+APPC Legacy Actor
+#################
+
+.. contents::
+ :depth: 3
+
+Overview of APPC Legacy Actor
+#############################
+ONAP Policy Framework enables APPC Legacy as one of the supported actors.
+APPC Legacy uses a single DMaaP topic for both requests and responses. As a result, the
+actor implementation must cope with the fact that requests may appear on the same
+stream from which it is reading responses, thus it must use the message content to
+distinguish responses from requests. This particular implementation uses the *Status*
+field to identify responses.
+
+In addition, APPC may generate more than one response for a particular request, the
+first response simply indicating that the request was accepted, while the second
+response indicates completion of the request. For each request, a unique sub-request
+ID is generated. This is used to match the received responses with the published
+requests.
+
+Each operation supported by the actor is associated with its own java class, which is
+responsible for populating the request structure appropriately. The operation-specific
+classes are all derived from the *AppcOperation* class, which is, itself, derived from
+*BidirectionalTopicOperation*.
+
+
+Request
+#######
+
+CommonHeader
+************
+
+The "CommonHeader" field in the request is built by policy.
+
+=============================== =========== ==================================================================
+ "CommonHeader" field name type Description
+=============================== =========== ==================================================================
+SubRequestID string Generated by Policy. Is a UUID and used internally by policy
+ to match the response with the request.
+RequestID string Inserted by Policy. Maps to the UUID sent by DCAE i.e. the ID
+ used throughout the closed loop lifecycle to identify a request.
+=============================== =========== ==================================================================
+
+Action
+******
+
+The "Action" field uniquely identifies the operation to perform. Currently, only
+"ModifyConfig" is supported.
+
+Payload
+*******
+
+=============================== =========== ==================================================================
+ "Payload" field name type Description
+=============================== =========== ==================================================================
+generic-vnf.vnf-id string The ID of the VNF selected from the A&AI Custom Query response
+ using the Target resource ID specified in the
+ *ControlLoopOperationParams*.
+=============================== =========== ==================================================================
+
+Additional fields are populated based on the *payload* specified within the
+*ControlLoopOperationParams*. Each value found within the *payload* is treated as a
+JSON string and is decoded into a POJO, which is then inserted into the request payload
+using the same key.
+
+
+Examples
+########
+
+Suppose the *ControlLoopOperationParams* were populated as follows:
+
+.. code-block:: bash
+
+ {
+ "actor": "APPC",
+ "operation": "ModifyConfig",
+ "target": {
+ "resourceID": "2246ebc9-9b9f-42d0-a5e4-0248324fb884"
+ },
+ "payload": {
+ "my-key-A": "{\"input\":\"hello\"}",
+ "my-key-B": "{\"output\":\"world\"}"
+ },
+ "context": {
+ "cqdata": {
+ "generic-vnf": [
+ {
+ "vnfId": "my-vnf",
+ "vf-modules": [
+ {
+ "model-invariant-id": "2246ebc9-9b9f-42d0-a5e4-0248324fb884"
+ }
+ ]
+ }
+ ]
+ }
+ }
+ }
+
+An example of a request constructed by the actor using the above parameters, published
+to the APPC topic:
+
+.. code-block:: bash
+
+ {
+ "CommonHeader": {
+ "TimeStamp": 1589400050910,
+ "APIver": "1.01",
+ "RequestID": "79e1d7d4-bac1-4399-8ee5-f84419c5723d",
+ "SubRequestID": "ee3f2dc0-a2e0-4ae8-98c3-478c784b8eb5",
+ "RequestTrack": [],
+ "Flags": []
+ },
+ "Action": "ModifyConfig",
+ "Payload": {
+ "my-key-B": {
+ "output": "world"
+ },
+ "my-key-A": {
+ "input": "hello"
+ },
+ "generic-vnf.vnf-id": "my-vnf"
+ }
+ }
+
+
+An example initial response received from APPC on the same topic:
+
+.. code-block:: bash
+
+ {
+ "CommonHeader": {
+ "TimeStamp": 1589400050923,
+ "APIver": "1.01",
+ "RequestID": "c7c6a4aa-bb61-4a15-b831-ba1472dd4a65",
+ "SubRequestID": "ee3f2dc0-a2e0-4ae8-98c3-478c784b8eb5",
+ "RequestTrack": [],
+ "Flags": []
+ },
+ "Status": {
+ "Code": 100,
+ "Value": "ACCEPTED"
+ }
+ }
+
+
+An example final response received from APPC on the same topic:
+
+.. code-block:: bash
+
+ {
+ "CommonHeader": {
+ "TimeStamp": 1589400050934,
+ "APIver": "1.01",
+ "RequestID": "c7c6a4aa-bb61-4a15-b831-ba1472dd4a65",
+ "SubRequestID": "ee3f2dc0-a2e0-4ae8-98c3-478c784b8eb5",
+ "RequestTrack": [],
+ "Flags": []
+ },
+ "Status": {
+ "Code": 400,
+ "Value": "SUCCESS"
+ }
+ }
+
+
+Configuration of the APPC Legacy Actor
+######################################
+
+The following table specifies the fields that should be provided to configure the APPC
+Legacy actor.
+
+=============================== ==================== ==================================================================
+Field name type Description
+=============================== ==================== ==================================================================
+sinkTopic string Name of the topic to which the request should be published.
+sourceTopic string Name of the topic from which the response should be read.
+timeoutSec integer (optional) Maximum time, in seconds, to wait for a response to be received
+ on the topic.
+=============================== ==================== ==================================================================
+
+The individual operations are configured using these same field names. However, all
+of them are optional, as they inherit their values from the corresponding actor-level
+fields.
