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.

Example connection string:

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

Example to store secret:

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

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",
    `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*): MEA ID of parent object. If array is given, every array element specifies one ID.

• 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:

  .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.

    "[PG.785401983.683494101]",
    "name"
  );

SetAttribute

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