QPR MEA Integration

QPR ProcessAnalyzer is able to connect to a QPR MEA (QPR Suite) instance and call its Web Service operations. To use the MEA connection, the following steps are required:

1. Create a connection string and store it as a secret.
2. Create a connection object.
3. Call web service operations using the connection object.

QPR MEA Web Service documentation: https://kb.qpr.com/qpr2025-1/qpr_web_service.html.

MEA Connection String

To connect to QPR MEA, the MEA connection string needs to be created and stored as a secret.

The MEA connection string is a json object with following properties:

• url: URL of the QPR MEA Web Service endpoint.
• logOnName: Log on name of the user who will access the QPR MEA Web Service.
• password: User's password in QPR MEA.

All QPR ProcessAnalyzer users who have access to the project where the connection string is stored, can use the MEA connection. The MEA user permissions in the connection string determine what operations can be done in the MEA side. For security reasons, if the intention is only to fetch data, the read-only permissions are sufficient for the MEA user.

Example connection string:

{ "url": "https://<hostname>/QPR/Portal/QPR.Isapi.dll/wsforward/MainService.svc/webHttp", "logOnName": "MyUser", "password": "MyPassword" }

MEA connection strings can be stored using the Project Properties dialog. Alternatively the expression language SetSecret function can be used as follows:

ProjectById(1).SetSecret("QprMea", "MeaConnection", `{ "url": "https://<hostname>/QPR/Portal/QPR.Isapi.dll/wsforward/MainService.svc/webHttp", "logOnName": "MyUser", "password": "MyPassword" }`);

MEA Web Service Operations

QueryObjects

Calls QueryObjects and returns query results as a hierarchical dictionary. More information: https://kb.qpr.com/qpr2025-1/queryobjects.html.

Parameters:

• Query (String): Actual query. See https://kb.qpr.com/qpr2025-1/query_syntax.html.
• Attributes (String): Comma-separated list of attributes that are included in the results. See https://kb.qpr.com/qpr2025-1/supported_parameters.html.
• Criteria (String): Results filtering criteria. See https://kb.qpr.com/qpr2025-1/parameters_and_options.html?anchor=globalparameters.
• Sort By (String): Comma-separated list of attributes for sorting results.
• Options (String): Optional options for the query. See https://kb.qpr.com/qpr2025-1/parameters_and_options.html?anchor=options.

Example: Return name and typename of all the subprocesses in a model whose name contains text "Account". Results are ordered by name and only at most three results are returned.

ProjectByName("TestProject")
  .CreateMeaConnection(#{"ConnectionStringKey": "MeaConnection"})
  .QueryObjects(
    "[PG.1374444994].Subprocess",
    "name, typename, isBpmnDiagram",
    `Find("Account", Name)`,
    "name",
    "MaxCount=3"
  );

CreateObject

Calls CreateObject and returns the MEA ID of the created object. More information: https://kb.qpr.com/qpr2025-1/createobject2.html.

Parameters:

• Namespace ID (String): MEA ID of the namespace into which the object is to be created.
• Object type name (String): Defines type of the new object.
• Name (String): Defines name for the new object.
• Parent IDs (String or String array): MEA ID of parent object. If array is given, every array element specifies one ID.
• Attributes (Dictionary): Key/value pairs of <attribute>/<attribute value> to be set for the created object.
• Options (String): Optional options for the operation. See https://kb.qpr.com/qpr2025-1/parameters_and_options.html?anchor=options.

Example: Connect to the configured QPR MEA and create a new top-level comment action.

ProjectByName("TestProject")
  .CreateMeaConnection(#{"ConnectionStringKey": "MeaConnection"})
  .CreateObject("PO", "Comment", "Test comment", "", #{"description": "Test comment description"});

DeleteObject

Calls DeleteObject. More information: https://kb.qpr.com/qpr2025-1/deleteobject2.html.

Parameters:

• Object IDs (String or String array): One or more MEA IDs of objects to be deleted. If array is given, every array element specifies one ID of object to be deleted.
• Options (String): Optional options for the query. See https://kb.qpr.com/qpr2025-1/parameters_and_options.html?anchor=options.

Example: Connect to the configured QPR MEA and delete an object.

ProjectByName("TestProject")
  .CreateMeaConnection(#{"ConnectionStringKey": "MeaConnection"})
  .DeleteObject("PO.0.985518423");

GetAttribute

Calls GetAttribute and returns the value of given object attribute as a string. More information: https://kb.qpr.com/qpr2025-1/getattributeasstring.html.

Parameters:

• Object ID (String): MEA ID of an object from which the attribute is fetched.
• Attribute (String): Name of the attribute that is queried. See https://kb.qpr.com/qpr2025-1/supported_parameters.html.
• Options (String): Optional options for the query. See https://kb.qpr.com/qpr2025-1/parameters_and_options.html?anchor=options.

Example: Returns the name of an object.

  .CreateMeaConnection(#{"ConnectionStringKey": "MeaConnection"})
  .GetAttribute(
    "[PG.785401983.683494101]",
    "name"
  );

Example: Read BPMN XML 2.0 diagram from QPR ProcessDesigner.

ProjectByName("TestProject")
  .CreateMeaConnection(#{"ConnectionStringKey": "MeaConnection"})
  .GetAttribute(
    "[PG.123.456]",
    "bpmnxml"
  );

SetAttribute

Calls SetAttribute to set an attribute value. More information: https://kb.qpr.com/qpr2025-1/setattribute.html.

Parameters:

• Object IDs (String or String array): MEA ID of an object from which the attribute is fetched. If array is given, every array element specifies one ID.
• Attribute (String): Name of the attribute that is queried. See https://kb.qpr.com/qpr2025-1/supported_parameters.html.
• Value (String): Value to be set for given attribute.
