# setRequestRemoteReferenceStatus

## Purpose

This operation updates the status of a remote reference in a request in PPM Center, as illustrated in the following example:

## Function

This operation provides the following functions.

- Update the status of the specified remote reference (the Source), in a PPM request (the Receiver). Remote reference is identified by the reference ID and server URL.

- Execute the workflow transition, if the given value of 'Status' exactly matches the transition name as appeared on the action buttons (case sensitive). This function is supported for backward compatibility. If the status does not match any of the transition names, no workflow transition will be performed. If you only want to perform workflow transition, use the executeWFTransitions operation.

- Update the simple fields of the request. This function is provided for backward compatibility. It is recommended to use the setRequestFields operation to update simple fields.

## Limitations

This operation has the following limitations:

- Only updates the status field of the remote reference. There is no operation to update the other remote reference fields.

- No security check on workflow transition. Even though the user cannot perform the transition from PPM Center standard interfaces, the transition will be performed with this Web service call, as long as the status value matches the transition name.

- Even when there is no simple field change, a simple field collection is still required when you call this operation.

Note: For more information, see:

- setRequestFields - set the value for simple fields in the request.

- executeWFTransitions - execute work flow transition for the request.

## Related Information

The following data types:

- Request

- simpleFields (type SimpleField)

- remoteReference

## Input

The following inputs are required for this operation:

- Receiver ID, which is the Identifier for the request in PPM Center.

- Source ID, which is to identify the remote reference. ServerURL is required.

- Status

- Simple field array. Even if there is no update on simple fields, it is still required.

## Return

Upon success, the operation returns the ID of the request.

## Java Interface

`SetRequestRemoteReferenceStatusResponseDocument
setRequestRemoteReferenceStatu(SetRequestRemoteReferenceStatusDocument in)`

Parameters | Description
--- | ---
SetRequestRemoteReferenceStatusDocument | Wrapper of the request ID, source ID, status, and the SimpleField[].
SetRequestRemoteReferenceStatusResponseDocument | Wrapper of the return code of this operation.

## Java Examples

Example: update a remote reference of an existing request.

    public class ExampleSetRequestFields {
    . . .
        private void setRequestFields(String serviceURL, String
    requestId) throws Exception {
    . . .
            // create the array of changed fields
            SimpleField[] fields = new SimpleField[2];

            // Set field 'Description'
            SimpleField field_A = SimpleField.Factory.newInstance();
            field_A.setToken("REQ.DESCRIPTION");
            field_A.setStringValue1Array(new String[] { "WebService
    Test (Update)" });
            fields[0] = field_A;

            // Set field 'Department'
            SimpleField field_B = SimpleField.Factory.newInstance();
            field_B.setToken("REQ.DEPARTMENT_NAME");
            field_B.setStringValue1Array(new String[] { "IS" });
            fields[1] = field_B;

            // Get web service
            DemandServiceStub stub = new DemandServiceStub(ctx,
    serviceURL);
            // Construct message to send
            SetRequestFieldsDocument inDoc =
    SetRequestFieldsDocument.Factory.newInstance();
            SetRequestFieldsDocument.SetRequestFields
    setRequestFields = inDoc
                    .addNewSetRequestFields();
            setRequestFields.setRequestId(reqId);
            setRequestFields.setFieldsArray(fields);
    . . .
    }
    }
