not disabled).
IsGroup (Boolean)	Returns true if the user is a user group.
Name (String)	Login name of the user or group.
Roles (Object**)	Returns all roles of the user (both global and project roles) as a nested array structure. Example: ToJson(Users.Where(name == "qpr").Roles) Returns (for example): [ [{"calcId": "Project:1"}, "Administrator"], [{"calcId": "Project:2"}, "Analyzer"], [{"calcId": "Project:3"}, "Viewer"], [null, "RunScripts"], [null, "Administrator"] ]

User/group functions	Parameters	Description
EffectivePermissionsFor (String Array)	Project to get permissions	Returns effective (actual) permission of the user to the given project. Project is given as a project object (not as a project id). Effective permissions determine the actual permissions that the user has, i.e. a combination of all permissions assigned to the user and groups the user belong to, including both project specific and global roles. Permissions for the EffectivePermissionsFor function are as follows: All users can query their own permissions To get permissions for any user, the user needs to have ManageUsers permission. Note that inactive users don't have any effective permissions, so the EffectivePermissionsFor function does not return any permissions for those users. Examples: EffectivePermissionsFor(ModelById(1234).Project) Returns (for example): ["EditDashboards", "Filtering", "GenericRead"]
